With scanned files, the content of the document is available as a large graphic. As a rule, such documents do not contain text. In order to change this graphic, either use a graphic editor or perform OCR using the PdfEditor for the image contained. For this, right-click on the image and select the command "Text recognition with OCR". In the next window, select the desired OCR software, specify the document language and select how the recognised text is to be displayed in the PDF. If the PDF is to be edited, we recommend the text display option "Visible & delete image". "Invisible" is recommended for archiving purposes. Please note that the quality of character recognition (OCR) depends to a great extent on the quality of the scan.
