@Danmichaelo, is lossless mode still working. I used to get messages that the crop size had been adjusted because I wasn't starting on a multiple of 8 or 16, but this has gone away. Similarly, there's a bug report on github (#170) reporting that files that should be uncroppable in lossless mode are now working, but produce the same files as if they were in precise mode. Is the tool silently falling back to precise when lossless doesn't work (which would be undesirable), or is something else going on here? Perhaps a bug introduced in the September 2020 refactoring? Ahecht (TALK

Looking into the code more, it seems like the September 2020 refactor fundamentally broke things. The various types of crop were broken out into subclasses (for example, lossless Jpeg cropping was broken out into JpegFile and Gif cropping to GifFile), but as far as I can tell the only subclasses that are actually being called out by the program in FileRepository.php are TiffFile, DjvuFile, PdfFile, and SvgFile, all of which return errors instead of actually working. All other file types are being handled by the generic imagemagick call in File.php.

This is why lossless crops are no longer lossless, Gif files say they are being cropped with precise or lossless mode instead of "gif mode", and TIFFs, PDFs, and DJVUs no longer work.

If these issues aren't easy to resolve, perhaps to the tool should be rolled back to 1.4 (before the refactoring). Ahecht (TALK

Since about 9-2021 Danmichaelo's only contributions have been edits to wikidata and some edits in norwegian and finnish wikipedia about some meta-topics (bot problems, ...). I seem to remember that them was unhappy with a decission at english wikipedia. That leaves two ways of action: Appease them to return to wikipedia, or find a new maintainer for croptool.

Is there any Similar to Croptool tool to change exposition? Alex Blokha (talk) 23:06, 18 February 2025 (UTC)Reply

@Alex Blokha: not sure what you mean by "exposition". Maybe lightness ("exposure", though technically "exposure" happens entirely at the time you snap the shutter, so exposure as such cannot be changed)? Or do you mean something else? - Jmabel ! talk 00:04, 19 February 2025 (UTC)Reply

Yes, I mean lightness. I need to make image more light or more dark. Alex Blokha (talk) 01:09, 19 February 2025 (UTC), and a good tool for that takes a good bit of work; it's tricky to do client-side in a browser window. (Theoretically you could do it with JavaScript and HTML Canvas.) I'd suggest that if you need to do that, download a full-res copy to your own PC and do it there. The Colors > Curves tool in GIMP does this well and flexibly (e.g. lets you keep highlight as they are while lightening other ranges). - Jmabel ! talk 05:46, 19 February 2025 (UTC)Reply

User:Alex Blokha Yes we built this [1] Doc James (talk · contribs · email) 16:43, 27 March 2025 (UTC)Reply

@Doc James: I don't see anything there that looks like it has the requested capability. It looks to me like strictly a tool for adding text annotations to an image, not for making it brighter or darker. Am I missing something? - Jmabel ! talk 01:47, 29 March 2025 (UTC)Reply

Under "filters" bottom right and then you can move the brightness toggle. You have to select the square box to the left first. Doc James (talk · contribs · email) 19:35, 29 March 2025 (UTC)Reply

I see. That lets you change brightness over the whole image, and might deal well with straight-out overexposure or underexposure. However, in my experience, that's not terribly useful. You really want at least to be able to adjust shadows, midrange, and highlights independently, and probably the different color channels, and ideally have something like the GIMP "Curves" tool. So, yes, there are some cases that would cover, but I suspect it is a definite minority. If you want a good example of where it won't help, try looking at File:Pfeiffer Big Sur State Park - tree round 01.jpg. - Jmabel ! talk 22:29, 29 March 2025 (UTC)Reply

How can I put it to sidebar like Croptool? Alex Blokha (talk) 20:24, 26 May 2025 (UTC)Reply

Ок, I've written script for sidebar by myself, using LLM

// <nowiki>

mw.loader.using(['mediawiki.util'], function () {

/**

* Check if we are in the "File" namespace (Namespace ID 6).

* If not, the script skips execution.

if (mw.config.get('wgNamespaceNumber') === 6) {

// Get the full page name (e.g., File:Kkpk_truck_in_Dnipro.png)

var pageName = mw.config.get('wgPageName');

// Construct the URL for the ISA Tool

// encodeURIComponent ensures special characters are handled correctly

var targetUrl = 'https://image-annotation-tool.wmcloud.org/?file=' + encodeURIComponent(pageName);

// Add the link to the sidebar toolbox (Portlet Link)

mw.util.addPortletLink(

'p-tb', // ID of the "Tools" portlet (Toolbox)

targetUrl, // The target URL

'ISA Tool', // Link text to display

't-isa-tool', // Unique ID for the HTML element

'Open this file in the Image Annotation Tool', // Tooltip text (on hover)

null, // Access key (can be null)

null // Next node (null = append to the end of the list)

);

}

});

Have code here User:Doc James/common.js Doc James (talk · contribs · email)

If images have been annotated before cropping (like e.g. mountain peaks), my impression is that these annotations will be broken upon cropping, as the image width and / or height will not fit the parameters in the Template:ImageNote expressions any more (broken usually means: they will not be displayed at all). Recent example: File:Palù Unterkrumpwasser - m 2228 s.l.m. (BZ) - panoramio.jpg, cropped by User:Joalbertine vertically (the width remained the same, the height was reduced by 90px). As a "quick and dirty" workaround, it is possible to adjust the image height parameters in the file manually (that is what I just did in the file mentioned), which works fine if the (mountain) image is cropped only by height and the annotation boxes are close to the upper end of the image (where the zero coordinate is located). If also horizontal cropping only at the right hand side is done, everything is still fine. If a vertical strip was cropped at the left hand side, though, the position coordinates would have to be corrected manually somehow.

I see that such corrections of the latter case can probably hardly be done automatically. As a workaround, however, I'd suggest that 1) at least the image width / height parameters in the ImageNote expressions could be adjusted automatically (then the annotation boxes would at least be displayed, even though not precisely at the correct position. If appropriate, I would suggest to 2) add a warning like "Attention: this image was annotated and cropped later. The positions of the annotation boxes may not be accurate any more." And / or 3) during the process of using the Croptool, a warning could show up that says something like: "Attention: You are about to crop an annotated image. If you proceed cropping, the annotations may be broken or inaccurate afterwards. Please check the annotations manually afterwards or ask the original user who did the annotations for help." What do you think?

I'm doing annotations quite often (predominantly mountain photographs), and I would regret if they are broken after any cropping. --Kuhni74 (talk) 10:33, 14 July 2025 (UTC)Reply

Hi - nice tool! But definitely has the annotation problem described by Kuhni74!

As the crop tool does no or no complicate rotations (maybe only changing the exif orientation entity?), recalculation of the annotation coordinates should be a nice challenge for some kind of programming workshop, coding summer or something like that. Shouldn't really be that difficult.

Until that feature is added, for images with annotations there should definitely be:

a warning before saving
the original should not be overwritten
plus there should always be a note in the edit summary

Nice example for what the problem is [2] -- Schusch (talk) 13:42, 6 November 2025 (UTC)Reply

the original should not be overwritten: I occasionally use the CropTool to crop annotated images. I consistently clean up the ImageNotes afterward. I would not want to lose the ability to use the crop tool for this. A warning is fine, but it needs to be possible to override it. Probably it should add a maintenance category, which a user could remove after cleaning it all up. (Of course, having the CropTool actually fix the annotations would be better.) - Jmabel ! talk 18:46, 6 November 2025 (UTC)Reply

As the crop tool does no or no complicate[d] rotations: not true, you can rotate by any multiple of 0.01 degree. - Jmabel ! talk 18:46, 6 November 2025 (UTC)Reply

crop annotated images: cropping as i realize it is mostly without rotating - so recalculation of coordinates for annotations should be easy (algorithm should work something like this: recalculate box borders, check if box is completely in new frame, if yes, insert, if not, check if remaining rest of box is at least x pixel (with x = 20? or at least 2 % of height or width?) high or wide - if big enough, add remaining rest of box to image, otherwise dismiss the box completely); so if the annotation are lost at least there would be the note in the edit summary ... (and we have a version history :-)
rotating by any multiple of 0.01 degree: didn't realize the rotating possibility in my very short check (never used the tool up to now), sorry for that ... but even then it should not be very difficult to integrate a calclulation for new coordinates

as I said: for me it sounds like a nice task for programming course or competition - if there are such events in the wiki[p|m]edia world ... -- Schusch (talk) 19:29, 6 November 2025 (UTC)Reply

Hi, is anyone working on this issue? This is a consistent problem in all cropped files (for example, File:Andrees Handatlas - Haiti und Puerto Rico.jpg) and I don't think it is my responsability as the one who does the cropping, to fix the template in the resulting image, especially since the github people purposefully programmed it that way to discourage usage of the {{book}}-template. --Enyavar (talk) 10:28, 24 July 2025 (UTC)Reply

@Doc James: can this issue also be looked into please? I work with PDF and DJVU files a lot of times and the resulting image post crop has broken templates. I've had to manually fix those.

I would suggest - Crops from files using the Book template should use the basic Information template and an optional field to enter the new description (especially when uploading a new image) would be great. PDF and DJVU templates on the result file should also be removed. Ciridae (talk) 13:13, 6 January 2026 (UTC)Reply

So basically if the starting image uses the book template than the final image should use the book template? User:Bawolff can we add this functionality per the bug report? Doc James (talk · contribs · email) 14:24, 6 January 2026 (UTC)Reply

@Doc James: No, even if the starting file, PDF or DJVU, uses the Book template, the final cropped image should use the Information template by default because the final image will never be a book but an image file. Also, a PDF or DJVU template is added to books uploaded from Internet Archive (and others) which should also be removed. Ciridae (talk) 13:57, 8 January 2026 (UTC)Reply

@Enyavar The tool should no longer break templates when removing {{Book}}. However I gather that's not fully what is wanted here. Its not fully clear to me how the tool should act when a book template is present, since for example, File:Andrees Handatlas - Haiti und Puerto Rico.jpg does not have all the fields of the information template. Currently the tool can only delete templates but not interpret them, so having it convert {{Book}} to {{Information}} might be quite a bit of effort. Bawolff (talk) 05:16, 6 February 2026 (UTC)Reply

@Bawolff: Yes, converting Book template to Information template is what we're looking for. Also, the PDF or DJVU templates should also be removed, if present. Ciridae (talk) 06:42, 20 February 2026 (UTC)Reply

Hi, I just noticed this conversation after posting a comment on Issue #2. I've been slowly trying to clean up Category:Pages using Information template with parsing errors, but new entries are added to that category by the tool somewhat regularly. A recent example I fixed was File:Le Pâtissier Royal Belge - 1922 (page 221 crop).jpg (diff). There are 6 or 7 more crops I plan to fix from yesterday. More examples can be seen in my recent contributions.

While I'm not 100% familiar with the rationale of preferring the Information template over the Book template over such crops, my preference would be that the tool is able to either migrate the template in its entirety or not at all. If it doesn't then it'll end up in Category:Media missing infobox template which is not great but better than having a broken template IMO. If the cause of what's breaking these templates could be identified, I'd be much obliged. --Stux (talk) 15:14, 4 March 2026 (UTC)Reply

Just as a note, that example is with croptool1 not croptool2. Croptool2 should now take the do not migrate the template at all approach currently. Bawolff (talk) 15:34, 4 March 2026 (UTC)Reply

@Bawolff: , ah that makes more sense. Thank you for clarifying that. I had not noticed the tag that says "CropTool 1.5". I'm surprised that's still around. I thought the only way to use the current croptool was using the Gadget? How is the old version still accessible? And is there a reason it's still popular? Are the features and/or behavior that different? I'm still seeing new edits with this version producing images with broken templates. So I'm wondering what incentives there might be to using the old tool or switching to the new one. --Stux (talk) 18:55, 7 March 2026 (UTC)Reply

Basically the original author wasn't responding so i forked the tool and called it croptool2. The original is still out there. You can use it by going directly to its url. Possibly some people use their own userscripts for the integration instead of the gadget, which may point to the other version. Bawolff (talk) 19:09, 7 March 2026 (UTC)Reply

I see now. Got it. Thanks for the explanation, Bawolff! --Stux (talk) 16:34, 8 March 2026 (UTC)Reply

For what it's worth, you can't really usurp/supersede the original tool per the right to fork policy.

Sorry, I read COM:CROP briefly and assumed this would fit the ‘minor changes and implements section’, specifically a minor crop, and I’ve had my own uploads cropped and overwritten so I assumed this was standard practice. SnowyRiver28 (talk) 18:49, 22 October 2025 (UTC)Reply

They were made with previous accounts some years ago I believe, but that’s beside the point. Would this consist of a ‘major crop’ in the eyes of COM:CROP and therefore warrant making a new file? SnowyRiver28 (talk) 03:07, 23 October 2025 (UTC)Reply

@SnowyRiver28: it is hard to imagine any desirable minor crop that would be an appropriate overwrite of that file. It has no unneeded borders; the horizon line seems unproblematic; it is reasonably well composed. It seems to me that if you want a version that is differently cropped, it should not be an overwrite. What exactly do you have in mind? - Jmabel ! talk 18:06, 24 October 2025 (UTC)Reply

The grey cursor is hardly visible out of the cropped area, i cannot attach a screenshot, because the screenshots don't show the cursor as I see it.

Clearly related to #Broken templates in cropped images and removing {{Book}}. It's obvious that the current state is not a correct solution. - Jmabel ! talk 19:08, 20 February 2026 (UTC)Reply

Ok, book template is no longer being removed (e.g. File:Charles Lloyd by John Constable (page 276 crop).jpg). Bawolff (talk) 18:33, 22 February 2026 (UTC)Reply

For the longer term, we can probably do better than the status quo, but i dont think there is any solution where users never have to update file description pages after cropping in all cases. Bawolff (talk) 18:36, 22 February 2026 (UTC)Reply

I usually set new categories after cropping, so yes, I see it's necessary to manually update the page because cropped content is not the original content.

I just don't think that it is really feasible to tell users "return to the original file; copy out the whole description page; return to the cropped file; input the description you copied; carefully study the various used description templates to change the file description to match the new content; oh and be careful to not disturb the extraction-templates that link the files together."

Thanks for preserving the book template in the future, I hope we can fix the broken templates from images that were cropped in the meantime. --Enyavar (talk) 14:11, 24 February 2026 (UTC)Reply

I get [Error] undefined at the preview stage on large png files like https://commons.wikimedia.org/wiki/File:Whistler_-_Symphony_in_Blue_and_Pink,_ca._1868,_F1903.179a-b.png I get no error for similarly sized jpg files. Surajr7 (talk) 04:28, 4 March 2026 (UTC)Reply

Hum, works for me. Does it say CropTool2 in the left upper corner when you load the original image? Doc James (talk · contribs · email) 21:35, 8 March 2026 (UTC)Reply

So apparently I have to recrop photos using this tool but the tool isn't showing up like it says it should. So now what? MoonsMoon MoonsMoon 00:16, 5 March 2026 (UTC)Reply

It is now right upper corner under the tools dropdown. Doc James (talk · contribs · email) 00:32, 5 March 2026 (UTC)Reply

Nope, not there either. And when I use the other outside link thing it says to try, it picks and chooses when it wants to work. MoonsMoon MoonsMoon 00:35, 5 March 2026 (UTC)Reply

@MoonsMoon Have you check if you have enabled "CropTool" in your preferences? It should be enabled after you clicked "Activate CropTool!" in Commons:CropTool#Setup. Thanks. Tvpuppy (talk) 01:44, 5 March 2026 (UTC)Reply

Additionally, if you open the web developer console (f12), are there any errors? Bawolff (talk) 04:38, 16 March 2026 (UTC)Reply

It still never showed up. I have to go to the tool's page to do it. But now when I crop a photo, it doesn't change the cropped file's name so it still shows up as the original. Its really very stupid. This is the cropped version - https://commons.wikimedia.org/wiki/File:Khmer_silks.jpg

But because the stupid thing suddenly won't change the file name, I can't replace it on the page. It still shows up as not cropped - https://en.wikipedia.org/wiki/Sampot#Textiles MoonsMoon MoonsMoon 04:09, 28 March 2026 (UTC)Reply

@MoonsMoon: It looks to me like you have done an inappropriate overwrite of File:Khmer clothing (female and male).jpg (twice, actually), probably by choosing "Overwrite" in the Croptool preview, rather than "Upload as new file". It no longer has any relation to its title. It's your upload, so I'm not reverting it (you should feel more than free to do so), but it is as if you are vandalizing your own file.

Also, this file has no categories.

BTW, did you try what Bawolff suggested about the web developer console? Were there any possibly related errors? (In my experience, there are almost always some errors in the console; you made no mention of what you saw.) And using the "Inspector", does the string "⌗ CropTool" show up anywhere in the HTML? - Jmabel ! talk 05:08, 28 March 2026 (UTC)Reply

I am having this exact same issue. The tool doesn't appear under the tools dropdown, and when i use the "Alternative: go to tool forge", it keeps displaying an error message when i input the commons file i am trying to crop. Ifedohlapo (talk) 10:18, 6 March 2026 (UTC)Reply

@Ifedohlapo: What error message? — 🇺🇦Jeff G. ツ please ping or talk to me🇺🇦 11:00, 6 March 2026 (UTC)Reply

It says "Unauthorized" Even though I have gone through the authorization process, and it shows Authorized at the top right corner Ifedohlapo (talk) 15:06, 6 March 2026 (UTC)Reply

Hi. When undertaking this crop, it did not populate the new file with the original file's information and Flickr license. It only populated with the "Extracted from" template. The license was added manually here, otherwise the file would have been deleted. Has something changed with how the crop tool works? I have used it before where it has worked as intended – see here. Thanks. DaHuzyBru (talk) 04:50, 13 March 2026 (UTC)Reply

Thanks, we will look into this. User:Bawolff. Doc James (talk · contribs · email) 06:58, 13 March 2026 (UTC)Reply

Comment, I also came across the same problem with this crop, which the file information and license templates were not copied from the source image. Thanks. Tvpuppy (talk) 18:19, 2 April 2026 (UTC)Reply

I have just successfully used CropTool to make an image from the first page of File:Report On The Derailment which occurred on 23rd January 1955 at Sutton Coldfield.pdf; but if I try to use it on pages 21 or 22 of that work (very large plates), if hangs, and I am logged out (from the tool not Commons). Can anyone advise? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 12:42, 13 March 2026 (UTC)Reply

@Pigsonthewing: The timeout probably needs to be tweaked. Can you do it otherwise using another tool from Commons:Extracting images from PDF#Extracting images from PDF? — 🇺🇦Jeff G. ツ please ping or talk to me🇺🇦 13:10, 13 March 2026 (UTC)Reply

Yes, I did the job on a downloaded version on my machine.

But why does a timeout log me out, rather than just returning an error message? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 14:14, 13 March 2026 (UTC)Reply

@Pigsonthewing: The last version I heard on a different platform was to save limited quantities of sessions or sockets for only those users actively using them, preserving availability for the next request. One system I use times out after as few as two minutes, which is exceedingly annoying when tracking the GPS of a vehicle which only reports every two minutes. — 🇺🇦Jeff G. ツ please ping or talk to me🇺🇦 14:38, 13 March 2026 (UTC)Reply

It seems that you clicked overwrite instead of upload as new file. GPSLeo (talk) 14:56, 3 April 2026 (UTC)Reply

@GPSLeo: My goal is to upload a new version of the file, not to save new file. Since "Overwrite" is an option, could you please help me understand why my attempt is triggering an abusefilter? GoingBatty (talk) 15:54, 3 April 2026 (UTC)Reply

I do not see why overwriting should be fine and comply with the COM:OW guideline here. GPSLeo (talk) 16:27, 3 April 2026 (UTC)Reply

@GoingBatty: Hi. I am sorry to inform you that you have triggered Special:AbuseFilter/290 many many times over the past 2+ years. The proposal to "Limit file overwriting to users with autopatrol rights" was accepted with many supports and one weak oppose 15:19, 23 September 2023 (UTC). After an implementation problem in phab:T345896 and testing, Special:AbuseFilter/290 went live with the Disallow action 09:35, 28 October 2023 (UTC). Please read MediaWiki:abusefilter-warning-file-overwriting. You may request COM:AP at COM:RFR when you think you are ready (now that you have made more than 500 useful non-botlike edits); having that should allow you to overwrite. Also, please think twice about cropping any file that is missing evidence of permission. — 🇺🇦Jeff G. ツ please ping or talk to me🇺🇦 16:40, 3 April 2026 (UTC)Reply
