Question 1

How does OCR text extraction work?

Accepted Answer

OCR (Optical Character Recognition) analyzes the pixels of an image, detects the shapes of letters and digits, and converts them into editable text. This tool uses Tesseract.js, an open-source OCR engine that runs entirely in your browser.

Question 2

Is my image uploaded to a server?

Accepted Answer

No. All OCR processing happens locally in your browser using WebAssembly. Your images never leave your device — fully private and secure.

Question 3

What image formats and languages are supported?

Accepted Answer

Supported formats: JPG, PNG, WebP, BMP, and GIF. Supported languages: 100+ including English, Chinese (Simplified and Traditional), Japanese, Korean, Arabic, Hindi, Spanish, French, German, and many more.

Question 4

How can I improve OCR accuracy?

Accepted Answer

Use high-resolution, well-lit images with clear text. Crop to just the text area, ensure good contrast (dark text on light background), and avoid skew or rotation. Screenshots of digital text give the best results.
