Convert JPG to AVIF

Convert JPG to AVIF for the smallest files supported across modern browsers. AVIF beats WebP by ~ 20% and JPG by ~ 50% at equivalent quality.

AVIF is the newest mainstream image format. It's typically 20% smaller than WebP and 50% smaller than JPG at equivalent visual quality — the strongest compression on the modern web.

The trade-off is decode cost: AVIF takes 2–3× as long to decode as JPG. For high-traffic sites the file-size win compounds; for older mobile devices the decode penalty can matter. Ship AVIF with a WebP or JPG fallback via the <picture> element.

Frequently asked questions

How do I convert JPG to AVIF?
Drop your JPG file into the tool above. It's converted to AVIF in the browser and ready to download. Multiple files can be converted at once.
Why convert JPG to AVIF?
AVIF is the newest mainstream image format. It's typically 20% smaller than WebP and 50% smaller than JPG at equivalent visual quality — the strongest compression on the modern web.
Is any quality lost when converting to AVIF?
Converting between lossy formats (like JPG to WebP) involves one round of re-encoding, so there is theoretically some quality loss — but at the default quality setting it's visually indistinguishable. Converting to a lossless format (PNG) doesn't lose data from the source.
Does the AVIF file work everywhere the JPG did?
Modern browsers, image editors, and platforms all support AVIF. Older tools (2015-era software, some third-party services) may not — if you need maximum compatibility, JPEG or PNG remain the safest fallbacks.
Are my files uploaded anywhere?
No. Conversion runs entirely in your browser using the Canvas API. Files never touch our servers, which matters for pre-publication work, client assets, or anything sensitive.
