Find sensitive information without checking every line yourself
Nerato checks your PDF for supported types of personal and sensitive data, then shows the results for review before anything is redacted.
Check for common sensitive data
Nerato looks for supported patterns and fields such as email addresses, phone numbers, IBANs, payment card numbers and identity information.
Review what Nerato finds
Detected items are highlighted in the document preview so you can decide what should be removed and what should remain.
Add anything that was missed
Automatic detection can miss sensitive information. Add manual redaction areas for anything else you do not want to share.
Privacy by design
Your PDF is temporary. Your review stays yours.
Nerato keeps the uploaded PDF only in a temporary processing session while you review detected information and create the redacted document. Temporary sessions expire automatically after 15 minutes, and completing a redaction consumes the session.

PDF PRIVACY CHECK
Check before you send, upload or publish
Sensitive information can be easy to overlook in a long document. Nerato helps surface likely personal data so you can review it before sharing.
01
Find likely personal information
Automatic detection helps locate supported sensitive-data patterns without requiring you to search the entire PDF manually.
02
Keep the final decision
Nerato does not blindly redact every detection. Review the results and choose which items should be permanently removed.
03
Check scanned pages when needed
If normal PDF text extraction is not enough, Nerato can use OCR on supported scanned or image-based pages within the service limits.
How to check a PDF for sensitive information
Upload your PDF, review the personal information Nerato detects, then redact the items that should not be shared.
1
Upload the PDF you want to check
Choose a PDF up to 20 MB. Nerato analyzes the document for supported types of sensitive information.
2
Review the detected information
Check each highlighted result. Deselect anything you want to keep and add manual redaction areas for anything that was missed.
3
Redact before sharing
Create a new PDF with the selected content permanently redacted from the generated output document.
Check a PDF for personal and sensitive information
PDFs can contain personal information that is easy to overlook before sending, uploading or publishing a document. Manually reading every line can also become impractical in longer files.
Nerato automatically checks for supported types of sensitive data and presents likely matches for review. You remain responsible for deciding what should actually be redacted.
What sensitive information can be detected?
Nerato can detect supported patterns and fields including email addresses, phone numbers, IBANs, payment card numbers, dates of birth and certain identity or document fields.
Why you should still review the PDF
Automatic detection is not guaranteed to find everything. Review the document and use manual redaction for sensitive information that was missed.
Remove selected information instead of just hiding it
When redactions are applied, Nerato removes the selected content from the generated PDF rather than simply covering it with a visual black box.
A final privacy check before sharing
Use the document preview to verify detected items and manual areas before creating the redacted copy you intend to share.
