This tool processes selected files in your browser.

Accepted: image/png, image/jpeg, image/webp, image/avif, .png, .jpg, .jpeg, .webp, .avif. Desktop cap 30 MiB per file.

A canvas MIME fallback is treated as unsupported, not as AVIF.

How it works

  1. Choose PNG, JPEG, WebP, or AVIF files.
  2. To AVIF encodes 8-bit libavif. From AVIF writes PNG.
  3. Download a new file. Canvas WebP/PNG is never labeled as AVIF.

Files stay in this tab. No upload.

10-bit is not in this pack. HEIC is a different, unsupported codec.

Supported inputs and outputs

PNG/JPEG/WebP/AVIF in. image/avif or image/png out.

Example

An 8×8 PNG exported as AVIF reopens with ftyp avif.

Questions and answers

Is a renamed JPEG AVIF?

No. The encoder writes a real AVIF and reopens it.
