How it works
Drop in your PDF
The scan runs locally — the safest place to check a sensitive file.
Review the findings
Counts by data type with page numbers and masked previews.
Decide what to do
Edit or redact the source document, then rescan to confirm it is clean.
Before a PDF leaves your desk, scan it for the things people forget are in there: email addresses, US phone numbers, SSN-pattern numbers, credit-card numbers (validated with the Luhn check), IBANs, and IPv4 addresses. Each hit shows the page number, a count per type, and a masked preview.
This is a pattern-based scan, not a legal review — it will miss data written in unusual formats and may flag harmless lookalikes. It is a fast first pass, and a genuinely private one: because the scan runs in your browser, you are not uploading the very document you are worried about to someone else’s server. To actually remove what it finds, the PDFDepth app includes real redaction.
Questions, answered
No. It is a pattern-based first pass. Unusual formats, images of text, and context-dependent data can be missed.
More free tools
Need more than the free limit?
PDFDepth adds permanent redaction — black-out sensitive text so it is removed from the file, not just hidden.
