Redact strings you specify

Replace the exact text you list with [REDACTED]. This is not an automatic personal data detector.

Paste the text you plan to share. Maximum 100,000 UTF-16 units; some emoji use two units.

Strings to redact

1 / 50 target

Match is case- and space-sensitive. Enter one line; line breaks and control characters are rejected. Leading and trailing spaces are kept.

Each match is replaced with [REDACTED]. Add up to 50 targets, each at most 200 UTF-16 units.

Processed copy

Paste your source, list the strings to redact, then process the text.

Only the exact strings you list are replaced. This tool does not detect other personal data. Review the full output before sharing.

How it works

Does this find all personal data?

No. It only replaces strings you list. Anything you did not list stays in the output; review the full text.

Do case and spaces matter?

Yes. Matching is case- and space-sensitive. Targets must be one line; line breaks and control characters are rejected. Leading and trailing spaces stay, with no Unicode normalization. The longest matching target at each position wins.

Is my text uploaded?

The text is processed in this browser tab and is not submitted to the tool service by design. There is no cloud storage or automatic recovery; reloading clears the text.

Clear current text?

This clears the source, all redaction targets, and the result. Cancel to keep all current data.
