AVIF Converter
Convert an image to AVIF using your browser's own encoder where available - with a clear error if your browser can't encode AVIF.
Upload an image - this tool attempts to use your browser's own AVIF encoder, entirely locally, and tells you clearly if your browser doesn't support it.
AVIF browser encoding support is currently more limited than WebP - if conversion isn't available in your browser, the WebP Converter is a well-supported alternative.
What Is AVIF?
AVIF is a newer image format that can achieve even smaller file sizes than WebP at comparable quality in many cases, based on the AV1 video codec's compression technology.
Why Use This Tool?
For projects targeting the smallest possible file sizes on browsers that support AVIF, converting locally avoids uploading images to a third-party conversion service.
How to Use It
- Upload an image.
- Click Convert.
- If your browser supports AVIF encoding, download the result - if not, this tool reports that clearly rather than pretending to succeed.
Browser Support
Browser support for AVIF encoding (via canvas, as opposed to just viewing AVIF images) is currently more limited and inconsistent than WebP - this tool never claims universal compatibility and always checks actual support before attempting conversion.
