Built for patient privacy
PHI stays on-device
Records are processed locally, so protected health information is never transmitted to a third party.
Permanent removal
Names, DOBs and MRNs inside a marked area are deleted from the file, not just hidden.
Auto-detect identifiers
Scan for emails, phone and ID numbers to catch identifiers you might miss.
Why not to upload medical records
Sharing a case for teaching, research or a second opinion usually means stripping protected health information first. Uploading the record to an online tool to do that hands a copy of the PHI to a third party — exactly what privacy rules are designed to prevent. pdfnoupload performs the redaction in your browser, so the record never reaches an outside server in the first place.
De-identify with confidence
A black rectangle on top of a name is not de-identification if the text is still in the file. This tool removes the underlying content inside each marked region using MuPDF, then draws the bar. Combined with automatic detection of common identifiers, it helps you produce a genuinely de-identified PDF without sending anything anywhere.
Frequently asked questions
Does my patient file get uploaded?+
No. All redaction happens in your browser; verify zero uploads in DevTools → Network.
Is this tool itself HIPAA-compliant?+
Compliance is about your overall process, but this tool helps by never transmitting the file — the PHI stays on your device throughout.
Is the data actually removed?+
Yes. The text and image content inside each redaction is deleted from the PDF, not covered.
Can it catch identifiers automatically?+
It can scan for emails, phone numbers and ID-style numbers and mark them, as a safety net alongside your manual review.
