Image to AVIF - Free Online | FunToolX

Select AVIF as the target format after uploading pictures, and you can adjust the compression quality (1-100) and encoding speed. Quality 60-75 usually achieves the best balance between image quality and volume. The page displays the file size comparison before and after compression in real time. AVIF is usually more than 50% smaller than JPEG.

AVIF is based on the AV1 video coding standard and is currently one of the picture formats with the highest compression rates. The encoding process is done locally in the browser via the WebAssembly version of libavif, without uploading files. It should be noted that AVIF encoding is slow and large pictures may take a few seconds to wait.

Suitable for websites to optimize image loading speed and reduce CDN traffic costs. It is also suitable for photographers to archive high-quality photos with AVIF. Pay attention to whether the target platform supports the AVIF format.

The online picture to AVIF tool converts PNG, JPEG, WebP and other formats to AVIF format, greatly compresses the file size, and processes it locally by the browser.
