JPG is the compatibility default. AVIF aims for stronger compression when browsers and platforms support it.
Ready to try the tool this guide describes?
JPG strengths
JPG opens almost everywhere: email, older apps, social uploads, and printers. It has no alpha channel.

AVIF can deliver smaller photographic files for modern sites when encoding and decoding are available.
Quality trade-offs
