A scanned PDF is essentially just a picture of a document. You can't search for text, you can't copy a sentence, and screen readers can't access the content. It’s a digital dead end. But what if you could unlock that text? That's exactly what **Optical Character Recognition (OCR)** does. It's a transformative technology that turns flat, image-based PDFs into fully searchable, selectable, and accessible documents. This guide will explain how it works and how you can use it for free.

What is OCR and Why Do You Need It?

OCR technology scans the image of your document, identifies the shapes of letters and numbers, and converts them into actual text characters. It's like teaching your computer to read. Here's why this is so powerful:

  • Make Your Archive Searchable: Imagine being able to instantly find any keyword or phrase across thousands of scanned invoices, reports, or historical documents. OCR makes your entire archive searchable.
  • Copy and Paste Text: No more retyping! Extract quotes, data, or paragraphs from any scanned PDF simply by highlighting and copying the text, just like a normal document.
  • Improve Accessibility: OCR is essential for accessibility. It allows screen reader software to read the document aloud, making the content available to users with visual impairments.
  • Enable Editing and Translation: Once the text is unlocked, you can export it to a Word document for editing or run it through translation software.
OCR breathes life into static documents, turning them from simple pictures into dynamic, usable information.

A Note on Accuracy

The quality of OCR depends heavily on the quality of the original scan. For best results, use a document that is clear, straight, and has good contrast. While our technology is highly accurate, it's always a good idea to proofread the results for any critical applications.
