Understanding OCR Technology: How to Extract Text from Scanned PDFs
Have you ever needed to edit a scanned PDF or copy text from a printed document? That’s where OCR comes in. OCR stands for Optical Character Recognition — a powerful technology that converts printed or handwritten text in scanned images or PDFs into editable and searchable digital text.
What is OCR?
OCR (Optical Character Recognition) is a process that analyzes scanned images and identifies characters, words, and numbers. It then transforms those into digital text you can copy, edit, or search.
For example, if you scan a physical invoice, OCR will detect the text in that image and output a machine-readable format like DOCX, TXT, or searchable PDF.
Why is OCR Important?
- Edit scanned documents: Turn paper-based forms or printed documents into editable files.
- Search within scanned PDFs: Make lengthy documents searchable with ease.
- Save time: Avoid retyping entire pages manually.
- Preserve data: Digitize old printed files and keep them safe forever.
How Does OCR Work?
OCR engines analyze the structure of the image or scanned document by identifying light and dark areas. The dark areas are recognized as characters, which are then matched with a database of fonts and symbols to determine the correct text.
Modern OCR software also uses AI and machine learning to improve accuracy — especially for handwriting and low-resolution scans.
Common Use Cases for OCR
- Converting scanned PDFs to editable Word or Text formats
- Digitizing books and handwritten notes
- Extracting data from receipts, forms, and ID cards
- Enabling text search in image-only PDFs
