The free and open-source image editing world has been eagerly anticipating a major update, and that wait is finally over. After seven years of development, GIMP 3.0 has arrived, bringing substantial improvements to what many consider the premier free alternative to commercial image editing software.
A Complete Interface Overhaul
The GNU Image Manipulation Program (GIMP) team initially focused on overhauling the user interface for version 3.0, transitioning from GTK2 to GTK3. This update delivers significantly improved UI scaling for HiDPI displays, addressing a common pain point in version 2.10. The new interface also features better dark theme support, mouse wheel navigation between dockable dialogs, and improved tablet support. GIMP 3.0 now runs natively on both Wayland and X11, providing more flexibility for Linux users with different display server preferences.
Key Features in GIMP 3.0
- GTK3-based user interface with better HiDPI support
- Non-destructive layer effects
- Enhanced color space management
- Multiple layer, channel, and path selection
- Off-canvas editing with auto-expanding layers
- Expanded file format support
- New Welcome Dialog with quick preference settings
- Improved tablet input support
Non-Destructive Layer Effects
Perhaps the most significant functional improvement in GIMP 3.0 is the introduction of non-destructive layer effects. Previously in GIMP 2.10, filters were automatically merged onto layers, making further adjustments difficult without undoing previous work. Now, filters remain active by default after being applied, allowing users to re-edit most GEGL filters directly from the layer dockable without reverting their work. Users can toggle filters on or off, selectively delete them, or merge them down when desired. For those who prefer the traditional workflow, a Merge Filters option is still available.
Enhanced Color Management
GIMP 3.0 brings more extensive support for RGB color spaces beyond sRGB. Images loaded with specific color profiles, such as AdobeRGB, retain that information throughout the editing process. This improvement extends across various dialogs, including the Colors dockable window, the Foreground and Background selection dialog, and the Color Picker info window. Color simulation and soft-proofing have also been enhanced, with consolidated options available in a pop-over menu at the bottom-right corner of the status bar. These improvements lay the groundwork for future CMYK and LAB image color mode support.
Workflow Improvements
Multiple usability enhancements make GIMP 3.0 more intuitive and efficient. Users can now select multiple layers, channels, and paths simultaneously, eliminating the need to manually link items. Layer locks have been moved to a more accessible location next to each layer's visibility icon. A new layer set feature helps with organization, and users can search for layers by name within large projects. The paint tools now support off-canvas editing, automatically expanding layer dimensions as you draw beyond their boundaries.
File Format Support
GIMP 3.0 expands its compatibility with various file formats. Icon designers will appreciate support for macOS ICNS icons and Windows CUR and ANI cursors. The software now handles Amiga ILBM/IFF formats, newer formats like QOI and JPEG XL, and provides import support for older formats such as DCX, PAM, and WBMP.
New Welcome Dialog and Customization Options
A new Welcome Dialog greets users upon startup, providing quick access to create or load images and adjust key preferences. Users can choose between Symbolic, Color, or Legacy icon styles; select Light, Gray, or Dark UI themes; enable Tool Groups to condense toolbox icons; and merge menu toolbars for a more streamlined interface.
Future Development Plans
While GIMP 1.x lasted eight years and GIMP 2.x reigned for 20 years, the development team plans to accelerate the release cycle for version 3.x. Users can expect GIMP 3.2 within a year, with more frequent but potentially smaller feature updates. The team is also encouraging community participation in the UX Design group to help shape the future look and feel of the software.
Development Timeline
- GIMP 1.X: 8 years
- GIMP 2.X: 20 years
- GIMP 3.X: Planned for more frequent updates (GIMP 3.2 expected within a year)
Availability
GIMP 3.0 is available now for GNU/Linux and Windows platforms. Mac users should note that the current macOS package still provides GIMP 2.10.38, with the 3.0 update expected to follow soon. As with previous versions, GIMP remains free software, allowing users to modify the source code and distribute their changes.
