Make Scanned PDFs Searchable with OCR Technology

What is OCR?

Optical Character Recognition (OCR) reads text from images. When you scan a document, it becomes a photo — not actual text. OCR analyzes the image and extracts the text, making the PDF searchable and selectable.

When to Use OCR

• Scanned contracts or legal documents
• Photographed receipts or invoices
• Old archived papers digitized with a scanner
• Any PDF where you can't select text
