What AVIF is, and why it will not open

AVIF is a newer image format based on the AV1 video standard. It compresses photos very efficiently, often into smaller files than JPG or even WebP at a similar look, and it supports transparency, wide color and HDR. Websites increasingly serve AVIF to save bandwidth, and some apps and devices can save photos in it.

Support outside the browser has not caught up. Many photo viewers, image editors, office suites, upload forms, marketplaces and print services do not accept AVIF. On some Windows setups the file shows as a blank icon, or the Photos app asks for an extra extension before it will display it.

So AVIF files tend to arrive as a surprise: you save an image from a website, or someone sends you one, and it will not open where you need it. Converting it to JPG, the most widely supported image format, fixes that in one step.

How to convert AVIF to JPG, step by step

1. Open the converter in a current version of Chrome, Edge, Firefox or Safari. The browser does the decoding, so it needs to be reasonably up to date.

2. Add the AVIF file. Drop it onto the page or tap to choose it. It stays on your device. JPG, PNG, WebP and HEIC images are accepted too.

3. Set the quality. The default of 92% keeps the image looking the same. Lower values make smaller files.

4. Press Convert to JPG. The image is decoded and re-saved as a JPG in your browser, at the same width and height.

5. Download the JPG. It will open in any app, editor or form that takes images.

If you have a paid plan or credits, you can select many AVIF files at once and convert them together. Processing is unlimited. Your first few downloads need no account; after that, a free sign-in keeps them going.

AVIF vs JPG: size, quality and support

File size. AVIF is one of the most efficient image formats in common use. Expect the JPG to be larger than the AVIF it came from, sometimes noticeably so. That is not a fault in the conversion; JPG simply needs more bytes to show the same detail.

Quality. Both formats are lossy. Converting decodes the AVIF and compresses it again as JPG, so keep the quality high. At the default 92%, the JPG looks the same as the AVIF to the eye.

Support. This is where JPG wins outright. Every phone, computer, editor, email app, upload form and print service handles JPG. AVIF is displayed by current web browsers but remains patchy everywhere else.

The practical rule: keep AVIF for images that live on a website, where its small size helps pages load. Convert to JPG whenever the image has to leave the browser, to be edited, printed, uploaded or shared.

Transparency, animation and HDR

AVIF can hold more than a plain photo, and JPG cannot hold all of it.

Transparency. AVIF supports clear backgrounds; JPG does not. This converter fills transparent areas with white before saving, and blends soft edges onto white, so logos and cutouts do not end up on a black box.

Animation. Some AVIF files are short animations. A JPG is a single still image, so an animated AVIF converts as one still frame. Keep the original if you need the animation.

HDR and wide color. Some AVIF images store extra brightness or a wider range of colors than a standard screen shows. JPG is a standard-range format, so the converted image uses standard colors. Very bright highlights can look a little flatter than on an HDR display, while the image looks normal on ordinary screens and in print.

For most AVIF files, which are ordinary web photos, none of this applies, and the JPG looks the same.

Choosing the JPG quality

The quality slider controls how much the JPG compresses.

92% (default): keeps the JPG visually identical to the AVIF. Because AVIF files are usually already compressed, this is the setting to keep unless you have a reason to change it.

85–90%: a reasonable choice for images headed to a website, email or social post, where a smaller file helps.

Below 80%: only for strict upload limits. Smooth skies, skin and gradients show blocky artifacts first, and they add to any the AVIF already had.

100%: the least compression JPG allows, but still lossy, and often a much larger file for no visible gain.

If a form has a hard size limit, such as 500 KB, convert here at 92%, then use the free Image Compressor, which works toward an exact target size without you guessing the quality.

Converting AVIF Privately, Then Upscaling Small Images

Most online AVIF converters upload your file to a server, decode it there and send back a JPG. This one uses your own browser to decode the AVIF and save the JPG, all on your device. The file is never uploaded or saved on our servers.

Converting creates a fresh file from the image’s pixels, so metadata stored in the AVIF, such as camera details or location, is not carried into the JPG.

AVIF images saved from websites are often sized for a page layout rather than for print. The JPG keeps the same pixel size, so a small image stays small. Imagera’s paid AI Image Upscaler enlarges images to 4K and higher and adds detail instead of stretching pixels. It runs in the cloud and is paid with credits.

If you also have iPhone photos that will not open, the free HEIC to JPG Converter works the same way.
