Add up to 30 AVIF images (up to 50 MB each) and convert them to PNG, JPG or WebP. Auto, the default, encodes each image in all three and keeps the smallest, skipping JPG when the image has transparency. JPG and WebP use the quality slider (10 to 100, default 85), PNG is lossless, and the tool has its own AVIF decoder for browsers that can't read the format. Everything runs in your browser.
Convert AVIF images to PNG, JPG or WebP
AVIF (AV1 Image File Format) usually produces much smaller files than JPG at similar quality. But it's still fairly new, and many programs and older browsers can't open it. This converter turns AVIF files into formats that work almost everywhere.
Why you have AVIF files
AVIF files usually come from websites and image services that serve the smallest possible files, from image optimization tools and build pipelines, or from modern CMS platforms. Saving an image from such a site gives you an AVIF that other software may not open.
How to convert AVIF to PNG, JPG or WebP
- Add your AVIF files by dragging them in or clicking to browse.
- Choose PNG, JPG or WebP, or leave the output on Auto.
- For JPG and WebP, set the quality. PNG ignores it because it's lossless.
- Download the converted images one by one or as a ZIP.
Which output format should you choose?
PNG: lossless quality and transparency
Choose PNG when the AVIF has transparency you need, when you'll edit the image several times, when it has text, sharp edges or flat colors, or when you need an exact copy for printing, design or archiving. PNG files are much larger than AVIF, often several times larger for photos.
JPG: universal compatibility
Choose JPG for email, documents and older systems, for platforms that don't accept AVIF, and when sharing with people on older devices. JPG is lossy, has no transparency, and compresses less efficiently than AVIF, so the files are bigger. A quality of 85 to 90 works well.
WebP: a balance of size and support
Choose WebP when you want files smaller than JPG with much wider support than AVIF, or when you need transparency in a compact format. WebP files are usually somewhat larger than the AVIF but smaller than JPG, and every current browser displays them.
AVIF browser support and fallbacks
Current versions of Chrome, Firefox, Safari (16.4 and later) and Edge display AVIF, but older browsers, many email clients and many applications don't. Websites usually serve AVIF with WebP and JPG fallbacks through the <picture> element:
<picture>
<source srcset="image.avif" type="image/avif">
<source srcset="image.webp" type="image/webp">
<img src="image.jpg" alt="Description">
</picture>Browsers pick the first format they support, so modern browsers get the smallest file and everyone else still sees the image.
Quality and file size
Converting AVIF to PNG adds no new loss, but the file grows a lot, because AVIF compresses far more efficiently than PNG. Use PNG only when you need lossless quality or transparency.
AVIF to JPG adds a little lossy compression of its own, and the JPG is usually much larger than the AVIF at similar quality. Quality 85 to 90 balances size and appearance, and lower settings shrink the file but can show artifacts.
AVIF to WebP stays within modern formats. The WebP is usually somewhat larger than the AVIF, but far more software and browsers support it, which makes it a good compromise.
Frequently Asked Questions
Is AVIF better than WebP or JPG?
For compression, usually yes: AVIF files are typically much smaller than JPG and somewhat smaller than WebP at similar quality. JPG opens everywhere and WebP nearly everywhere, while AVIF needs current software. The best format depends on where the image will be used.
Will converting AVIF to JPG lose image quality?
A little, since both formats are lossy and compress differently. At quality 85 to 90 the difference is usually not visible. The JPG will be larger than the AVIF because JPG compresses less efficiently.
Can I preserve transparency when converting AVIF?
Yes, by converting to PNG or WebP, which both keep the alpha channel. JPG has no transparency, so transparent areas are filled with a solid color (white by default, or black or a custom color). Auto never picks JPG for images with transparency.
What should I do with animated AVIF files?
The converter works with still images and takes only the first frame of an animated AVIF. To keep the animation, use a dedicated tool for animated formats.
Why are my converted files larger than the original AVIF?
AVIF's AV1-based compression is more efficient than JPG, WebP and PNG, so the same image takes more bytes in those formats. That's the price of a file more systems can open.
