JPG to AVIF: what changes?
The AVIF result
The AVIF encoder writes an 8-bit still image at quality 50. It uses a separate single-threaded WebAssembly module in a background worker.
Keep your JPG until you have compared the AVIF appearance and checked acceptance in the destination app.
A PRACTICAL GUIDE
