10 Open-Source Image Editors and Tools in 2026, by Task

“Best open-source image editor” depends on whether you are retouching pixels, painting, developing RAW files, designing vectors, or automating conversions. This is a task-based shortlist, not a claim that one program wins every category. The tools below have different workflows, so check the linked project pages for current releases and supported systems.

General raster editors

1. GIMP — A mature general-purpose editor for raster painting, retouching, compositing, and file conversion. Its 3.x releases add non-destructive filters and improve text and color workflows; check current release notes for the latest stable version.
2. PhotoCraft — An early-alpha, Rust-based layered editor with masks, adjustments, text, shapes, filters, and PSD support. Choose it to follow an active project or explore its current workflows; do not assume it replaces a mature production pipeline. Read the PhotoCraft review.
3. Pinta — A simpler free and open-source bitmap editor for drawing and straightforward image edits. It can be a more approachable choice for basic tasks when you do not need the breadth of a large compositor.
4. LazPaint — A cross-platform editor with raster and vector layers. It is another option for a compact desktop editing workflow; check its downloads for your operating system.

Painting and illustration

5. Krita — A free, open-source digital painting program. It is a strong fit for illustration and painting tasks where brush tools and tablet use are central.
6. MyPaint — A focused painting app with configurable brushes, an infinite canvas, and graphics-tablet support. It is oriented toward painting rather than broad photo compositing.

Photography and RAW

7. darktable — A non-destructive photography workflow and RAW developer with image-library management. Choose it to develop camera files and manage a photo workflow, not as a direct substitute for every layer-based edit.
8. RawTherapee — A free, cross-platform RAW processor with non-destructive processing. It fits detailed camera-RAW development and exports edited images for other uses.

Vectors and automation

9. Inkscape — A free and open-source vector graphics editor based around SVG. It is suitable for logos, diagrams, and scalable illustration, but vector design is not the same as pixel retouching.
10. ImageMagick — A command-line image-processing suite for conversion, resizing, compositing, and batch workflows. It is useful for repeatable automation, not a GUI-first photo-editing session.

How to choose

If you need a general desktop raster editor, compare GIMP and PhotoCraft. For painting, try Krita or MyPaint; for camera RAW, compare darktable and RawTherapee; for vector artwork, use Inkscape; and for scripted processing, evaluate ImageMagick. Review file compatibility, license terms, and export behavior before moving a project.
