Does PDF Redact upload my files or sensitive documents to an external server?

No. PDF Redact operates 100% client-side inside your browser via WebAssembly. Your files never leave your computer or network.

How does forensic row redaction differ from black highlight rectangles?

Standard black highlight tools merely draw an overlay rectangle over text, leaving the underlying text stream readable by search tools or copy-paste. PDF Redact forensically destroys the low-level PDF character operators and vectors, leaving zero recoverable data.

Can redacted medical records (MRN, Patient names, FIN) be recovered?

No. The redaction is permanent, irreversible, and sanitizes all document metadata and XMP streams.

PDF REDACT

Forensically irreversible row-level redaction. Permanently excises character glyphs, vector drawing streams, and bitmap pixels directly within your browser's volatile memory.

3 Redaction Scope

OPTION A Row Bounding Box

OPTION B Full Margin Band

Extends a solid black redaction bar horizontally from margin to margin across the full page width for any row containing a match.

How "Super Strong" Redaction Works

Content Stream Excision: Character drawing operators (Tj, TJ) are deleted directly from page stream arrays.
Pixel Destruction: Any bitmap image overlapping the redacted bounding box is zeroed out at the pixel level.
Zero Recovery: Text scrapers, pdftotext, screen-readers, and forensic recovery tools encounter void space.
Zero Server Footprint: Executes inside client-side WebAssembly RAM. No network transmission.

Frequently Asked Questions

Are my documents uploaded to a server?
No. All redaction happens 100% locally in your browser memory using WebAssembly. Your files are never transmitted anywhere.
Does this redact both text and scanned images?
Yes. Redaction eradicates character drawing operators from the text layer and destructively paints out overlapping bitmap image pixels.
Is document metadata sanitized?
Yes. PDF author, creator, modification dates, and XML XMP streams are scrubbed upon export.
