Convert AVIF to JPG — Compatible Everywhere

AVIF is the most efficient image format available today, but it's not yet supported by all software and devices. If you've downloaded AVIF images that won't open in your apps, this tool converts them to universally compatible JPEG in seconds — entirely in your browser, with no upload required.

How to use this tool

  1. Upload your AVIF files

    Drag AVIF files onto the upload area or click to browse. Batch conversion of multiple files is supported.

  2. Adjust quality (optional)

    Since AVIF uses dramatically better compression than JPEG, even 90% JPG quality may produce larger files than the original. This is expected — AVIF is just more efficient. Lower quality for smaller JPEGs.

  3. Click Convert

    The browser decodes each AVIF using the AV1 codec (via WebAssembly) and re-encodes as JPEG. AVIF decoding can take a few seconds for high-resolution files.

  4. Download your JPG files

    Download immediately or grab all files as a ZIP archive. Your files are never sent to any server.

Frequently Asked Questions

What is AVIF and why isn't it widely supported yet?

AVIF (AV1 Image File Format) is based on the AV1 video codec developed by the Alliance for Open Media. It offers 40–55% better compression than JPEG and 20–30% better than WebP, while supporting HDR, wide color gamut, and transparency. Browser support is excellent (Chrome 85+, Firefox 93+, Safari 16.4+), but app and OS support is still catching up — hence the need to convert.

Why is my JPG file larger than the original AVIF?

This is completely normal. AVIF is significantly more efficient than JPEG. An image that looks great as a 100 KB AVIF might need to be 250–400 KB as JPEG at equivalent quality. If you need the smallest possible JPEG, lower the quality slider to 75–80%.

What software can open AVIF files without converting?

macOS 13 (Ventura)+, Windows 11 (with AV1 codec), all modern web browsers, GIMP 2.10.22+, Photoshop 2021+ with the AVIF plugin, and most modern Android/iOS devices support AVIF. The format is becoming mainstream but legacy software requires conversion.

Does AVIF support HDR and wide color gamut? Will that survive conversion?

AVIF supports P3 and Rec. 2020 wide color gamuts and HDR content. Our JPEG output is sRGB — HDR and wide-gamut data will be tone-mapped and color-converted to sRGB during decoding. If you need to preserve HDR, your workflow needs AVIF-native software rather than conversion to JPEG.

Is there a speed difference between AVIF and JPEG decoding?

Yes. AVIF decoding is significantly more computationally intensive than JPEG. A 2 MP AVIF might take 1–3 seconds to decode in the browser (depending on your device), while the same resolution JPEG decodes almost instantly. Progress bars show per-file status during longer conversions.
