About the WebP to AVIF Converter
Convert WebP to AVIF online for free, with no account and no watermark. Many older apps, photo editors and upload forms still reject WebP files, so switching to AVIF is the quickest way to get the smallest next-generation web images for the smallest possible website images and Core Web Vitals optimisation.
The converter decodes your WebP with your browser's own image engine and writes the AVIF with a small open-source AVIF encoder, so quality settings are applied precisely. Because everything happens on your own device, your images are never uploaded, stored or seen by anyone else, which makes it safe for ID photos, Aadhaar or PAN scans and personal pictures.
What to expect: transparency is preserved because both WebP and AVIF support an alpha channel; only the first frame of an animated WebP is converted; AVIF is compressed, and the quality slider lets you trade file size against detail; camera metadata such as GPS location is removed because the image is re-encoded.
How to use the WebP to AVIF Converter
- Click "Choose files" or drag your WebP images onto the box. You can add several at once.
- Adjust the AVIF quality slider (85 is a good default) and, if you like, set a maximum width to resize.
- Press "Convert to AVIF". The conversion runs on your device and shows its progress.
- Download each AVIF file, or use "Download all (ZIP)" when you converted several.
- Open the result in Chrome or Edge to check it; your original WebP is never changed.
Tips & benchmarks
- AVIF encoding is slower than JPG; a quality of 50–65 already looks excellent and gives tiny files.
- Animated WebP files are converted from their first frame; use our video tools if you need every frame.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the AVIF to a website or government portal.
