Privacy as an instrument, not a claim.
Real redaction, not a sticker
A black box on top leaves selectable text underneath. We strip the targeted glyphs from the content stream, then paint the box on for visual confirmation.

github.com/xjmani/pdf-redactor →Custom redaction patterns
Paste an example of the text you want to redact. Words BEFORE a separator (: — - # =) stay literal (the label). Tokens AFTER a separator become variable. Dashes auto-expand to also match em-dash, en-dash, and NUL (some PDFs render dashes as NUL bytes). Edit the regex below if needed.
Saved on this device only. Auto-detect will run these alongside the built-in patterns.
