tesseract.js โ Pure JavaScript OCR for more than 100 Languages
Overview
Tesseract.js is a JavaScript library that enables Optical Character Recognition (OCR) in the browser and on Node.js, supporting over 100 languages. It wraps a WebAssembly port of the Tesseract OCR engine, allowing developers to extract text from images without relying on external services.
Key Features
- Supports over 100 languages for OCR
- Works in the browser and on Node.js
- Easy integration with Webpack, ESM, and CDN
- Real-time video recognition capabilities
Use Cases
- Web developers extracting text from images for search indexing
- Mobile app developers integrating OCR for document scanning
- Data scientists preprocessing image data for machine learning models
- Accessibility tools for converting images to text for visually impaired users
Advantages
- Pure JavaScript implementation, no need for server-side processing
- High language support for global applications
- Open-source and actively maintained
- Real-time processing capabilities for dynamic applications
Limitations / Considerations
- Does not support PDF files
- Does not modify the Tesseract recognition model for improved accuracy
- May have performance implications for very large images or high volumes of requests
