Excellent tool, very useful and easy to use
In my work we use a lot of PDF for contact with the client and the truth is that it is useful to have such a tool to make it quick and easy; It's something less to think about.
The best thing about this tool is that it solves a basic problem with the PDFs we receive: editing them. It is also very easy to use, saves a lot of time and has the possibility of adding a digital signature to each document.
Some form formats are more complex to edit and the tool gets confused, but it happens with all other tools.

So far
So far, so excellent. User experience takes a little getting used to, but a quick google shows you how to do it. And I haven't found anything yet that it wont do. Great tool. Used it for about 40 documents so far. Splicing things together, re-wording and cutting and changing dates. Basically editing everything imaginable in pdf.

Legal and Ethical Considerations in Editing Signed PDFs Of course, to ensure the edited PDF is valid, it must be digitally signed again. In short, there is no good way to edit a signed PDF without the original signature being invalidated, and this is by design.
Can a digital signature be tampered?
Once the signing process is complete, some providers may digitally seal the documents using Public Key Infrastructure (PKI), an industry-standard encryption management technology. This seal indicates the electronic signature is valid and that the document hasn't been tampered with or altered since the date of signing.
Is there a way to edit a digitally signed PDF?
The most important point is that a digitally signed PDF document cannot be meaningfully altered without losing its validity. Methods to edit a signed PDF either digitally “print” the PDF as an image and then re-convert it back to a PDF (creating an identical, unsigned PDF in the process).
Can a digital signature be changed?
To change Digital Signature Certificate (DSC) details, the organization need to follow below procedure *. 1) Login with user ID using existing Digital Signature Certificate. 3) Fill the required details of the DSC, which needs to be mapped with your user ID. 4) Select the renewed/Changed DSC.
