Как это работает
OCR (Optical Character Recognition) here uses the open-source Tesseract engine — the same engine Google has maintained for decades — compiled to WebAssembly so it runs natively in your browser.
- 1The OCR engine downloads as WebAssemblyOn first use, Tesseract.js loads as a WebAssembly module (~3 MB). It runs inside your browser like native code, with no plugins or extensions needed.
- 2A language model downloads for your chosen languageEach language has its own trained model (~5-15 MB each, depending on script complexity). You pick the language; only that language's data downloads. Your browser caches it for future use.
- 3You select or paste an imageThe image is read into your browser's memory. Tesseract analyzes the pixel data to identify character shapes — no upload, no API call.
- 4Text is extracted with a confidence scoreFor each detected word, Tesseract assigns a confidence percentage. High contrast and clean fonts give 95%+ confidence; messy handwriting or low resolution drops it.
Your images stay on your device — not even temporarily uploaded for processing. Safe for ID documents, contracts, medical paperwork, or any text with sensitive content.
