Galleries, catalogues and digitised collections put dozens of heavy images on single pages, and there AVIF earns its keep: from clean TIFF sources it reaches sizes other formats cannot, cutting page weight where it hurts most. Lossless TIFF input gives the encoder ideal material. The costs stay the usual pair, slow encoding and no support in older software, both usually irrelevant to web publishing. Encoding runs in your browser, one file at a time or batched on Pro.

An 85 MB scan resized for display and encoded as AVIF lands under 1 MB; a gallery of forty becomes servable.

Questions

AVIF or WebP for a gallery?

AVIF for the smallest transfer, WebP for faster conversion and marginally wider support; many sites serve both and let browsers choose.

Do fine art details survive?

At the default quality, remarkably well. For critical detail, raise quality or offer a zoom tier from the lossless master.

Where does the encoding run?

Locally in the browser; collections never leave your machine.
