How Does OCR Work?

1. Scanning – The document is scanned using an OCR-enabled device (scanner or camera).

2. Text Detection – OCR software identifies characters, words, and symbols in the scanned image.

3. Character Recognition – It analyzes the shapes of letters and converts them into digital text.

4. Output Generation – The recognized text is saved in formats like Word, PDF, or plain text.
