Questions

What dpi should I choose?

150 dpi is fine on screen; 300 dpi is the usual floor for printing. Most phone-camera scans arrive far above either.

Is this reversible?

No. Discarded pixels are gone, so keep the original if you may need it later.

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.
