AVIF to WebP Converter

Add your AVIF files — drag and drop or click to browse.

Set the quality — choose a quality level for the WebP output; transparency is preserved.

Convert and download — save each WebP from its card, or click Download All as ZIP. ```

Mainly for compatibility. Both are efficient, but WebP is supported in more browsers, apps, and CMS platforms today. If a tool or site rejects your AVIF, converting to WebP keeps the file small while making it work in more places.

Yes. WebP supports an alpha channel, so any transparent areas in your AVIF are preserved in the WebP. You don't need to flatten or fill the background the way you would when converting to JPG.

Often they're similar; AVIF can be marginally smaller at the same quality, but WebP is close and far smaller than PNG or JPG. The reason to convert is usually wider compatibility rather than size — you keep a small file and gain support.

WebP supports both. The quality slider controls lossy compression for the smallest files; at a high setting the result looks essentially identical to the source. For graphics that must stay pixel-perfect, keep the quality high.

This tool converts the still image (the first frame for an animated AVIF). If you specifically need an animated output, use the GIF Converter, which handles animation with frame-rate control.

AVIF is a modern, highly efficient image format based on the AV1 codec, supporting HDR, wide colour, and transparency. It's excellent for the web but not yet supported everywhere, which is why converting to WebP can help.

No. The converter runs entirely in your browser using the HTML5 Canvas, so your files are processed on your own device and never uploaded. Nothing is stored once you close the tab. That keeps your images private and makes conversion fast, because there's no upload or download to a server.

Yes. Drag in a whole batch and the tool converts them all locally. Download each result from its card, or click "Download All as ZIP" to save the entire set in one folder. There's no cap on the number of files beyond your device's memory.

Yes. It runs in your phone's browser with nothing to install, so you can convert files on Android or iOS and download the result. Small batches convert quickly; very large or high-resolution sets use more memory and are smoother on a computer, but everyday conversions work fine on mobile.

There's no artificial cap or paywall, because nothing is uploaded — the work happens on your device. The practical limit is your device's memory. A large batch of high-resolution images uses more memory and is smoother on a computer, but everyday conversions run quickly even on a phone.

No. There's nothing to download or install and no account to create. The converter runs in any modern web browser, on any operating system, so you don't need a desktop image editor or codec. Just open the page, add your files, and convert.

Yes, it's completely free with no account and no limits, and it adds no watermark — what you download is clean. Because everything runs locally in your browser, there's no paywall and no usage cap.
