Medical record numbers (MRNs) and patient IDs in shared PDFs create privacy risks for patients and compliance challenges for healthcare providers. Our free browser-based tool permanently removes MRNs and patient identifiers from PDF documents — your files never leave your browser.
- Medical record numbers can be used to access patient records, making them sensitive identifiers
- Healthcare providers sharing records for referrals or research must remove patient identifiers
- Patients requesting copies of their records may need to share them with multiple providers
- Researchers must de-identify patient data before including records in studies
