Free photo editing apps for Mac let you adjust colors, crop, retouch and export photos without paying for Adobe Photoshop. The free options have gotten very good. For most users, you never need to pay for editing software unless you do this for a living.
Tested most of the free Mac photo editors recently. Some are surprisingly close to paid software. Some are too limited to recommend. The list below sticks to the ones worth installing in 2026.
Apple Photos
Apple Photos is free, built into every Mac. Most people underestimate it. The editing tools are solid for most everyday needs. Auto-enhance works genuinely well. Color, light, retouching and filters all hit reasonable quality.
The biggest strength is integration. iCloud sync with iPhone Photos means you can edit on either device and changes flow both ways. The biggest limit is no layer support, which means complex composite editing is off the table. For photo touch-ups and color work, it covers 80% of what most users need.
Here is what Apple Photos offers:
| Feature | Details |
|---|---|
| Pricing | Free, built into macOS |
| Auto-enhance | Genuinely good one-click fixes |
| Layers | No |
| iCloud sync | Yes, with iPhone Photos |
| RAW support | Limited compared to dedicated tools |
| Best for | Casual editing of family and travel photos |
GIMP
GIMP is the most powerful free photo editor. Open source. Been around 20+ years. Equivalent to Photoshop for most users. Layers, masks, filters, plugins, custom brushes. If you can do it in Photoshop, you can probably do it in GIMP.
The interface feels dated compared to modern apps. Steeper learning curve than Photopea or Apple Photos. But for users who want a real Photoshop alternative without paying Adobe $23/month, GIMP delivers. The community support and tutorials are massive.
Here is what GIMP delivers:
| Feature | Details |
|---|---|
| Pricing | Free forever, open source |
| Layers and masks | Full support |
| Filters and plugins | Hundreds available |
| Interface | Functional but feels dated |
| Learning curve | Moderate to steep |
| Best for | Power users wanting Photoshop alternative free |
Photopea
Photopea runs entirely in your browser. Looks and works like Photoshop. Opens PSD files natively. Saves to PSD, JPG, PNG, SVG. The free version has ads in the sidebar. $5/month removes them.
The big advantage is zero installation. Works on M1, M2, M3 Macs natively in Safari or Chrome. No updates to manage. No disk space used. Performance is slower than native apps but the features are genuinely Photoshop-class.
Here is what Photopea offers:
| Feature | Details |
|---|---|
| Pricing | Free with ads, $5/mo to remove |
| Installation | None, runs in browser |
| PSD support | Yes, native |
| Performance | Slower than native, fine for most edits |
| Best for | Users who need Photoshop occasionally without paying |
Darktable
Darktable is a free Lightroom alternative focused on RAW processing and library management. Non-destructive editing means your original files stay untouched while you experiment. Designed for photographers who shoot a lot.
The learning curve is steeper than most apps on this list. The reward is professional-grade RAW processing that rivals Lightroom for free. Photographers love it. Casual users find it overwhelming.
Here is what Darktable delivers:
| Feature | Details |
|---|---|
| Pricing | Free, open source |
| RAW processing | Professional grade |
| Non-destructive | Yes, all edits are reversible |
| Library management | Strong organization tools |
| Best for | Photographers who shoot RAW regularly |
RawTherapee
RawTherapee is another free open source RAW processor. Less famous than Darktable but equally capable. Some photographers prefer it for specific RAW conversion workflows.
The Mac version sometimes lags behind Linux and Windows builds. Still good. Just check release dates if you want the latest features.
Krita
Krita is built primarily for digital painting but also handles photo editing well. The brush engine is the strongest of any free app. Layers, masks, color tools and a clean interface.
If you also draw or paint digitally, Krita does double duty. For pure photo editing without artistic painting needs, GIMP is more focused.
Pixelmator Pro (Paid but Worth Mentioning)
Pixelmator Pro is the best paid photo editor for Mac. $49.99 one-time (sometimes $29.99 on sale). Free trial available. Apple Silicon optimized. ML-based smart tools.
For users who feel limited by GIMP’s dated interface but do not want Adobe’s subscription, Pixelmator Pro fills the gap. Use the free trial to test before paying.
Use Cases by Editor
Different editors fit different needs. Here is the quick guide to picking based on what you actually do with photos.
- Quick fixes and family photos: Apple Photos (built in).
- Layer-based editing and composites: GIMP or Photopea.
- RAW photography workflow: Darktable or RawTherapee.
- PSD file support: Photopea (opens and saves PSD natively).
- Digital painting plus photo edits: Krita.
- Best paid option with free trial: Pixelmator Pro.
What to Avoid
Mac App Store has plenty of photo editing apps that look promising but become subscription traps. Watch out for these patterns.
- Apps that demand subscriptions for basic edits like crop and brightness.
- Free apps that watermark every export until you upgrade.
- Apps with vague developer names and no clear website.
- Apps charging weekly subscriptions (almost always scams).
- Apps that only export at low resolution unless you pay.
Our Pick
For most Mac users, Apple Photos plus Photopea for occasional advanced work covers everything. Both totally free. Apple Photos handles 80% of edits. Photopea handles the rest including PSD files. Skip GIMP unless you specifically want desktop power tools.
For serious photographers shooting RAW, Darktable is the free Lightroom alternative. For digital artists who also edit photos, Krita is the dual-purpose pick.
Final Thoughts
Best free photo editing apps for Mac in 2026 are Apple Photos for casual edits, GIMP for power users, Photopea for browser-based PSD work, Darktable for RAW photographers and Krita for digital artists. Most people do not need to pay for editing software unless this is their job. Free tools cover the rest. Try Apple Photos first since it is already installed.
