AVIF (AV1 Image File Format) is the newest major image format, derived from the royalty-free AV1 video codec developed by the Alliance for Open Media. Its compression capabilities are remarkable: AVIF files are typically up to 50% smaller than JPEG and 20% smaller than WebP at equivalent perceptual quality. This makes it the most space-efficient format available for photographic and graphic content on the web today.

Our converter transforms any image — JPG, PNG, WebP, HEIC, HEIF, BMP, or TIFF — into optimized AVIF directly in your browser. No server upload, no file size limits, completely private processing on your own device.

As of 2026, AVIF is supported by approximately 93% of browsers globally, including Chrome, Firefox, Safari 16+, Edge, and Opera. For the remaining browsers, you can use the HTML <picture> element with a WebP or JPEG fallback. Major platforms like Netflix, YouTube, and Shopify have already adopted AVIF to reduce bandwidth costs. If your site serves millions of images, switching to AVIF can save terabytes of data transfer monthly.
