Text extraction is the process of automatically pulling readable, editable text from un-editable sources like images, scanned PDFs, screenshots, or physical documents. It converts visual or locked data into machine-readable text files, allowing users to search, copy, edit, and analyze the information effortlessly. Key Technologies Behind It
Optical Character Recognition (OCR): The primary technology used to identify shapes, letters, and numbers from an image or flat file and translate them into digital text characters.
Machine Learning / AI Extraction: Advanced tools go beyond basic character recognition to understand document layouts, tables, and complex hierarchies. Modern AI platforms can accurately extract specific key-value pairs (like totals from invoices) or interpret handwritten notes. Popular Tools to Extract Text How to Extract Text with Text Extractor
