pdfFiller scores top ratings on review platforms
It is a challenge to adapt to different methods in so many computer programs factoring in hardware and software and my limited patience. As with many other computer related things we need to keep trying. I am not used to doing things a certain way which may work wonderfully for others and they can't understand my way.
A nice format that allows a professional presentation but the data input is still tedious and could be streamlined. All things considered, I'm satisfied with the product.

I just started using this tool and I am impressed with the ease of editing a PDF document. I have yet to master lining up my edited text with the document. I am able to edit the document enough to be useful.
Slight misunderstanding promptly resolved
There was initially a slight misunderstanding, however, I was lucky enough to get Dee again when I reopened the chat. She had thought that I just wanted my subscriptions automatic payments cancelled. Really I wanted the payment stopped and the subscription cancelled. Thankfully she worked up until the last minutes of her shift to help me. She was excellent help!

Can a digital signature be modified?
Once a PDF has been digitally signed, it is usually impossible to edit without compromising the signature. And it's precisely the purpose of an electronic signature not to be able to tamper with a signed document!
Is it possible to edit a digitally signed PDF?
If you received a PDF digitally signed by others, you can sign it, but can't edit it. While signing a PDF, if the signer chooses to lock the document after signing, the document becomes read-only for everyone, including the signer.
