OCR (Optical Character Recognition) is the process of detecting and extracting written or printed text from an image. This tool uses Tesseract.js, a WebAssembly port of Google's Tesseract OCR engine.

What languages are supported?

English, Spanish, French, German, Chinese (Simplified), Japanese, Hindi, and Arabic. Each language requires a small language data file that is downloaded on first use and cached by your browser.

How accurate is the OCR?

Accuracy depends on image quality. Clear, high-contrast printed text on a clean background achieves 95%+ accuracy. Handwriting, unusual fonts, low-resolution images, or heavy compression reduce accuracy significantly.

Does the image get uploaded anywhere?

No. Tesseract.js runs entirely via WebAssembly in your browser. Your image and the extracted text never leave your device.

What image types work best for OCR?

High-resolution screenshots, scanned documents at 300 DPI or higher, and photos taken in good lighting with minimal blur produce the best results. Avoid heavily compressed JPEGs for text extraction.
