Lower values = smaller file, more compression. 85 is a good default.

About the JPG to AVIF

AVIF is the most efficient mainstream image format, often producing files half the size of an equivalent JPEG at the same quality. Converting JPG to AVIF is a fast way to slim down web images and speed up your pages. Handytool encodes AVIF entirely in your browser, so your photos are never uploaded to a server.

JPG to AVIF features

  • 01

    Dramatically smaller files

    AVIF's AV1-based compression frequently beats JPEG by 40–50% at the same visual quality, making it excellent for image-heavy pages and mobile.

  • 02

    Quality slider

    Since JPG is already lossy, the slider controls the AVIF re-encode. A high setting keeps the photo looking identical while still cutting size.

  • 03

    100% private, no upload

    AVIF encoding runs locally in your browser. Your images never touch a server, so it's safe for personal photos.

JPG to AVIF FAQ

How do I convert JPG to AVIF?
Drop your .jpg or .jpeg files onto the upload area (or click Choose files), set the quality slider, then click Convert. Download the AVIF files individually or all at once.
How much smaller is AVIF than JPG?
AVIF typically produces files 40–50% smaller than JPEG at comparable quality. The exact savings depend on the image, but detailed photos benefit the most.
Do all browsers support AVIF?
Support is broad but not universal: Chrome, Firefox, Edge, Opera, and Safari 16+ display AVIF. A small share of older browsers can't, so keep a JPG fallback for critical images.
Will image quality suffer?
Your JPG is already lossy, so AVIF adds a second encode. At high quality the result is visually identical; only push the quality down when maximum size savings matter more than pixel-perfect fidelity.
Can I convert several JPGs to AVIF at once?
Yes. Add as many JPG files as you like and they are all encoded to AVIF in one batch.
