Why convert PNG to AVIF?
PNG is the lossless king for design assets, logos and UI screenshots, but the file sizes are heavy once you ship the asset to the web. AVIF supports transparency natively and compresses much harder than PNG — a 600 KB transparent marketing PNG often comes out at 80–150 KB as AVIF, with the alpha channel intact and the visual quality preserved.
Modern browsers all render AVIF, so for site assets, PWAs and mobile apps the conversion is mostly free bandwidth. Keep the PNG copies in your design source tree — AVIF is the ship-to-the-web target. Don't convert when the recipient is Microsoft Office, an older email client, or any tool that hasn't caught up with AVIF yet.
