Convert images to AVIF.
smallest modern format

When AVIF is the right output

AVIF (AV1 Image File Format) is the smallest widely deployed photo format in 2026. At similar visual quality it is often ~50% smaller than JPEG and smaller than WebP too. Use it for heroes, product galleries, and any page where bytes on the wire still matter. Chrome, Firefox, and Safari can display it.

How this converter works

Drop JPG, PNG, or WebP. The browser encodes AVIF locally. If your browser cannot encode AVIF, we fall back to WebP so you still leave with a modern, smaller file — not a failed download. Nothing is uploaded, so client work and unpublished shots never hit a server.

AVIF vs WebP vs JPEG

JPEG is the compatibility format. WebP is the safe modern default (transparency + broad encode support). AVIF is the size champion. If a CMS or CDN already serves AVIF with a JPEG fallback, convert here and keep JPEG only for the fallback. For a one-off “this must open everywhere” file, use WebP to JPG or stay on JPEG.

Quality tips

Start around 70–80% quality. AVIF holds detail well at lower settings than JPEG, which is why the files look small. If the result bands on a gradient, bump quality. If you need an exact byte cap for a form, use Compress to size — AVIF is often the easiest way to hit 50 KB without looking crushed.

Privacy

Same engine as Convert and Compress: Canvas in your tab, no account, no watermark added. That is the positioning — not “another compressor,” a toolkit that never takes the file.
