I love this PDF editor. Two questions: 1. Do you have an off-line version? 2. Do you have a function to edit existing text instead of erasing the text?

All PDF tools in one app My overall satisfaction about that app is a lot, it's just great tool for everyone, for students and also employees as well, at any time people can make change in their document and send it wherever it's needed. That's basically great app, because you can solve all document issues in one app, scanning, adding image to the document putting dates, even signature, saving as pdf, or word or excel, sending to email, printing and etc. which help users to save more time. I remember I faced problem while logging in, actually I think to login for that kind of program is something extra.

Easy And Fast PDF Form Filling Software! Works with all types of devices, so I can prepare a document for signature quick and right where I am. Pricing is very fair. It is sometimes a little slow and there is a bit of a learning curve but once those are overcome, it is practically flawless.

I used their services for 1 year I used their services for 1 year, all great services and does exactly what you would expect. Also they are very fast to respond to customer's emails. They also gave me a very fast refund within few hours of requesting it as my subscription was auto renewal and i no longer needed that second subscription. Highly recommend and can be trusted with your money 100%.
