GIMP 2.10.32 Released

GIMP continues strengthening its bases as this new version 2.10.32 is quite heavy on bug fixes and improves our support for many image file formats.

This news lists the most notable and visible changes. In particular, we do not list here the bug fixes. To get a more complete list of changes, you should refer to the NEWS file or look at the commit history.

File Formats


GIMP now supports 8 and 16-bit CMYK(A) TIFF files on import. This is one of the first consequences (already!) of the GSoC project by NikcDC under mentorship of Jehan.

Moreover the BigTIFF format is now supported, both for import and export. BigTIFF is an evolution of the original TIFF format allowing files bigger than 4GiB by using 64-bit internal offsets.

The TIFF export dialog exposes a checkbox to enable this format variant.

Moreover, if you try to export as a TIFF file and if it fails because of the maximum file size being exceeded, it will propose you to retry either as BigTIFF or with another compression algorithm.

Finally additional special cases in TIFF format are now taken into account, making loading TIFF files more robust.


JPEG XL file format has been supported in development code ever since GIMP 2.99.8.

Daniel Novomeský backported the import code to the stable branch.

We remind that a third-party plug-in already exists, by developers of the libjxl library. It is a different codebase and should still work with GIMP 2.10.32. The main advantage of the third-party plug-in is that it has also export capabilities (which our stable plug-in doesn’t have yet), though with some unsolved issues causing some images to fail to load or export correctly.

You are welcome to continue using the third-party plug-in if you prefer. For instance the MSYS2 project now has it built-in within the libjxl package. If you install it, it will take precedence over our new core plug-in.


Some game engines require DDS images to be flipped vertically. Until now, asset creators had to flip the image in GIMP, export, then undo, which was not a very practical workflow.

This is why NikcDC added a new “Flip the image vertically on export” option allowing you to flip your image at export time.

Similarly, there is now a Visible layers” option (additionally to “Selected layer“, “As cube map“…) allowing you to export the whole image render, not a single layer. So depending on your work usage, you won’t have to flatten your image (to later undo this action) anymore before export.

Metadata handling (PSD…)

Several metadata handling improvements were made. One of the most important changes is that GIMP will start dropping Xmp.photoshop.DocumentAncestors tags if more than a thousand of them are found.

This case is very likely due to a bug in some versions of Photoshop or other software creating PSD files as we encountered over 100,000 such tags in some files (it probably makes no sense that a document could have that many ancestor documents), which was seriously slowing down GIMP to the point it looked frozen.


XCF import code also received various improvements, making the software more robust to invalid files. In some cases, it allows to salvage more data from corrupted XCF files, hence protecting your work.

Other formats

More format handling were improved:

A new PDB procedure file-bmp-save2 was added for plug-in developers. It supports all the options available interactively.
Fixed endian conversion for photometric interpretation MONOCHROME1.
Loading transparent EPS files is now supported.
RGB Save Type” confusing dialog label renamed to “Palette Type” as on the main dev branch.
Improved support of indexed images with alpha channel (both import and export).
Export has a new IPTC checkbox (saved through XMP) as well as a thumbnail checkbox. (backported from dev branch, since 2.99.8)

Text tool: localized glyph variants

The Text tool now supports localized glyphs (locl) depending on the value of the “Language” tool option.

It is useful if you write in languages with regional variant forms (e.g. Serbian or Ukrainian use the same Cyrillic alphabet yet with 5 letters having regional variants).

If your chosen font supports several variants, you can now tell the internal formatting system through the “Language” settings which one needs to be used.

All these changes are works by Stanislav Grinkov.

Improved Screenshot on Windows

The Screenshot plug-in was missing the “Include mouse pointer” option on Windows.

This long missing feature, which was available on other platforms (such as Linux X11/Wayland, *BSD or macOS) is now implemented on Windows as well!

GEGL, babl

GIMP 2.10.32 is the first stable release with the nice optimizations brought since babl 0.1.90 and GEGL 0.4.36, now that they have been battle-tested and debugged within the development release GIMP 2.99.10. As a consequence, babl 0.1.92 has been released, fixing in particular SIMD discovery ability, which was misbehaving on Windows.

These improvements are important enough that we felt their 2.99.10 description deserved to be copied on the stable news to make clear this applies to GIMP 2.10.32 now.

Automatic LUT creation for conversions in babl

Citing Øyvind in a recent report:

babl works as a universal pixel encoding translator by having - a not necessarily fast reference conversion able to deal with everything - and a collection of conversions that can be chained together into what babl calls fishes. The fishes are raced against each other to find the best conversion babl is able to create.

In some situations, a LUT (Look-Up Table) will perform better, we now know what the performance will be of using a LUT for various combinations of input and output bits per pixel; and mark fishes that are better as LUTs on creation time. If such a fish is used more than a minimum, LUT population is triggered.

Right now one drawback is that it might actually slow down slightly the first conversion happening in a given input > output conversion couple. The solution which might come later would be to create the LUTs in the background in a thread and continue doing non-LUT conversions until it is ready.

Note that the created LUTs are also garbage-collected after a few minutes of non-usage, to avoid filling memory with single use LUTs.

SIMD builds for x86_64 and ARM neon (ctx, babl and GEGL)

All of babl, GEGL and ctx have gotten similar SIMD build and dispatch changes applied.

Image processing code written to be portable and performant caters well to the auto-vectorization support for SIMD in modern compilers. The way it is done is mostly by changes to the build system. For now the code remains the same for all targets but the approach can be extended with conditional intrinsics.

To see the impact this can have, here is a test of filling a circle with ctx and its different pixel encoding targets, on a Raspberry Pi with default compiler flags (without neon support). Note that the cairo reference comparison is the BGRA8 format (the only other format proposed by Cairo is A8):

Test results without SIMD
Filling a 256px radius circle in a 512x512 buffer a number of times without Neon (smaller is better)

And the same test, with the compiler allowed to use Neon instructions:

Test results with SIMD
Filling a 256px radius circle in a 512x512 buffer a number of times without Neon (smaller is better)

Note well that both the optimized and non-optimized cases are built-in, and availability of relevant instructions determined by runtime tests. This makes these optimizations very portable, despite being based on recent architecture instructions.

ℹ️ Note that these changes (both the automatic LUT generation and the SIMD dispatch) will apply to GIMP 2.10 versions later. For now they are available in 2.99 as a form of beta test. We welcome feedbacks if you encounter any misbehavior.

Other improvements

babl now also comes with pre-defined CIE Lab u8 and CIE Lab u16 formats.

Team news

lukaso was already considered co-maintainer of the macOS build repository of GIMP (gimp-macos-build) since they have done most heavy lifting on GIMP for macOS for many months. This has been made official by changing their account to maintainer on this build repository.

Lloyd Konneker has been given developer git access to the main GIMP repository, in particular for their nice work so far on script-fu (which was in a state where dropping script-fu for GIMP 3.0 would have been considered otherwise).

Kevin Cozens, a long term GIMP contributor and script-fu maintainer got back recently and was given git access again to the repository. He will help co-maintain script-fu with Lloyd.

Ondřej Míchal has been given “Reporter” rights on the main GIMP repository (allowing to triage reports: labelling, closing, reopening, and moving reports…).

After being given “Reporter” rights initially, NikcDC has eventually been given developer git access in order to facilitate the work on feature branches for their GSoC project.

Around GIMP

Mirror news

Ever since our new official mirror procedure, the following mirrors have been added to our rotation scripts:

  • Get Hosted Online (Rothwell, United Kingdom)
  • Aceldama Systems (Montreal, Canada)
  • Open Computing Facility (Berkeley, CA, United States)
  • Freedif (Singapore)

One mirror from the previous list had to be removed because of performance issues, and a mirror acceptance is still on-hold because of the conflict and unstability in East Europe.

As a fun note, GIMP is now back to Berkeley through the Open Computing Facility (student organization for all University of California, Berkeley students, faculty, and staff). For anyone wondering why it’s fun, you may read with interest the birth story of the GNU Image Manipulation Program.

TLDR; GIMP was originally born in the University of California. I guess it’s good to be home, right?

Book news

Our books page was in a badly maintained state. 4 books in Spanish were added to the list recently:

We took the opportunity to restructure the page with per-language section.

This is also a good time to remind that it is up to everyone to help us keep this page updated. We know many more books have been published about GIMP across the years so the list is very incomplete. Therefore if you wrote or know of a book absent from the page, please feel free to report the same information as other books on the page so that we can add them. Thanks!

Downloading GIMP 2.10.32

As usual, GIMP 2.10.32 is available on GIMP official website ( in 3 package formats:

  • Linux development flatpak
  • Windows installer
  • macOS DMG package

Other packages made by third-party are obviously expected to follow (Linux or *BSD distributions’ packages, etc.).

What’s next

You may notice that stable releases are slowing down (GIMP 2.10.30 happened 6 months ago) as we are reaching a good stability overall on this branch, despite being held back by our very old toolkit. Nowadays most of our focus is on the development branch. Yet we will continue to provide updates and bug fixes to the 2.10 branch until GIMP 3.0 is out.

Don’t forget you can donate to the project and personally fund several GIMP developers, as a way to give back and accelerate the development of GIMP. As you know, the maintainers of GEGL and GIMP are crowdfunding to be able to work full-time on free software. 🥳
