Convert AVIF to JPG
Free, private and fast: everything runs in your browser and your AVIF files are never uploaded.
AVIF to JPG: why convert
AVIF is one of the newest image formats on the web. It packs a picture compressed with the AV1 video codec into a HEIF file, and image services and large websites increasingly deliver it because the files are small. When you save such a picture you get a .avif file, and many programs cannot open it yet: older photo viewers, plenty of editors and office programs, messaging apps and upload forms. Converting to JPG gives you a file that works everywhere. Drop your AVIF images here, choose the JPG quality and download the JPGs. Your browser's own AVIF decoder reads the files, which current Chrome, Edge, Firefox and Safari have, so nothing is uploaded; if the browser cannot decode a file, the page tells you which versions can.
How to convert AVIF to JPG
- Drop your .avif files in the box, or click to choose them.
- Pick a JPG quality. 90 % keeps the picture close to the original.
- Click Convert to JPG and download the JPG, or a zip with all of them.
What changes when you convert
The browser must know AVIF
The image is decoded by your browser, not by a program on a server. Chrome 85, Firefox 93, Edge 121 and Safari 16 on macOS 13 or iOS 16 and newer can read AVIF. In an older browser the file cannot be decoded and you get a message instead of a broken JPG; updating the browser or switching to another one fixes it.
HDR and 10-bit pictures
AVIF can hold 10 or 12 bits per channel and HDR brightness. A JPG holds 8 bits of standard range, so such images are converted to normal sRGB colour. Bright highlights can look flatter than on an HDR screen, and very smooth gradients can show slight banding.
Transparency becomes white
AVIF supports transparent backgrounds, JPG does not. Transparent areas are filled with white. Use a PNG converter for logos or cut-outs where the transparency matters.
Animated AVIF
AVIF files can be short animations. The JPG is a still image, so only the first frame is saved.
The JPG is larger
AV1 compression is newer and more efficient than JPG compression, so expect the JPG to be noticeably bigger than the AVIF at a similar look. Lower the quality to 80 % if the size matters.
About the formats
AVIF
AVIF (AV1 Image File Format) stores a picture compressed with AV1, the royalty-free video codec of the Alliance for Open Media, inside the same HEIF container that iPhones use for HEIC. Version 1.0 of the specification was published in 2019. Image CDNs and large websites serve AVIF because it usually gives smaller files than JPG or WebP at the same visual quality.
- Opens in current Chrome, Firefox and Safari 16 or later; Edge added it only in version 121 (2024).
- Many desktop editors, office programs, upload forms and older phones still cannot open it.
- Supports transparency, 10 and 12-bit colour, HDR and animation.
- Can be lossy or lossless, but almost every AVIF on the web is lossy.
JPG
JPG (or JPEG) is the most widely used image format for photos, supported by every camera, phone, browser and image editor. It uses lossy compression, which keeps files small at a small cost in quality.
- Best for photos; text and sharp lines can get blurry edges.
- No transparency: transparent areas become a solid colour.
- The quality setting trades file size against detail.
Frequently asked questions
Are my images uploaded?
No. The AVIF is decoded and the JPG is written by your browser, on your device.
Why can't Windows open my AVIF file?
The Photos app on Windows 10 and 11 shows AVIF only with Microsoft's AV1 Video Extension, which is free in the Microsoft Store but not installed on every PC. Many other programs have no AVIF support at all, so a JPG copy is often simpler when you send the picture to someone else.
Is AVIF better than WebP or JPG?
For file size it usually is, which is why websites use it. For compatibility JPG is still far ahead, and WebP lies in between.
The page says my AVIF could not be decoded. Why?
Either the browser is too old to read AVIF, or the file is damaged or not really an AVIF. Try the file in an up-to-date Chrome or Firefox; if it fails there too, the file itself is the problem.
