WebP to AVIF
Convert WebP to next-gen AVIF for the smallest high-quality files. Runs in your browser.
Convert WebP to AVIF entirely in your browser. The file is decoded and re-encoded on your own device using the browser's built-in image engine, so it is never uploaded to a server — useful for private screenshots, ID scans, or client work you would rather not send anywhere. There is no signup, no watermark, and no file-size limit beyond your device's memory.
WebP is a modern web format, roughly 25–35% smaller than JPG/PNG at the same quality. AVIF is a next-generation format with the best compression, supported by modern browsers.

WebP vs AVIF: what changes
WebP: WebP is a modern web format, roughly 25–35% smaller than JPG/PNG at the same quality.
AVIF: AVIF is a next-generation format with the best compression, supported by modern browsers.
AVIF uses modern compression that beats JPG, PNG, and WebP at the same visual quality, so pick a quality around 80 for a file that looks identical at a fraction of the size. Export needs a recent Chrome or Edge.
Why convert in your browser
Most online converters upload your image to a remote server, process it there, and send it back — which means your file sits on someone else's machine. This tool runs the whole conversion locally in your browser tab, so the image never leaves your device. There is no upload wait, no per-file size cap, and sensitive images stay private. Once the page has loaded, it even works offline.
Quick tips
- ✓Keep your original WebP. Converting does not delete it, and you may want to re-export at a different quality later.
- ✓For photos, quality around 80 is the sweet spot: visually identical to the original at a much smaller size.
- ✓AVIF is a good fit when you want the smallest possible file and your destination supports modern formats.
- ✓Converting does not change the pixel dimensions — only the format and file size. Use a resize tool first if you also need the image smaller.
- ✓Browser-based conversion usually strips EXIF metadata like GPS and camera info, which is often a privacy plus when sharing photos.
