AVIF to PNG

Files never leave your device

Drop AVIF files here to get PNGs with transparency kept, ready for editors and design tools that do not read AVIF.

How to use it

  1. Drop .avif files or choose them.
  2. Each file converts as it arrives.
  3. Download the PNGs or a zip.

Details

Input
AVIF (still images, with alpha)
Output
PNG with alpha, 8 bits per channel
Needs
A browser that decodes AVIF (all current major browsers)
Limits
No file count limit. Very large images (above ~16,000 px on a side, or ~250 megapixels on phones) can exceed the browser's canvas limit.

Questions

Are my files uploaded?

No. The page loads its code once, then reads and processes your files inside the browser tab. Nothing is sent to a server; you can confirm it in your browser's network panel while a file converts.

Why is the PNG so much larger?

AVIF is one of the most efficient image formats; PNG is lossless. A 10–20× size increase is normal for photos. Choose AVIF to JPG if size matters and you do not need transparency.

Are HDR or 10-bit AVIF files kept as HDR?

No. The browser canvas works at 8 bits per channel, so the PNG is standard dynamic range.
