Which browsers support AVIF?

AVIF is supported in Chrome 85+, Firefox 93+, and Safari 16+. For older browser compatibility, consider converting to WebP or JPG instead.

Does converting TIFF to AVIF lose quality?

AVIF can be lossy or lossless. The browser canvas conversion uses a standard quality setting that produces excellent visual results at a fraction of the TIFF file size.
