Hero images and artwork panels take the biggest bites of page weight, and shipping them as AVIF minimises it. Converting straight from the PSD skips the export-then-optimise chain: the flattened composite feeds the encoder directly, transparency included, at the strongest compression browsers accept. Encoding is unhurried, particularly on large canvases, and runs locally. Old-software compatibility remains AVIF's trade, irrelevant when the target is a modern site with fallbacks.

IdenticalNoticeably degradedWhat most listeners or viewers notice
From clean composite source at default quality, AVIF output sits close to indistinguishable; only aggressive size targets move it visibly right.

Questions

Why convert from the PSD rather than an exported PNG?

Fewer steps and identical input quality: the composite is what the PNG would have contained anyway. The chain shortens, the result matches.

How slow is slow, for encoding?

Large canvases can take a minute. It happens once, on your machine, and buys the smallest deliverable.

What about 16-bit master files?

Refused with a message; export an 8-bit RGB copy from the design tool first.
