How does OCR (text recognition) work?
Quick answer
OCR (Optical Character Recognition) turns images of text — like a scanned page or photo — into editable digital text. It finds shapes that look like letters, compares them to known character patterns (often with AI), and outputs the matching text.
Step by step
- It converts pictures of text into digital text.
- It detects letter shapes in the image.
- It matches them to known characters, often using AI.
- It powers scanning apps, translations, and document search.
