How it works

AVIF Converter in 4 steps

  1. Choose an AVIF, JPG, PNG, or WebP image.

  2. Select AVIF, JPG, PNG, or WebP output.

  3. Set the quality level for compressed formats.

  4. Convert and download the locally generated result.

When to use it

Open AVIF files and convert them to broadly compatible JPG, PNG, or WebP, or encode an existing image as modern AVIF. A local libavif WebAssembly codec handles decoding and encoding with adjustable quality and exact before-and-after file sizes.

  • Open an AVIF image in software that only accepts JPG or PNG.
  • Create smaller AVIF website assets from JPG or PNG sources.
  • Compare AVIF file size against WebP or JPG at a chosen quality.

Format & quality notes

  • AVIF encoding is CPU intensive and can take several seconds for large camera images.
  • PNG output is lossless; JPG does not support transparency.
  • The codec runs as WebAssembly and never uploads the image.
FAQ

Questions about the AVIF Image Converter.

Can I convert AVIF to JPG?

Yes. The tool decodes AVIF locally and exports a standard JPG, with transparent areas filled white.

Can JPG or PNG be converted to AVIF?

Yes. Choose AVIF output and adjust quality before conversion.

Why does AVIF encoding take longer?

AVIF evaluates more advanced compression decisions than JPG or WebP, trading processing time for efficient files.

Is the AVIF sent to a server?

No. libavif runs inside this browser tab through WebAssembly.
