Convert AVIF to JPG — right in your browser

Right-click, save image, double-click — and your photo editor shrugs. That is the usual way people meet AVIF: websites increasingly serve it because the AV1-based format is roughly half the size of JPEG at comparable quality, but plenty of desktop software, upload forms, and older tools still cannot read it. This page decodes AVIF and re-encodes it as universally compatible JPG without sending your image anywhere. The codec is compiled to WebAssembly and runs inside your browser tab, so the file you dropped is the file that stays on your disk — no server, no queue, no account.

How it works

  1. Drop .avif files below, or click to browse for them.
  2. Set JPG quality if the default of 80 isn’t what you need.
  3. Save each converted JPG as it appears.

Frequently asked questions

What is AVIF, and why do sites use it?

AVIF is an image format built on the AV1 video codec. It typically achieves around 50% smaller files than JPEG at similar visual quality, which is why performance-minded websites serve it. Browser support arrived in Chrome in 2020 and Safari in 2022, but desktop apps have lagged behind.

Will converting to JPG reduce quality?

Both AVIF and JPG are lossy, so a second encode adds some loss. At quality 85 or above it is rarely visible. If you want a pixel-exact copy instead, use the AVIF to PNG converter — PNG is lossless.

What happens to transparency?

AVIF supports alpha transparency but JPG does not, so any transparent regions are flattened onto a white background. If you need transparency preserved, convert to PNG or WebP instead.

Is my image sent to a server for conversion?

No. Decoding and encoding both happen in your browser via WebAssembly. Open your browser’s network tab while converting if you want proof — you will see no upload requests.
