About This Tool

What is OCR Text Recognition?

OCR Text Recognition extracts readable text from images using optical character recognition powered by Tesseract.js. Upload a photo of a document, screenshot, receipt, or handwritten note, and get the text content you can copy, edit, and use.

Supports 12+ languages including English, Chinese, Japanese, Korean, Spanish, French, German, and more — all processed locally in your browser.

Common Use Cases

  • Document Digitization: Convert printed documents, receipts, or letters into editable text
  • Screenshot Text Extraction: Pull text from screenshots of web pages, error messages, or chat logs
  • Translation Prep: Extract foreign-language text from images for translation
  • Data Entry: Quickly digitize text from forms, invoices, or business cards
  • Accessibility: Make image-based text accessible to screen readers

Privacy-First OCR Processing

OCR runs entirely in your browser using Tesseract.js (WebAssembly). Language models are downloaded once and cached locally.

  • Your images and documents never leave your device — critical for sensitive documents
  • No cloud API calls — zero data transmitted during recognition
  • Works offline after language models are cached
  • Ideal for confidential documents: medical records, financial statements, legal papers
