Redact PDF
Remove confidential text and pictures from a PDF permanently, not just cover them with a black box.
What you can do
- Drag over anything to redact it; the words under it are removed from the downloaded file, not hidden.
- Before the file is made, NightOwl checks it for hidden copies of the pages.
- It also warns when a redacted word still appears in bookmarks, notes, headers or the file name.
- Find & redact finds names, phone, Aadhaar and PAN numbers everywhere (marking them all needs the trial or Professional).
How to do it
- Open Redact and choose a PDF.
- Drag over what must go, or use Find & redact.
- Download the file. Share the downloaded file: a copy saved to your account keeps the original so you can change it.
Good to know
- A redacted page is rebuilt as a picture with its remaining text kept searchable.
- It runs in your browser: the file is not uploaded to NightOwl or anyone else.
Questions
Is a black highlight the same as redaction?
No. A black box drawn over text leaves the text in the file. NightOwl removes it.
