- Quick photo retouching, resizing, cropping, and color correction.
- Layered editing with blend modes, text layers, and non-destructive changes.
- Batch editing, renaming, and converting multiple images at once.
- Filters and effects: noise removal, sharpen, artistic, blur, and more.
Key Features
- 200+ tools, adjustments, and effects in a lightweight portable app.
- Layers, color management, and wide format support (PSD, camera RAW, and more).
- Batch processing and macro recording for repeated tasks.
- Free, open-source (BSD), and works offline from a USB stick.
Pros & Cons
Pros: tiny and portable, genuinely free and open source, surprisingly full-featured, great for quick edits. Cons: Windows only, less advanced than heavyweight suites for professional retouching, some tools have a learning curve.
