What AVIF is and why you might convert it
AVIF is one of the newest image formats. It is based on the AV1 video codec, developed by the Alliance for Open Media, and it often produces smaller files than both JPG and WebP at comparable quality. Many websites and CDNs now serve AVIF automatically, so saving an image from a page can leave you with an .avif file.
Support outside the browser is still catching up. Some photo editors, office suites, messaging apps and online forms cannot open AVIF at all. A JPG version works everywhere, which is the point of this converter.

How to convert AVIF to JPG
Step 1: Open a current browser
Use an up to date Chrome, Edge, Firefox or Safari 16 or later, which can all decode AVIF.
Step 2: Drop the AVIF file
Select the .avif image; it is read locally.
Step 3: Convert to JPG
The image is decoded, placed on a white background and encoded as a JPEG at quality 92.
Step 4: Download the JPG
Save it and use it in any program or upload form.
Conversion details
Native AVIF decoding
Your browser's own AVIF decoder reads the file, so no extra download is needed.
HDR and wide color
High dynamic range and wide gamut images are mapped to standard sRGB, which JPG uses.
Transparency on white
AVIF supports an alpha channel; transparent areas become white in the JPG.
Same pixel size
The JPG keeps the width and height of the AVIF.
When AVIF to JPG helps
Editing in older tools. Many editors and viewers released before 2021 cannot open AVIF.
Attaching to emails and documents. JPG is the safe choice for recipients on any device.
Upload forms. Forms that list accepted types almost always include JPG and rarely AVIF.
Printing. Print labs and kiosks expect JPG.
AVIF versus JPG in practice
AVIF is more efficient, so the JPG you get will usually be larger than the AVIF file, sometimes two or three times larger, while looking the same. That is expected: JPG compression is about thirty years older.
AVIF also supports features JPG lacks, including transparency, HDR, 10 and 12 bit color and animation. The JPG keeps the visible image only, flattened onto white, in standard 8 bit color.
If the AVIF will not open
Decoding relies on the browser. Very old browsers, and Safari versions before 16, cannot read AVIF. Updating the browser, or switching to current Chrome, Edge or Firefox, fixes that.
Animated AVIF files are converted using the first frame. Files that are damaged or only partially downloaded will fail to decode; try saving the image again from the source.
Tips for AVIF files
- If you need transparency, convert AVIF to PNG instead of JPG.
- Keep the AVIF if the image is only going on a website; it is the smaller file.
- Some sites serve AVIF only to browsers that support it; saving the same image in another browser can give you a JPG directly.
- For many AVIF files, the bulk image converter handles them in one go.
AVIF to JPG questions
What is an AVIF file?
AVIF (AV1 Image File Format) is a modern image format based on the AV1 codec. It offers strong compression, transparency, HDR and animation.
Why is the JPG larger than the AVIF?
AVIF compresses much more efficiently than JPG. The larger JPG is the trade-off for being readable almost everywhere.
Which browsers can convert AVIF here?
Current Chrome, Edge and Firefox, plus Safari 16 or later. Older browsers cannot decode AVIF.
What happens to HDR images?
They are converted to standard dynamic range sRGB, because JPG does not store HDR.
Is transparency kept?
No, JPG has no transparency; those areas become white. Choose PNG to keep it.
Is my file uploaded?
No. The conversion happens entirely on your device.
