How to redact PII
Permanently delete sensitive details — emails, card numbers, IDs — from the PDF itself, not just cover them with a black box. Bytefuse removes the underlying text, so redacted content can never be copied out or recovered.

Why Bytefuse
Everything you get with Redact PII
Fast, faithful to your document, and ready for real work — in the browser or over the API.
Truly gone
The underlying text is deleted rather than hidden, so redacted data can't be selected, copied or recovered later.

Common patterns like emails, phone numbers and card numbers are detected automatically so nothing quietly slips through.
Private by design
Files are encrypted in transit, used only for this request, and deleted within an hour of processing.
