Question 5

What is OCR?

Accepted Answer

OCR (Optical Character Recognition) is a technology that converts scanned images or image-based PDFs into searchable and editable text. This tool creates a selectable text layer in your PDF, making the text searchable and extractable.

Question 6

When should I use OCR?

Accepted Answer

Use OCR when you have scanned PDFs, image-based PDFs, or PDFs created from photos. OCR creates a text layer that makes the text selectable, searchable, and extractable, which significantly improves text extraction accuracy.

Question 7

How does OCR improve text extraction?

Accepted Answer

OCR analyzes the visual content of your PDF pages and creates a selectable text layer by recognizing text characters, even from scanned images. This text layer makes it possible for text extraction tools to find and extract text that would otherwise be invisible to standard extraction methods.

Question 8

What does 'selectable text layer' mean?

Accepted Answer

A selectable text layer is an invisible layer of text that OCR adds to your PDF. This layer allows you to select, copy, and search text in the document, and enables text extraction tools to read the content. Without OCR, scanned PDFs are just images with no extractable text.
