Read-only scan — your file is never modified or uploaded. Checks document metadata (author, software used, etc.) and page text for emails, Thai phone numbers, and Thai ID numbers.
Check a PDF for two things people forget before sharing a document: hidden document metadata (author name, the software that created it, timestamps) and emails, Thai phone numbers, or Thai ID numbers sitting in the page text. Read-only — your file is never modified or uploaded.

Why Choose PurePDF for Privacy Scanner
Nothing leaves your device
The scan runs entirely in your browser — your document is never uploaded, even to check it.
Checks metadata, not just text
A PDF's Author/Producer/timestamps often leak a real name or local file path most people never think to check.
Shows exactly what matched
Each finding shows the actual matched text and page number, not just a count, so you can judge it yourself.
Common Use Cases for Privacy Scanner
Before sending a document externally
Quick check for a leftover author name or contact details before it leaves your organization.
Before publishing a report
Catch metadata or contact info that shouldn't be public before posting a document online.
Reviewing a document from someone else
See what a PDF you received actually reveals about who made it and when.
Pro Tips for Privacy Scanner
- This scan is a best-effort check, not a guarantee — always review a sensitive document yourself too.
- Found metadata you don't want? Use Edit Metadata to clear it.
- Found PII in the page text? Use Auto-Redact PII to black it out automatically, or Redact PDF to mark it by hand.
