What it is
GIMP (GNU Image Manipulation Program) is the most widely used free, open-source image editor — the main alternative to Adobe Photoshop. It’s used for photo editing, retouching, compositing (combining images), creating web graphics, and digital artwork.
Unlike vector tools (Inkscape, Illustrator), GIMP works with raster graphics — images made of pixels, like photos.
GIMP + AI (mid-2026):
- GEGL (Generic Graphics Library): GIMP’s underlying processing engine includes a variety of AI-assisted filters — noise reduction, sharpening, upscaling
- G’MIC plugin (free): A powerful third-party filter collection that includes AI-based denoising, face enhancement, and style transfer effects. One of the most feature-rich free AI additions to any open-source tool.
- Stable Diffusion integration: The GIMP Stable Diffusion plugin (community; free) brings AI image generation directly into GIMP — generate images or inpaint (fill in selected areas) using AI without leaving GIMP
- AI upscaling: Via G’MIC or separate tools like waifu2x/Real-ESRGAN that can be called from GIMP scripts
What you’d use it for
- Editing photos: cropping, colour correction, brightness/contrast, removing blemishes
- Creating website graphics and social media images
- Photo retouching and compositing (combining multiple photos)
- Digital painting and illustration
- As a free alternative to Photoshop for most everyday photo editing tasks
How to get started from Australia
- Go to https://gimp.org/downloads → Download for Windows, Mac, or Linux
- Install and open → you’ll see a floating toolbox and canvas
- File → Open to open a photo
- Use the tools on the left to: Crop (rectangle select → Crop), Heal (Heal tool — removes blemishes), Brightness-Contrast (Colours menu)
- For AI features: install G’MIC (gmic.eu) → it appears under Filters → G’MIC
Tutorial resources: GIMP’s own documentation (docs.gimp.org); YouTube is extensively covered.
How it compares to alternatives
| Tool | Cost | Best for |
|---|---|---|
| GIMP | Free | Open-source photo editing; all platforms |
| Adobe Photoshop | ~$40 AUD/month | Industry standard; professional workflow |
| Affinity Photo | ~$80 AUD one-time | Professional quality; no subscription |
| Pixelmator Pro | ~$75 AUD one-time (Mac) | Mac-native; ML features; easier than GIMP |
| Canva | Free/paid | Quick edits; non-designers |
| Photopea | Free (web) | Browser-based Photoshop alternative |
For non-professionals who want photo editing without subscriptions, Affinity Photo or Pixelmator Pro are more user-friendly than GIMP, at a one-time cost. GIMP is the best choice if you need it completely free or cross-platform.
Gotchas
- Notoriously unintuitive interface. GIMP’s interface was not designed with modern UX principles. Many tasks that are obvious in Photoshop require hunting through menus in GIMP. The single-window mode (enable via Windows → Single-Window Mode) is much better.
- No CMYK colour support natively. GIMP works in RGB. For print work requiring CMYK output, professional tools (Photoshop, Affinity Photo) are necessary.
- 16-bit and 32-bit support is improving but the workflow for high-dynamic-range (HDR) photography editing is less mature than Photoshop.
- AI features require plugin installation. The AI Stable Diffusion plugin and G’MIC both require manual installation — not built-in.
