AVIF to JPG Converter

AVIF is currently the most space-efficient common image format, but plenty of photo editors, older operating systems, and some upload forms still can't open it. Converting AVIF to JPG trades away some of that efficiency for compatibility that works essentially everywhere. Because AVIF and JPG both use lossy compression, this conversion re-encodes data that's already been compressed once, and it fills any transparency with a solid white background, JPG has no alpha channel. This tool converts AVIF to JPG directly in your browser, no software to install and no file uploaded to a server.

How to use

1. Upload your AVIF. Drag an AVIF file onto the drop zone or click to browse. Only AVIF files are accepted for this converter.
2. Click Convert to JPG. Adjust the quality slider first if you want, it defaults to 90%. If your AVIF has any transparent areas, they'll be filled with solid white before the image is encoded, JPG has no transparency channel to preserve them.
3. Download your JPG. Click Save to download the converted file, or Save As to pick the filename and location yourself.

AVIF vs JPG

AVIF is a newer format that typically achieves noticeably smaller file sizes than JPG at comparable visual quality, and it can support transparency, but it's not yet universally supported outside of modern browsers, many photo editors, older devices, and some content management systems still can't open it. JPG is older, less space-efficient, and has no transparency support at all, but it opens in essentially any image software made in the last three decades. Converting AVIF to JPG is a trade of efficiency for compatibility: you'll typically end up with a larger file than the AVIF source, and because both formats are lossy, this is a second round of compression on data that's already been compressed once.

Tips for best results

• This is a compatibility conversion, not an upgrade. AVIF is already smaller and often higher quality per byte than JPG. Convert to JPG only when you specifically need a file that opens in software without AVIF support, not to improve the image.
• Transparent areas become white, not removed. If your AVIF has a transparent background, the JPG version will show solid white wherever it was transparent, JPG can't represent transparency at all.
• Expect a larger file than the AVIF source. AVIF's compression is generally more efficient than JPG's, so the resulting JPG is usually bigger than the AVIF you started with, even though JPG is itself a compressed format.
• Lower the quality slider for smaller files. The default 90% keeps most photos visually close to the source. Drop it toward 50–70% if you need a smaller file and can tolerate more compression.

Why use PixMidas

• 100% private. The conversion redraws your image on a canvas and re-encodes it entirely in your browser. Your AVIF is never uploaded to any server.
• Honest about the trade-off. Converting AVIF to JPG isn't an improvement, it's a compatibility move that usually costs you file size and, if present, transparency.
• No account needed. Free and instant. Works in any modern browser, no installation required.

Frequently asked questions

Why would I convert AVIF to JPG if AVIF is already better?

Purely for compatibility. AVIF generally compresses more efficiently than JPG at the same visual quality, but plenty of photo editors, older operating systems, some email clients, and certain content platforms still can't open AVIF files at all. Converting to JPG trades away that efficiency in exchange for a format that opens virtually everywhere.

Will the JPG be larger than my AVIF file?

Usually, yes. AVIF's compression is generally more space-efficient than JPG's, so even though JPG is itself a compressed, lossy format, the resulting file is typically bigger than the AVIF you started with.

What happens to transparency in my AVIF?

It's flattened to solid white. AVIF can support a transparency channel, but JPG has no transparency support at all, so any transparent or semi-transparent pixels are filled with white before the image is encoded.

Does converting to JPG lose any quality?

Some, yes, in most cases. Both AVIF and JPG use lossy compression, so converting between them means re-encoding data that's already been compressed once. At the default 90% quality the additional loss is usually minor and hard to notice, but it isn't a pixel-perfect copy of the AVIF source.

Why can't some of my software open AVIF files?

AVIF is a relatively new format. It's well supported for viewing in current versions of Chrome, Firefox, and Safari, but many photo editors, older operating systems, some email clients, and certain content management systems haven't added support yet. Converting to JPG sidesteps that gap entirely since JPG support is essentially universal.

Is my image uploaded to a server?

No. The entire conversion runs on your device using your browser's Canvas API. Your AVIF is read locally, redrawn, and re-encoded as JPG without ever being sent anywhere.
