Protected Health Information (PHI) is any health record, clinical note, lab result, or billing artifact that can be tied back to an individual patient โ including names, dates of birth, medical record numbers (MRNs), phone numbers, email addresses, street addresses, Social Security Numbers, and more. When you digitize a chart to run research or an audit, converting it to searchable text is routine. But for a HIPAA-compliant pdf OCR free workflow, the scan must never travel to a cloud server. That is exactly what this tool is: a fully local, medical text extractor client-side tool that redacts PHI in the same browser tab where the digits happened.
The architecture is the guarantee. Tesseract.js runs compiled to WebAssembly inside your tab, so the pixels of the patient record PDF-to-text no upload conversion are decoded entirely on your machine. There is no upload handler, no API endpoint, no audit-log storage. This is not a "trust us" privacy promise โ the tool physically cannot transmit the data because no request ever carries the document. For a clinic, that removes the Business Associate Agreement (BAA) overhead entirely when processing documents internally.
How the PHI sanitizer auto-redact works
The de-identification mode runs a client-side heuristic/regex engine across the extracted text. It looks for the tell-tale shapes of medical identifiers โ a name in the top patient block, dates of birth near a DOB field, MRN patterns, SSN digit groups, phone and email formats, and street + city + ZIP address sequences โ and replaces each hit with a label like [REDACTED NAME], [REDACTED DOB], or [REDACTED MRN]. Because everything runs locally, there is no trade against accuracy, and each PHI category is a toggle you control. The result is a sanitize medical document PDF online free flow that keeps your registry private.
Medical code extraction for billing & research
The extraction mode additionally recognizes standard medical coding systems across the OCR text โ ICD-10 diagnosis codes (E11.9, I10, F41.1), CPT surgical/hit codes (99213, 93000), and RxNorm drug-based tokens โ and highlights them in the output. That lets coders, billers, and researchers pull clinical summaries to be pasted into EMRs, billing sheets, or study datasets without manually transcribing stack after stack of chart scans.
- 100% client-side: Tesseract.js WASM + PDF.js + pdf-lib, zero uploads
- HIPAA Safe Harbor-style PHI redaction with sensitivity toggles
- ICD-10, CPT & RxNorm code highlighting in extracted text
- Editable sanitized text grid; copy, CSV, JSON, or redacted PDF export
- Medical-grade privacy even against accidental sharing
Whether you are a medical biller digitizing EOBs, a researcher normalizing chart data, or a legal health consultant handling a deposition record, drop the scan into the tool above, extract, let the sanitizer statically redact identifiers, and export a clean copy โ your patient data never left your laptop, so there is nothing for an attacker to intercept and nothing for HIPAA to red-flag.
