                     If recognition is run on images, they will be converted to PDF documents. More specifically, a page will be generated for each image in the PDF document, with this page containing the original image and a text layer with the recognized text.
                     Character recognition on PDF documents will only work with documents that do not contain text already. Normally, these will be documents that were generated by scanners and that only have an image per page in the PDF document.
