Como funciona

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.

  1. 1
    The OCR engine downloads as WebAssembly
    On 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.
  2. 2
    A language model downloads for your chosen language
    Each 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.
  3. 3
    You select or paste an image
    The image is read into your browser's memory. Tesseract analyzes the pixel data to identify character shapes — no upload, no API call.
  4. 4
    Text is extracted with a confidence score
    For 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.
