Offline PDF Text OCR
Optical Character Recognition. 100% Local.
The Problem
Scanned medical intake forms, printed financial receipts, and physically signed legal NDAs are permanently locked inside static PDF image wrappers. Conventional Optical Character Recognition requires uploading these highly toxic, PII-dense documents to a public external API like Google Cloud Vision or AWS Textract, immediately violating complex compliance architectures.
How It Works

Choose your scanned PDF or Image file.
Render WASM
PrivacyScrubber initializes an encapsulated WebAssembly Tesseract OCR core.
Extract
Image text is converted to readable strings and instantly sanitized by the Zero-Trust engine.
How This Feature Improved Workflows
"The offline OCR is insane. We process intake forms that are literally photos of paper. It reads them locally, scrubs the SSNs, and outputs clean text for our AI systems. Highly compliant."

WebAssembly Meets Zero-Trust Visual Processing
The ultimate pinnacle of client-side security architecture is the complete elimination of the "Cloud NLP/Cloud OCR" API dependency. By bringing the immense, mathematical heavy lifting of Optical Character Recognition directly to the local endpoint, PrivacyScrubber achieves what was once considered technologically impossible: verifiable, completely offline text extraction from rasterized PDF images at enterprise deployment speeds.
We leverage a highly optimized, compiled WebAssembly (WASM) distribution of the legendary Tesseract OCR engine. This acts directly inside the secure memory sandbox of your web browser. No pixels ever leave your device, meaning you can finally bring massive stacks of scanned sensitive paperwork into the Generative AI era without compromising a single layer of patient, client, or personal confidentiality.
Frequently Asked Questions
How can OCR work without an internet connection?
PrivacyScrubber utilizes Tesseract.js packaged as a highly optimized WebAssembly (WASM) binary. This means the core 'brain' of the optical character recognition runs entirely using your CPU from inside the Chromium sandbox.
Is the Offline PDF feature free?
No, initializing the WASM OCR engine and processing PDFs requires the PrivacyScrubber PRO tier. However, the lifetime tier requires only a single payment.
