What is OCR (Optical Character Recognition)?
OCR (Optical Character Recognition) is a technology that converts images containing text into machine-readable, editable text. It works by analyzing the visual patterns in images to identify and extract characters, words, and sentences. Modern OCR systems use advanced AI and machine learning to achieve high accuracy across various fonts, languages, and document types.
Our OCR tool combines advanced AI technology with user-friendly controls to provide professional text extraction capabilities. Whether you're working with scanned documents, photos of text, or handwritten notes, our tool can convert them into searchable, editable text that you can use in any application.
