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.
