Find hidden text, old versions, scripts, metadata and personal data in a PDF, then make a clean copy. Everything runs locally in your browser - your files are never uploaded to a server, no registration is required, and the tool is completely free.
How to PDF Privacy Check
Choose or drop a PDF. It is scanned in your browser and never uploaded.
Read the summary, then open each section to see what was found and why it matters.
Use 'Redact selected in Redact PDF' to remove personal data or text hidden under boxes for real.
Pick the options you want and press 'Create clean copy', then check the before/after table and download.
Features
Fake redaction detector: Finds text that is only covered by a black box and can still be selected or copied, and shows you the leaked words.
Earlier versions: Detects incremental saves, shows text from the first version that is gone from the current one, and lets you download that first version.
Scripts and actions: Counts JavaScript, open actions, Launch and form-submit actions wherever they sit in the file.
Personal data scan: Finds emails, phone numbers, card numbers (Luhn-checked), IBANs (mod-97), US SSNs, Aadhaar (Verhoeff) and PAN numbers, and dates of birth, shown masked.
Clean copy with proof: Rebuilds the PDF from its pages only, strips metadata, history, attachments and scripts, then scans the result again so you can see what changed.
Nothing uploaded: All checks run on your device. The engines load from pinned, integrity-checked URLs.
Frequently asked questions
Is my PDF uploaded?
No. The scan and the clean copy both run in your browser, and the file never leaves your device.
What is a fake redaction?
A black rectangle drawn over text. The page looks redacted, but the text is still in the file, so anyone can select, copy or search it. The check only flags text a reader can actually extract.
Does the clean copy remove text hidden under black boxes?
No. The clean copy keeps page content as it is. To really remove text, use Redact PDF, which rewrites the affected pages as images. The 'Redact' buttons open it with the file and the values already filled in.
Can it read scanned documents?
Only the text layer is checked. Text that exists only inside an image (a scan without OCR) cannot be checked for personal data or hidden text.
Will a signed PDF stay signed?
No. Rebuilding the file removes its digital signature, and the tool warns you about this before you make a clean copy.
