How to permanently redact confidential PDF data

Blackout social security numbers, banking details, and private metadata so they can never be searched or recovered.

True redaction permanently removes underlying characters and metadata from the document byte stream, rather than simply drawing a cosmetic black box over the text.

1. Open Document in flarePDF

Open your document to inspect all selectable text layers and embedded vector elements.

2. Select Sensitive Information

Highlight bank account numbers, tax IDs, or private names using the Redaction tool to strip them from the file.

3. Export Sanitized Document

Save the new file with complete assurance that hidden metadata and redacted text cannot be highlighted or recovered.

Conclusion

Because processing runs purely in-browser through client-side JavaScript, sensitive legal records never travel across the internet.
