AVIF files tend to show up on your machine uninvited. Right-click and save an image from a modern website and there is a good chance you get a .avif file instead of the .jpg you expected, because many sites now serve AVIF to browsers that can display it. The format is excellent for the web — often half the size of a JPEG at the same visual quality — but the moment you try to attach that file to an email, drop it into an upload form, or open it in older software, things start failing. JPEG is still the format the rest of the world runs on.
This converter turns AVIF into standard JPEG directly in your browser. The page loads a WebAssembly decoder, reads the AV1-compressed image data on your device, and re-encodes it as a JPEG you can use anywhere. A quality slider, set to 85 by default, gives a sensible balance between file size and visible detail for most photos. Push it toward 95 when the image matters and size does not; pull it down when you need something small enough for a strict upload limit.
A few things are worth knowing before you convert. JPEG cannot store transparency, so any transparent areas in your AVIF get flattened onto a solid background — pick PNG or WebP instead if you need the alpha channel to survive. JPEG is also an 8-bit format, which means a 10-bit HDR AVIF loses its extended range on the way through. Expect the JPEG to come out larger than the AVIF it came from, too; that is not a bug, just AVIF being the more efficient codec. And because AV1 is computationally heavy, very large AVIF files can take a few seconds to process.
Everything happens locally. Your image is never uploaded, there is no account to create, and there are no watermarks or file limits to work around. Because everything runs on your own hardware, conversion speed depends on your machine rather than on a server somewhere else.
Why convert AVIF to JPEG?
- JPEG opens on effectively every device, app, and operating system made in the last twenty-five years
- Upload forms, email clients, and messaging apps that reject .avif files accept JPEG without complaint
- Print services and photo labs almost universally expect JPEG submissions
- Older image editors and photo viewers cannot decode AVIF at all
How it works
- Step 1
Drop your files
Drag your AVIF files into the converter above, or click “Choose files”. Batches are welcome.
- Step 2
Pick your settings
JPEG is preselected. Adjust quality or size if you want, or keep the defaults.
- Step 3
Convert and download
Conversion runs locally in your browser. Download files individually or grab everything as a zip.
Frequently asked questions
- Is my AVIF file uploaded anywhere during conversion?
- No. The decoding and encoding both run inside your browser using WebAssembly. The file never leaves your device — the only download involved is the conversion engine itself, which your browser fetches once (about 5 MB) and caches for next time.
- What happens to transparency when I convert AVIF to JPEG?
- It is lost. JPEG has no alpha channel, so transparent regions are flattened onto a solid background during conversion. If the transparency matters — a logo, a cutout, a UI asset — convert to PNG or WebP instead, since both keep the alpha channel intact.
- How much quality will I lose?
- Both AVIF and JPEG are lossy, so re-encoding adds a small amount of generational loss on top of whatever the AVIF already had. At the default quality of 85 the difference is rarely visible in normal photos. If you plan to edit the image further or print it large, raise the slider to 90-95.
- Why is the JPEG larger than the AVIF I started with?
- AVIF is simply a much more efficient format — it routinely stores the same image in half the space JPEG needs. Converting trades that efficiency for compatibility. If the output is too big, lower the quality setting; JPEG file size drops quickly below 85.
- Does the converted file keep EXIF data like location and camera info?
- You can decide. There is an option to strip EXIF metadata during conversion, which is worth using before posting a photo publicly, since EXIF can contain GPS coordinates, timestamps, and device details.
