Questions

How is this different from Compress?

Compress re-encodes images and trades quality for size. Optimize is lossless: it removes waste and reorders the file for streaming.

What is linearisation?

It puts the first page at the front of the file so a reader can display it while the rest is still loading.

Security note

Files are checked to be what they claim (by content, not extension), processed in a sandboxed worker with no network, and deleted on the schedule your plan sets. We do not run antivirus and do not claim to — please do not upload files you do not trust. Read the security page.
