Formats involved

PowerPoint's deck format — slides ready to present or hand off.

Best for presentations and slide decks. Watch out — animations and transitions don't carry across formats.

The smallest of the lot — next-gen compression that routinely halves WebP.

Best for squeezing photos as small as they'll go for the web. Watch out — encoding is slower, and a few ancient browsers can't read it.

One pass. No site-hopping.
