About JPG to AVIF
The JPG to AVIF converter by PdfPixels re-encodes JPG photos into the modern AVIF format, cutting file size 30–50% at the same visual quality. Upload a JPG and download the AVIF for free.
JPG to AVIF re-encodes ordinary JPG photos into AVIF, the modern format that delivers the same visual quality at a fraction of the file size — commonly 30–50% smaller. Smaller images mean faster page loads, better Core Web Vitals, cheaper data, and snappier uploads. The conversion runs server-side with a real AVIF encoder, so the output is a genuine AVIF file rather than a renamed copy.

Troubleshooting & Common Problems
My website visitors see broken images
A very old browser without AVIF support is being served AVIF directly. Use AVIF with a JPG fallback via the <picture> element instead of swapping files wholesale.
The AVIF is barely smaller than the JPG
Already well-compressed JPGs leave little room. Try a slightly lower AVIF quality, or accept that some sources compress better than others.
Frequently Asked Questions

Yes — the AVIF to JPG tool reverses the conversion at any time. Keep your original JPG if you may need it.
