Turn AVIF images into widely-supported WebP files — right here in your browser. Transparency preserved.
Your files never leave this device.avif · up to 10 at once · 50 MB each
Four steps, a few seconds, zero uploads.
Drag images onto the box above, or click Browse to pick them from your device. Up to 10 at once.
Pick a WebP quality level — 80 is a great default that stays sharp while keeping files compact.
Latch decodes each AVIF and re-encodes it as a WebP using your browser — instantly and offline.
Save them one at a time, or grab everything at once in a single zip. That's it.
AVIF (AV1 Image File Format) is the most efficient image format around — often even smaller than WebP — but it's also the newest, so plenty of browsers, CMS platforms and image editors still can't open a .avif file. WebP is the pragmatic middle ground: supported almost everywhere modern, yet still far smaller than PNG or JPG.
Both AVIF and WebP support an alpha channel, so any transparency in your image carries straight across with no background colour added. Converting AVIF to WebP is about reach, not raw size — the WebP may be marginally larger than the AVIF, but it opens in far more apps, editors and older browsers.
To turn an AVIF into a WebP, drop your files above, set the quality, and hit Convert — everything runs in your browser, so the images never leave your device. Need to go the other way? WebP to AVIF squeezes them back down to the smaller AVIF format.
No. Your browser handles the entire conversion locally. Nothing is sent to a server — the tool even works with Wi-Fi switched off.

Yes. Both AVIF and WebP support an alpha channel, so any transparent areas in your AVIF carry straight through to the WebP — no background colour is added.
Often slightly, yes — AVIF compresses a little more efficiently than WebP. You convert for compatibility, not to save bytes: the WebP is still far smaller than the same image as PNG or JPG, and it opens in much more software than AVIF does. At the default quality of 80 the visual difference is negligible.
You can convert up to 10 images at once, up to 50 MB each. The real limit is your device's available memory, not an arbitrary cap we've set.
Drag your AVIF files onto the drop zone (or click Browse), set your quality, then hit Convert to WebP. Latch turns each AVIF into a WebP right in your browser and lets you download them one by one or as a single zip — convert a single file or batch several at once.
