2. in the Windows Digital IDs area, you can determine whether your certificate has been recognized. Windows Digital IDs are automatically recognized if a certificate is present on your PC.

Recognize text on pages

PDF-XChange's Optical Character Recognition (OCR) function can also recognize handwritten or scanned text. This is particularly useful for scanned documents, as the content can then be edited and marked up, just as with purely digital PDFs.

2. click on the Recognize text on pages field in the Convert tab.

3. a menu opens. The configuration options are explained below:

• Pages determines the number of pages from the document on which text is to be recognized. With Current, only text on the page you are currently on is recognized. With the Custom option, text within the specified page interval is recognized.
• Subset allows you to extract all pages with an (odd) number of pages.
• In the settings for text recognition, you specify the languages in which text is to be recognized. This is particularly important to ensure that words are recognized accurately. The accuracy is set to Auto by default. If the results are not satisfactory, this can be set to High.
• The output settings offer selectable options for correcting distortions or the option of creating a new document from the recognized text.

4. confirm the selection with OK to recognize the text on pages. The progress is indicated by a loading bar.

5. now open the Content menu on the left-hand side of your window. You may need to expand the menu first to display the options.
