Supported formats
Input
Output
WebP
Great balance between quality and size for the web.
PNG
Near-lossless; quality controls compression.
JPEG
Ideal for photos; quality heavily affects file size.
ICO
Useful for icons, with multiple internal sizes.
SVG
Generates an SVG with the image embedded as PNG base64.
Quick tips
- WebP ~80–90% — solid default for the web
- JPEG ~75–85% — good balance for photos
- PNG — when you need transparency or less loss
- ICO — app or site icons
- SVG — vector container with an embedded bitmap (tends to get larger)
