JPG to AVIF Converter

JPG to AVIF Converter encodes one JPEG locally as AVIF without uploading the source.

Purpose and limits

What this tool does

Convert one JPEG image into a compact static AVIF.

Input
One JPEG up to 25 MiB and 16.7 million decoded pixels.
Result
One lossy opaque 8-bit sRGB AVIF with metadata removed.

How to use it

  • Choose one local JPEG within the fixed limits.
  • Set the AVIF quality and review the additional-loss warning.
  • Process locally and download the resulting AVIF.

Limitations

  • AVIF encoding adds another lossy step to the already lossy JPEG source.
  • Metadata and color profiles are removed and the output is opaque 8-bit sRGB.
  • The self-hosted Worker/WASM runtime loads after explicit processing; physical mobile-device support is not claimed.
