I scanned a document on my HP Envy 5530 and I was hoping to edit it one of the free or nearly free PDF editors. I've tried documentcloud Adobe and one other. I can erase some text and type in some new text, but it's next to impossible to match the original text in position or especially appearance. I'm guessing that the "PDF" captured from the scanner is not fully editable? Ultimately what I wanted to do was click on the text in the scanned PDF and change it.
Hope you are doing well. As described you want to edit the PDF using free PDF editor.
Would you mind sharing the appliation you are using to edit the PDF created from scanner? Assuming you have Acrobat Reader DC (Freeware application) The Edit PDF function is available in Adobe Acrobat Pro DC (Paid subscription).
