Supports JPG, PNG, WebP and AVIF
This is the compromise conversion, and it is a more sensible one than it first appears. AVIF gives the smallest files; JPG gives the widest support; WebP sits between them and is often exactly where you want to be. If something in your pipeline handles WebP but not AVIF — a CMS, a plugin, an older build tool, a client's platform — converting to WebP keeps most of the efficiency benefit without falling all the way back to a format from the 1990s.
It also preserves what JPG would destroy. WebP supports an alpha channel, so a transparent AVIF stays transparent, which is not true of the AVIF-to-JPG route. For web assets like icons and logos that is decisive: converting to JPG would put them on a white rectangle, while WebP keeps them usable.
Both formats are lossy, so this is a second compression pass and you should treat it as one. AVIF discarded information when it was created, and WebP discards more, differently. The file gets larger — WebP is less efficient than AVIF, which is the price of the wider support — while the image gets slightly worse. That is an unavoidable consequence of converting between two lossy formats, and it is why starting from the original source, when you still have it, always beats converting a delivery file.
How to convert AVIF to WebP
- 1
Add the .avif file
Drop it in. Your browser decodes AVIF natively, so nothing is uploaded and the conversion runs immediately.
- 2
Choose WebP as the output
Select it from the format options. Transparency in the source is carried through without any extra setting.
- 3
Use a higher quality than usual
Because the source is already compressed, start around 85 percent rather than the 80 you might use from an original. The second pass needs headroom to stay invisible.
- 4
Compare the sizes
The WebP will be larger than the AVIF was. That difference is what you are paying for wider compatibility — check it is a trade you actually need to make.
Pro tip: Check whether you need this conversion at all before doing it. AVIF support is now broad enough in browsers that serving it directly, with a WebP or JPEG fallback for anything that cannot handle it, is usually better than converting everything down to a single lesser format. This conversion earns its place when a specific tool in your pipeline is the blocker — not as a blanket policy. If you have the original image, converting that to WebP avoids the second lossy pass entirely.
Troubleshooting: If the WebP looks softer than the AVIF, the quality setting is too low for a pre-compressed source; raise it and convert from the original .avif. If the file is larger than the AVIF, that is expected — WebP is less efficient, and the size increase is the cost of compatibility. If transparency disappeared, the output format was JPEG rather than WebP. And if your browser cannot preview the .avif at all, it lacks AVIF decoding and a current browser resolves it.
If compatibility is the goal and transparency is not needed, Convert AVIF to JPG goes further and produces smaller files. For a lossless, editable copy, Convert AVIF to PNG. To create AVIF rather than convert away from it, Convert Image to AVIF, and to reduce one in place, Compress AVIF Online. The full Convert Image tool handles any other pair.
Frequently asked questions
How do I convert AVIF to WebP?
Add the .avif file above, choose WebP as the output format, set a quality around 85 percent, and download. Transparency is preserved automatically, and the whole conversion runs in your browser with nothing uploaded.
Why convert AVIF to WebP instead of JPG?
Because WebP keeps transparency and produces smaller files than JPEG at similar quality. JPG goes further for compatibility but has no alpha channel, so a transparent AVIF would end up on a white background. WebP is the middle option that keeps most of both benefits.
Will the WebP be bigger than the AVIF?
Usually yes. AVIF compresses more efficiently, so moving to WebP means giving up some of that saving in exchange for support in tools that cannot read AVIF. Whether that trade is worth it depends entirely on what is blocking you.
Does converting between AVIF and WebP lose quality?
Yes — both are lossy, so this is a second compression pass on an already-compressed image. Using a higher quality setting than you would from an original keeps it invisible. If you still have the source image, converting that to WebP directly avoids the extra pass.
Are my files uploaded during conversion?
No. Decoding and re-encoding both happen inside your browser on your own device — nothing is uploaded, stored, or logged, and the tool works offline once loaded.
