What will I receive?
JPG to AVIF
The AVIF result is a static 8-bit image with adjustable quality and compatible transparency. Check that the receiving application supports AVIF; a smaller file is not guaranteed.

Practical guide
Re-encode a JPG photograph as AVIF for the modern web
AVIF may reduce transfer for a photograph on supported destinations, but it recompresses pixels that already came from a lossy JPG. Any improvement must be measured, and previously discarded detail cannot be recovered.
Start from an already compressed JPG
Conversion retains dimensions and creates an opaque AVIF. It adds no transparency, resolution or detail; blocks, halos and compression noise visible in JPG also become part of the new encoding.
Set quality without assuming savings
Choose a quality that protects texture, faces and gradients at publishing size. AVIF does not guarantee that every JPG becomes smaller, so compare actual size and appearance rather than applying a generic saving figure.
Compare web compatibility
Check support in the browser, CMS and distribution channel. JPG to WEBP is another modern option with a different support profile; compare both outputs from the same JPG.
Avoid false restoration
Output metadata is removed and AVIF is not a new master. Returning through AVIF to JPG adds another re-encoding step and cannot recreate the initial file, so retain JPG or its higher-quality source when available.
Frequently asked questions
Can AVIF recover quality lost in JPG?
No. Conversion re-encodes the available pixels but cannot reconstruct detail discarded by the earlier JPG compression.
Will the resulting AVIF have transparency?
No. A JPG input is opaque and the generated AVIF remains opaque; changing format cannot invent an alpha channel.
Is AVIF always smaller than JPG?
No. It depends on the content and selected quality. Compare actual size and appearance before replacing a published asset.
