Tesseract.js is a pure JavaScript port of the Tesseract OCR engine that extracts text from images in over 100 languages. It runs in the browser (via script tag, webpack, or CDN) and on Node.js, supporting automatic orientation/script detection and word/character bounding boxes.

Use cases

• extract text from images in the browser
• ocr scanned documents with javascript
• recognize text in multiple languages from photos
• run ocr on node.js server without native binaries
• get word and character bounding boxes from an image
• real-time text recognition from video frames

When to choose

• you need client-side OCR without a backend or native dependencies
• you need multilingual text recognition across 100+ languages
• you want bounding box data for words, paragraphs, or characters
• you want a well-maintained, widely used OCR library for JavaScript

When to avoid

• you need maximum OCR accuracy on complex documents - native Tesseract or cloud OCR services may perform better
• you need handwriting recognition or modern deep-learning-based OCR quality
• performance on very large batch jobs is critical - native implementations are faster
