It took just seconds to send my agreement for signature. The customer experience inspires confidence in the security of the transaction and gives a good impression of my company. It is far better than the old - email it, print it, sign it, scan it, email it, "did you get it?"- approach.

Adobe.
,I. Really wanted to make this work for me but I’m afraid it was beyond me.However the trial period which I thought I had cancelled hadn’t gone through then resulted in me receiving a large bill.I panicked thinking they would insist it was to be paid.So I got In touch with them and explained my error.They immediately wrote back and without question refunded my money.It says a lot for a company who responds in this way.I am eternally grateful to them

Great tool
Easy to use and has functionality I need.
Think there is some maximum number of pages you can convert at one time so have to break it up.

First review
It works better than most others I've tried.It is sometimes a bit difficult to navigate as I dont use it too often. I dii have an issue with support, but they did finally undertand my query and they fixed it up, with a very good explanation.

So far so good
So far so good, I would have given it a 5, if downloading my edited documents weren't hidden behind a paywall, but hey, I get it, it is in our nature to capitalize on things where it is impossible to find a solution, few have the solution, so why give it away for free? But yeah, good software none the less.
