OCR
Image-to-text conversion
OCR stands for optical character recognition—technology that converts images of text into machine-readable text.
A scanner or camera captures a document, and OCR software identifies the letters and words: The OCR struggled with the faded typescript.
Quality varies with image clarity and font complexity.
OCR enables searchable PDFs and digitization of printed archives.
