How to pick

Most jobs here are one tool, but a few are two in sequence. Getting a photo under an upload limit is a resize followed by a compress, in that order — halving the width throws away three quarters of the pixels, which saves far more than any quality slider. Getting a product shot onto a clean background is a background removal followed by a resize to whatever the listing wants.

Everything runs on Zyff’s servers rather than in the page, so the result does not depend on which browser or phone you are using, and what you send is processed in memory and never stored. If you want the reasoning behind a particular setting — which format to pick, what error correction does to a QR code, why a favicon is missing from a search result — that is what the guides are for.
