Questions

How small an angle can it correct?

Down to a fraction of a degree, which is exactly the range that makes OCR misread lines.

Should I deskew before or after OCR?

Before. Straightening first measurably improves recognition.

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.
