How to use it
- Drop your AVIF images here.
- Set the JPG quality (90% by default).
- Click Convert.
- Download the JPG, or a ZIP for several files.
What is AVIF?
AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec, developed by the Alliance for Open Media. It compresses photos even more efficiently than WebP, so a growing number of websites, CDNs and image services deliver AVIF to browsers that support it.
That is why you may end up with an .avif file when you save an image from a website. Current versions of Chrome, Edge, Firefox and Safari can display AVIF, but plenty of other software cannot yet: older photo viewers and editors, office programs, many upload forms and print services.
How the conversion works
The tool uses your browser's own AVIF decoder to read each image, then saves it as a standard JPG. Nothing is uploaded, and your images stay on your device.
- Batch support: convert many files at once; they download as one ZIP.
- Quality slider: 90% is visually identical to the source; 75–85% makes smaller files for email.
- Transparency: JPG has no transparency, so transparent areas become white. Use AVIF to PNG to keep them.
- Animated AVIF: only the first frame is converted.
If the converter reports that the file cannot be opened, your browser probably lacks AVIF support. Update it, or try a current version of Chrome, Edge, Firefox or Safari.
AVIF vs. WebP vs. JPG
| AVIF | WebP | JPG | |
|---|---|---|---|
| Compression | Best | Very good | Good |
| Transparency | Yes | Yes | No |
| HDR and wide color | Yes | No | No |
| Browser support | Current browsers | Current browsers | Universal |
| Support in other apps | Growing | Good | Universal |
| Best for | Modern websites | Websites | Sharing, printing, uploads |
For your own website, AVIF and WebP are both excellent. For anything leaving the browser, such as email, documents and prints, JPG remains the safest choice because every device and program can open it.
After converting
A converted JPG is usually larger than the AVIF original, sometimes much larger. That is expected: JPG is a less efficient format. If the file must stay small, try these:
- Lower the quality slider to 75–80% before converting.
- Use Compress image with a target size in KB.
- Shrink the dimensions with Resize image if the image is larger than you need.
Remember that changing the format does not change the copyright of an image you saved from the web.
Colors may look slightly different. Some AVIF images use wide color or HDR. JPG stores standard color, so very saturated or bright HDR areas are mapped to the closest standard colors. On most images you will not notice any change.
Other converters
Converting a batch is just as easy as a single file: drop them all, and each image is decoded and saved in turn before the ZIP downloads.
Need a different output? AVIF to PNG keeps transparency and is lossless. The image converter takes AVIF, HEIC, WebP, TIFF and more and saves JPG, PNG, WebP, ICO or GIF.
Frequently asked questions
How do I open an AVIF file?
Drag it into a current browser such as Chrome, Edge, Firefox or Safari to view it. To use it elsewhere, convert it to JPG here.
How do I convert AVIF to JPG?
Drop the AVIF files on this page and click Convert. The JPGs download straight away.
Why does the converter say it cannot open my AVIF?
The tool relies on your browser's AVIF support. Update your browser or use a current version of Chrome, Edge, Firefox or Safari.
Is anything uploaded?
No. AVIF decoding and JPG encoding both happen in your browser.
Why is the JPG bigger than the AVIF?
AVIF compresses much more efficiently than JPG, so the same image needs more bytes as JPG.
