Questions

Will this make my file smaller?

Usually a lot. A clean white background compresses far better than a mottled grey one.

Could it remove faint content?

Aggressive settings can drop light pencil marks. Preview before applying, and keep the original.

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.
