In fact, pdf-files that are made by scanning a document, can't be edited, because they don't contain editable text. It's more of a picture than a text file.

Is there any really good and reliable software for editing PDF files in Windows 10 ... ? I tried Soda PDF, but could only edit 2 PDF files !!! So that is not an option. I want to be able to edit the text in PDF files, but keep the formatting and images the same.
