FAQ – PDF Redaction
What is permanent PDF redaction and how is it different from simply covering text?
Permanent redaction removes the underlying data, while covering or highlighting only hides it visually and can still be uncovered.
Can I redact sensitive information from a scanned PDF file?
Yes, but scanned PDFs require OCR (optical character recognition) to detect text before you can securely redact it.
How secure is online PDF redaction and are my files stored on the server?
A reliable service such as FILPDF uses encrypted connections and automatically deletes files after processing to keep your data private.
Is it possible to recover or undo redacted content after saving the PDF?
No, once a redaction is applied and the file is saved, the hidden information is permanently removed and cannot be restored.
Can I redact multiple instances of the same word or phrase at once?
Yes, advanced tools like FILPDF Redact PDF let you search for keywords such as names, emails, or phone numbers and remove all matches in one step.
Does PDF redaction also remove hidden metadata or comments inside the document?
Good redaction tools include options to clean metadata, annotations, and hidden layers to prevent accidental disclosure.
Which devices or operating systems support online PDF redaction?
You can redact PDFs directly in your browser on Windows, Mac, Android, and iOS without installing any software.
Is online redaction suitable for legal, medical, or financial documents?
Yes, as long as the service provides permanent deletion of data and complies with privacy standards such as GDPR or HIPAA.
