Shrink your WebP images further. Convert WebP to modern AVIF right here in your browser — even smaller files, transparency preserved.
Your files never leave this device.webp · 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.
Pick an AVIF quality level — higher keeps more detail, lower makes smaller files. The default suits most images.
Latch encodes each WebP to AVIF with the AV1 codec, right in your browser — instantly and offline.
Save them one at a time, or grab everything at once in a single zip. That's it.
WebP is already a compact, modern format — but AVIF, built on the newer AV1 codec, goes further still, packing the same image into roughly 20–30% less space at the same visual quality. On large or photographic images you're shipping at scale, that extra saving helps load times and Core Web Vitals.
Both WebP and AVIF support an alpha channel, so any transparency in your WebP converts across without losing its transparent areas. AVIF also handles wide colour and high dynamic range better, making it a strong upgrade for modern web images.
The one trade-off is reach: AVIF is slightly less widely supported than WebP — very old browsers and a few legacy apps don't open it yet. If you need maximum compatibility, keep the WebP — or go the other way with AVIF to WebP.
AVIF is typically 20–30% smaller than WebP at the same visual quality, thanks to the newer AV1 codec. WebP is already efficient, so the savings are more modest than converting from PNG or JPG — but on large or photographic images they still add up.
Yes. Both WebP and AVIF support a full alpha channel, so any transparency in your WebP is preserved in the AVIF output — you get the smaller file without losing transparent areas.
This tool encodes lossy AVIF, which gives the biggest size savings. Since WebP is usually already lossy, re-encoding discards a little more detail — raise the quality slider toward the top for near-lossless results if you need an exact match.
All current browsers — Chrome, Edge, Firefox, and Safari 16 and later — display AVIF, and it's widely supported across the web. Some older apps, devices, or operating systems may not open it yet, so keep a copy of the original if you need broad compatibility.
No. Every WebP is encoded to AVIF by your own browser. Nothing is sent to a server — in fact, the tool keeps working even with your Wi-Fi switched off.
