What is a Scanned PDF?

A scanned PDF is a document that has been created by scanning a physical piece of paper. This process captures the image of the document and converts it into a digital format. While scanned PDFs are useful for preserving the appearance of the original document, they often lack searchable text. This is where converting scanned PDFs to text becomes essential, allowing you to edit, search, and manipulate the content within these documents.

Why Convert Scanned PDFs to Text?

Converting scanned PDFs to text offers numerous advantages:

  1. Enhanced Searchability: By converting to text, you can easily search for specific information within the document, saving time and effort.
  2. Editability: Text conversion allows you to edit the content, making it possible to update information or correct errors without needing to rescan the document.
  3. Accessibility: Text-based documents are more accessible for individuals using screen readers or other assistive technologies.
  4. Data Extraction: Extracting data from scanned documents becomes straightforward, enabling you to compile information for reports, presentations, or databases.

How Does the Conversion Process Work?

The process of converting scanned PDFs to text typically involves Optical Character Recognition (OCR) technology. OCR is a software application that analyzes the shapes of letters and characters in an image and converts them into machine-readable text. Here’s a step-by-step breakdown of how this works:

  1. Scanning the Document: Start by scanning the physical document to create a PDF file.
  2. Uploading the PDF: Use an OCR tool to upload the scanned PDF.
  3. Character Recognition: The OCR software processes the image, identifying characters and converting them into editable text.
  4. Review and Edit: After conversion, review the text for accuracy and make any necessary edits.
  5. Saving the Text: Finally, save the converted text in your desired format, such as .txt, .docx, or .pdf.
