Com 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
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
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
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
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.
