WebP has slightly broader support than AVIF across older devices and tools, while still being much smaller than JPG or PNG. Converting AVIF to WebP is handy when a platform accepts WebP but not yet AVIF.
As always, conversion happens locally in your browser — your files stay on your device.
How to convert AVIF to WebP
- Drop your .avif files above.
- Set the quality level.
- Download your WebP files (or a ZIP).
AVIF vs WebP
Both are modern, efficient web formats that beat JPG and PNG on size. AVIF generally compresses a little better, while WebP has been around longer and is accepted by a few more tools and platforms. If a service rejects AVIF, WebP is usually the next best step down before falling back to JPG.
When WebP is the better choice
There are good reasons to pick WebP over the newer format:
A CMS, marketplace, or upload form accepts WebP but not AVIF yet.
You want slightly wider support across older apps and devices.
You need strong compression and animation support in one format.
Transparency and quality
WebP supports an alpha channel, so any transparency in your original is preserved with no flattening or added background. Use the quality slider to balance file size against detail — around 75–85 looks great for most photos, while flat graphics and logos can go lower and still look perfect.

Frequently asked questions
Is WebP better supported than AVIF?
WebP has been supported slightly longer and is accepted by a few more older tools, though all current browsers support both.
Does it keep transparency?
Yes, WebP supports an alpha channel, so transparency is preserved.
Will the WebP be larger than the AVIF?
Sometimes slightly, since AVIF compresses a touch better — but you gain broader support, and both are far smaller than JPG or PNG.
Does converting lose quality?
WebP is lossy by default, but at sensible quality the difference is invisible. Raise the slider for near-lossless results.
Are my files uploaded?
No — conversion runs in your browser.
Can I batch convert?
Yes, and download everything as a ZIP.
