Notes
- PNG, JPEG and WebP are encoded by your browser. GIF, BMP, TIFF and ICO use our own encoders; AVIF encoding depends on browser support and falls back to WebP when unavailable.
- Transparency survives in PNG, WebP, AVIF, GIF (1-bit), TIFF and ICO. JPEG and BMP flatten it onto a background colour you can choose.
- Everything runs locally in your browser; your images are never uploaded to any server.
