1. How to Download and Install OCR

2. How to OCR PDFs

Once installed, close the window and navigate to the same Tools option for accessing the OCR tool across UPDF. As it opens up, it will provide you with 3 different options of Document Type, which include Editable PDF, Text and Picture Only, and Searchable PDF Only.

• Editable PDF: This mode saves recognized text and pictures. A PDF file of this type has a relatively small size. Visually, this document may differ slightly from the original.
• Text and Picture Only: This mode keeps the background image and illustrations of the source document and overlays the recognized text. Usually, such PDF files are larger than those created using the Text and pictures only mode. Visually, this document may differ slightly from the original.
• Searchable PDF Only: In this mode, the page image is retained, while the recognized text is placed into an invisible layer underneath the image. Visually, this document is nearly identical to the original.

Define a proper Document Language with the option of 38 different languages across the drop-down menu. This provides UPDF with a better ground for recognizing text accurately across the document.

Work over the Page Range and choose the pages manually or extend the menu to select All Pages, Even Pages, and Odd Pages options from the list. Once done, press the Convert button to execute OCR across
