I'm a layman when it comes to figuring out things.
I'm a layman when it comes to figuring how do create things on the Internet. It's always cool when I can chat with someone who can figure out what I'm trying to do and have the patience, at least I think they have the patience when I'm going round and round with them on each step in getting my dilemma resolved. As before in chatting with someone at the chat desk, they have always been professional.

They were super helpful to me when I accidentally subscribed. They voided the transaction and were understanding. I really appreciate this because there are too many other automatic subscriptions that would not have been as forgiving.

How do I edit an already signed PDF?
Can I edit a PDF that I signed? If you're the only one signer, you can remove the signature and then work on the document or edit the source document. To remove your signature, right-click the signature and then choose Clear Signature.
Why can't I edit my PDF file?
There are several reasons why you can't edit a PDF document. You have a scanned document in this case, you need to perform OCR to convert it into an editable format. Your PDF app doesn't support editing for example, not every PDF reader allows you to change a text in a PDF file.
How do I enable editing on a PDF?
Go to File>Open.
Select the Edit PDF tool in the right pane.
Click on the text or image you'd like to edit.
Can I edit my own PDF document?
While you can't edit a PDF file directly in PDF format in Word, we'll use a workaround that lets you make edits and still have a PDF when you're done. In Word, head to File > Open and then navigate to the PDF file that you'd like to edit. Word will automatically convert the PDF into an editable Word document.
How can I edit text on a PDF?
Choose Tools > Edit PDF > Edit. Outlines identify the text and images you can edit.
Select the text you want to edit.
Edit the text by doing one of the following: Type new text to replace the selected text, or press Delete to remove it.
