Drop AVIF files here

or — multiple files welcome. Nothing is uploaded; conversion happens on your device.

Files are processed entirely in your browser — never uploaded, never stored. Large photos convert in about a second each; the first HEIC file loads a small decoder module.

Runs fully in your browser — images are never uploaded or stored.

How it works

AVIF is the newest mainstream image format — smaller than WebP, used by big CDNs — but desktop software support still lags years behind browsers. Converting to JPG makes an AVIF file usable everywhere immediately.

  1. Drop the AVIF files above — decoding uses your browser’s built-in AVIF support (every current browser has it).
  2. Set quality; 90% preserves everything visible.
  3. Download the JPGs.

AVIF vs JPG

AVIF JPG
File size (photos) Smallest mainstream format Larger (~2×)
Encoding speed Slow Fast
Software support Browsers, few desktop apps Universal
Best for Web delivery at scale Everything else

Tip: If your source is a website image, check whether the site also serves a JPG or WebP fallback — the browser dev tools network tab often reveals one, skipping conversion entirely.

Frequently asked questions

What is an AVIF file?

AVIF is the newest mainstream image format, based on the AV1 video codec — even smaller than WebP at the same quality. Sites like Netflix and many CDNs serve it, but desktop app support lags far behind, hence the need to convert.

Why does AVIF conversion fail in my browser?

This tool relies on your browser’s native AVIF decoder. Every current Chrome, Edge, Firefox, and Safari release has one; a very old browser may not — updating fixes it.

Are my images uploaded to a server?

No. Conversion runs entirely in your browser using its built-in image engine — files never leave your device, which also makes it faster than upload-based converters and safe for private photos.
