AVIF to WebP Converter - Convert AVIF to WebP Online Free

Upload your AVIF images by dragging them onto the upload area or clicking to browse, choose your WebP quality, then download the converted WebP files individually or as a ZIP. The whole process happens instantly in your browser.

Set the quality slider to 85-95% before converting. At that level WebP keeps fine detail, gradients, and edges sharp, so the result looks identical to the original. For the best possible result, always convert from the original AVIF rather than a re-saved copy.

Yes. Select or drag in as many AVIF files as you like and they all convert together with no file-count limit. Download them one at a time, or grab the whole batch in a single ZIP archive.

Usually AVIF is the smaller format, so a WebP may be slightly larger at the same quality. You gain much wider compatibility in return. You can lower the quality slider to reduce the WebP file size, and each result shows the exact size so you can compare before downloading.

The converter decodes AVIF using your browser. Almost all current browsers support AVIF (Chrome, Firefox, Edge, and Safari 16+), but a very old browser may not. If a file fails, update your browser or try it in Chrome or Firefox.

Open this page in Chrome, Edge, or Firefox, drag your .avif files onto the upload box, and download the WebP files. There is nothing to install and no extra codecs are required.

In Safari 16+ or Chrome on macOS, drop your AVIF images onto the upload area and save the WebP results. It is faster than exporting each file from Preview one by one.

Open the page in your mobile browser, tap the upload area, and choose AVIF images from Files, Photos, or Downloads. After converting, use the download or share option to save each WebP back to your device.

Many websites now serve images in AVIF so pages load faster, so saving a picture often gives you a .avif file that some apps will not open. Converting it to WebP here produces a modern, widely supported image.

AVIF is a newer format based on the AV1 codec that compresses about 20-30% smaller than WebP and supports HDR, but it is supported in fewer places. WebP is slightly larger but has been supported across browsers and tools for years, so converting to WebP improves compatibility.

Convert the AVIF to WebP here, then upload the WebP to your WordPress media library. WordPress has supported WebP since version 5.8, so it displays the image and generates thumbnails normally - no plugin, code, or server change needed. Quality of 82-88% keeps images sharp while loading fast.

Open the file picker and select every AVIF (Ctrl+A on Windows or Cmd+A on Mac), or drag the whole selection onto the upload box. They all convert at once with no file-count limit, each keeping its original name with a .webp extension, and you can grab the entire batch with Download All (ZIP).

Drag the .avif file you saved in Chrome straight onto this converter and download it as WebP. You don't need to change any Chrome flags, install codecs, or re-save through another app. The same steps work for downloads from Edge, Firefox, and Brave.

Shopify doesn't accept AVIF uploads but fully supports WebP, so convert your product shots to WebP here at 85-90% quality. Detail stays crisp, pages load fast, and transparency on cut-out product images is preserved so items sit cleanly on your theme background.

Both AVIF and WebP support a true alpha channel, so a transparent AVIF logo stays transparent as WebP with no white box or matte edge. Upload the logo, keep quality at 90% or higher to protect crisp lettering, and download the WebP.

Open this page in Safari or Chrome on your iPhone, tap the upload area, and choose your AVIF files from Photos or Files. The conversion runs on-device and the share or download sheet saves each WebP back to your phone - no App Store install and nothing uploaded.

Convert your AVIF to WebP here, then attach the result in Discord or WhatsApp. WebP previews reliably and its smaller size uploads faster on mobile data, and transparency is preserved, which is useful for stickers and cut-out memes.

Converting AVIF to WebP gives you an attachment that opens in current versions of Gmail, Outlook, and Apple Mail. For the widest possible reach, including older mail clients, convert to JPG instead using our Image Format Converter.

WebP is typically 25-35% smaller than JPG or PNG, so serving WebP keeps Core Web Vitals healthy while staying compatible with browsers that can't decode AVIF. Lower the quality slider to trim size further, compare the before and after bytes on each result, and compress more with our Image Compressor.

Yes. Every WebP exported here has no watermark, no logo, and no size cap, and is free to use for client work, products, and commercial projects. There's no signup or daily limit, and because files never leave your device it's safe for confidential brand assets.
