Redact a PDF, Permanently
Drawing a black rectangle over a PDF doesn’t hide anything: the text underneath can still be copied or searched. SignPDF’s redaction deletes the text under the area from the file and erases any image pixels beneath it, then draws a solid box. What you redact is really gone.

Why SignPDF
Built for documents that matter
True removal
Text under the box is deleted from the page content and can’t be copied, searched or recovered.
Images too
Pixels of photos or scans under the area are blanked, not just covered.
Character-precise
Only the characters inside the box are removed; the rest of the line stays intact.
Private by design
Redaction happens in your browser. The unredacted document is never uploaded anywhere.
Good to know
- Redaction can’t be undone once you download the file, so keep your original.
- Use Find & replace to locate every mention of a name or number before redacting it.
