AVIF to JPG Converter

AV1 Image File Format (AVIF) is a lossy image format used for highly compressed modern images and complex photos. Files saved as AVIF usually come from AOMedia. Before converting, check that the source is the highest-quality copy you have, because every later step can only preserve what is already there.

The target is JPEG Interchange Format (JPG), a lossy image format chosen for photos. Both stages are lossy, so re-encoding adds one more generation of compression artifacts; start from the best source and avoid repeating the step. The output keeps the original dimensions or sample rate unless you change them, so this step changes the encoding rather than the content.

JPEG output is baseline DCT with a quality setting, and any transparency is composited onto white. It is the safest format for upload forms and email. The source can carry an alpha channel but {toExt} cannot, so transparency is flattened onto a solid background during encoding. File size stays close to the source because both sides use comparable encoding efficiency.

This conversion runs locally in your browser tab through Canvas or FFmpeg.wasm. The file is read from your device, decoded, re-encoded and handed back as a download; it is not uploaded to a conversion server. That keeps private recordings, client material and unreleased artwork off shared infrastructure.

After the download, play or open the result before deleting the original. Check the first and last seconds, confirm that transparency, rotation metadata or sample rate survived, and compare file sizes. If something looks wrong, retry with a higher quality setting rather than converting the output again.
