Frequently Asked Questions
Is my PDF uploaded to any remote server?
No. PDF Redact utilizes local JavaScript engines. Your files never touch an external server or cloud storage.
Can someone un-redact the blacked-out text?
No. When you export the final document, the underlying text and vectors beneath the redaction mask are permanently stripped out.
