Free AVIF to JPG Converter
A format that is better than JPG and still gets rejected
AVIF is, on technical merit, a very good image format. It stores pictures in much less space than JPG at the same visual quality, and it handles transparency and high colour depth. And yet the first time most people meet it is when something refuses to open it. This converter turns AVIF files into JPG or PNG, singly or in a batch, in your browser, so you can use them anywhere.
What AVIF is, briefly
AVIF is built on AV1, a video compression technology designed to be efficient and free of licence fees. An AVIF image is, roughly speaking, a single frame of that kind of video, packed into an image file. That is where the small size comes from. Websites and image services are adopting it quickly because smaller images mean faster pages. The downside is that desktop software, editors, print shops and many upload forms were built before it existed.
How to convert
- Drop your AVIF files on the box, or click to choose them.
- Choose JPG or PNG in Convert to.
- Set the JPG quality. 90 percent stays very close to the original.
- If you pick JPG, choose the fill colour for transparent areas.
- Download one by one, or as a ZIP.
The tool uses your browser to read the AVIF, so it depends on the browser being able to open AVIF at all. Current versions of Chrome, Edge, Firefox and Safari can. If a file will not open, update your browser or check that the file is not damaged.
JPG, PNG or keep it as it is?
- JPG for photographs you need to open in common programs or upload to forms. The file will be larger than the AVIF.
- PNG for graphics, screenshots and images with transparency, where you want lossless output.
- Keep AVIF if you are going to use it on a website, where it is a perfectly good format, and the small size is exactly what you want.
Why does the converted file get so much bigger?
That is the cost of compatibility. AVIF is simply more efficient, so the same picture needs noticeably more space as a JPG, and even more as a PNG. A photograph that is 300 KB as AVIF might be around 600 KB as a JPG. If the larger file is a problem, convert here and then pass the result through the image compressor, or use one of the size tools such as compress image to 200KB.
What format is this file, really?
File extensions can mislead. A file named photo.jpg may actually be an AVIF or a WebP that someone renamed, and a file saved from a website may have the wrong extension altogether. If a program says a file is damaged, check its real type. Look at the file details in your system, or open it in a browser. If it displays in a browser but not in your program, it is probably one of these newer formats, and converting it here is the fix. Renaming the extension by hand does not convert anything, it only makes the label wrong.
Saving images from websites
When you right-click and save an image from a page, you get the format the site served, which is often AVIF or WebP these days, not the one the page seemed to show. That is why people so often end up with files their editors do not recognise. Converting them is quick, and once you know the cause the problem stops being mysterious.
Other formats that cause the same trouble
If your problem files end in .webp, use the WebP to JPG converter. For iPhone photos ending in .heic, use the HEIC to JPG converter. All three formats exist for the same reason: to make images smaller, and all three need converting when they meet software that does not know them. Animated AVIF files are converted as a single still frame, and converting an image does not give you the right to reuse it, so check the licence on anything you did not make.
FAQ
AVIF is an image format based on the AV1 video codec. It usually makes smaller files than JPG or WebP at the same quality.
Some apps and older software do not support AVIF yet. Converting to JPG or PNG solves that.
JPG is lossy, so a little detail can be lost. At 90 percent quality the difference is very hard to see. PNG is lossless.
AVIF compresses more efficiently than JPG, so the same picture takes more space as a JPG.
No. The conversion happens in your browser.
Yes. Choose PNG in the Convert to list for lossless output, which also keeps transparency.
