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.
