The tightest compression among modern formats — fewer bytes at the same quality.
- Your file never leaves your device — the server never receives or sees it.
- AVIF usually produces the smallest file among JPG/PNG/WebP/AVIF at the same quality.
- Transparency is preserved — AVIF handles an alpha channel, same as WebP and PNG.
How it works
Choose an image
JPG, PNG, or WebP — drag a file in or open it with the button.
Pick a quality level
The slider sets the quality; the exact file size appears when you tap the button — AVIF isn't estimated automatically.
Download the AVIF
The finished file saves straight to disk, no server queue involved.
