Frequently Asked Questions
Is redacted text permanently removed or just hidden under a box?
Our redactor flattens vector layers into canvas bitmaps, ensuring underlying text cannot be selected or copied by PDF readers.
Can someone undo redaction after downloading the file?
No, once flattened, redaction is permanent and irreversible.
Why redact documents before public sharing?
Redaction prevents identity theft, leaks of private financial data, and breaches of confidentiality agreements.
