Tools
Edit & secure
Annotate and fill PDFs, blackout private text, lock or unlock with a password, or straighten a skewed form photo.
Edit vs convert to Word
Use Edit PDF for fillable boxes, signatures, notes, and blackout. Convert to Word when you need deep rewriting, styles, or table edits across many pages.
Never hide private text with a plain markup rectangle — use Blackout so covered areas are flattened.
Passwords and scans
Protect PDF adds an open password before email. Unlock when a portal rejects encrypted uploads and you already know the password. Scan & straighten cleans skewed phone photos before you turn them into a PDF.
