Professional PDF Text Extraction Without Privacy Compromise
Extracting text from PDF documents is essential for accessibility, data entry, and document analysis. However, most online OCR tools present a significant security risk. They require you to upload sensitive files—containing financial data, personal IDs, or medical history—to their servers. DocuStitch eliminates this risk.
Our tool uses Tesseract.js compiled to WebAssembly (WASM) to perform OCR directly in your browser. When you upload a file, it never leaves your device. The Tesseract.js engine analyzes each page, identifies text regions, and extracts characters using advanced pattern recognition. This ensures your documents remain 100% private and the process is dramatically faster than cloud-based alternatives.
Our OCR engine supports multiple languages and can handle complex layouts including tables, columns, and multi-column documents. The extracted text maintains the original document structure for easy post-processing.
Tesseract.js WASM
The entire OCR engine runs inside your browser using near-native WebAssembly performance.
Privacy Focused
Zero records. Zero logs. Zero uploads. Your sensitive documents stay exactly where they belong: on your machine.
Multi-Language Support
Supports 100+ languages including English, Spanish, French, German, Chinese, Japanese, and more.
Instant Results
