AVIF to WebP Converter — Free & Instant
AVIF is the newest image format — technically superior to WebP with even better compression — but it still has incomplete support across browsers, operating systems, and design tools. WebP, by contrast, is supported everywhere modern. Converting AVIF to WebP gives you near-identical quality at a slightly larger file size, but with essentially universal compatibility across all platforms.

Step-by-Step Guide
5 steps · takes under 1 minute
Check browser AVIF support
AVIF is supported in Chrome 85+, Firefox 93+, and Safari 16+. If your browser can display the AVIF file, the converter can process it. On older browsers, you may need to update first.
Open the Format Converter
Go to the Convert from JPG tool — it handles AVIF, WebP, PNG, and JPG as input formats in supported browsers.
Upload your AVIF file
Drag and drop the .avif file. The browser's built-in AVIF decoder reads the file for processing.
Select WebP as output
Choose WebP output. The conversion preserves colour accuracy and transparency if present in the AVIF source.
Download and verify compatibility
Download the WebP file and test it in your target environment. WebP is supported by Chrome, Firefox, Safari 14+, Edge, and all major image tools.
100% Private — Zero Uploads
ImgToolkit runs entirely in your browser using the Canvas API. Your images are never sent to a server, never stored in the cloud, and never seen by anyone else. This makes it safe for sensitive documents, client work, medical imagery, and confidential screenshots.
Pro tip
Always keep your original file before converting. Lossy formats like JPG discard data permanently — you can't restore quality that was compressed away.
