AVIF delivers the best compression of any current image format, which is precisely why performance-minded websites serve it — and precisely why the file you just saved will not open in most desktop applications. Converting to JPG trades that efficiency for universal compatibility: the resulting file will be larger, but it will open on every device you own.

Before you convert: JPG cannot store transparency. Any transparent area in your AVIF file will be filled with a solid background colour — white by default. If you need the transparency preserved, convert to PNG or WebP instead.

Before you convert: JPG does not support animation. If your AVIF file is animated, only the first frame is converted.

Before you convert: Both formats are lossy, so the image is re-encoded once. The quality loss is minor at default settings, but avoid repeatedly converting the same file back and forth.

How to convert AVIF to JPG

  1. Select your AVIF files. Click "Choose AVIF files" or drag them onto the box above. You can select as many as you like at once.
  2. Wait for the conversion. Each file is converted to JPG on your own device. Nothing is uploaded, so it finishes as fast as your hardware allows.
  3. Download the results. Download files individually, or take them all at once as a single ZIP archive.

About AVIF files

AVIF applies the AV1 video codec to still images and currently achieves the best compression of any widely-deployed format, often half the size of a JPG at comparable quality. It also handles transparency, animation, HDR, and wide colour gamut. The catch is reach: browser support is good, but support outside the browser is thin, which is exactly why people convert AVIF files back to JPG or PNG.

Where they come from: Images saved from modern, performance-focused websites.

Drawbacks of AVIF

  • Very limited support in desktop and mobile applications
  • Slow to encode compared with JPG or WebP

Why convert to JPG?

JPG (also written JPEG) has been the default photographic format since 1992 and remains the most universally supported image format in existence. It uses lossy compression tuned for photographs, discarding detail the human eye is least likely to notice. Every operating system, browser, printer, and photo kiosk on the market reads it without complaint.

  • Opens on literally any device or application
  • Small files for photographic content
  • Adjustable quality-to-size tradeoff

Support: Universal. Supported in every browser ever shipped.

Common questions

Are my files uploaded to a server?

No. The conversion runs entirely inside your browser using your own device’s processor. Your AVIF file is never transmitted, never stored, and never seen by us — you can disconnect from the internet after the page loads and it will still work.

Is there a file size or daily limit?

There is no daily limit and no account required. Because your device does the work rather than our server, we have no per-conversion cost to recover. The practical ceiling is your device's available memory — very large files on older phones may fail, in which case convert them in smaller batches.

Can I convert several AVIF files at once?

Yes. Select or drop as many AVIF files as you like and they are converted one after another, then offered as individual downloads or a single ZIP.

Will I lose the transparent background?

Yes — JPG has no way to store transparency, so transparent pixels are filled with a solid colour. Convert to PNG or WebP if the transparent background matters.

Will the quality drop?

JPG is a lossy format, so some data is discarded. We default to a high quality setting where the difference is not visible on normal viewing, and you can raise or lower it before converting.

Why can I not open AVIF files in my photo editor?

AVIF is a web-first format. Browsers all support it, but a great deal of desktop software — including older versions of Photoshop and most default photo viewers — has never added support. JPG is understood everywhere.
