I'm loving everything and I like how I can do so much without printing, then write your info, then scan to your pc, then email to an individual or group. This is way, way faster.

It has been very helpful. The user interface is not difficult to navigate. I am cancelling only because I do not have the volume of documents to warrant the cost. But when this changes I will certainly return.

I have only just started using PDFiller.com and I am very happy with the product. My only compliant is that I was forced to subscribe to it without the option of a free trail etc When I did a search on the web for a free PDF Editor, PDFiller.com was one of the websites that popped up, I edited my document (which was a theory paper that I had already spent hours on !!) and when it went to saving it I could not without paying for service... so not a free PDF editor!!! And you can not subscribe month to month, you had to pay for a full year. I know that is business but very deceiving!

FPDF FILLER EXCELLENT TOOL. IT WOULD BE NICE IF WE COULD ADD A PAGE TO AN EXISTING DOCUMENT SO THAT IT ALSO BECOMES PART OF THE ORIGINAL DOCUMENT. IF THE THERE ARE FOR EXAMPLE 10 PAGES UPLOADED AND I WANT TO INSERT A PAGE IN FRONT OR IN BACK OF SAY PAGE 7 THEN I COULD MAKE IT A COMPETE DOCUMENT WITH THE PROPER INSERT. OR IF I COULD DELETE A PAGE FROM THE 10 PAGES AND INSERT A NEW PAGE IN THE PROPER INSERTION POINT.

Paul was able
Paul was able, after me explaining my issue, to completely solve my problem! He was brilliant!
Anthony and I had a conversation as well but I needed to cut the call short, therefore, no feedback form was sent for him. He too was extremely helpful!

What is a PDF certificate?
A certificate stores the public key component of a digital ID. For more information about digital IDs, see Digital IDs. When you secure a PDF using a certificate, you specify the recipients and define the file access level for each recipient or group.
What is a PDF signature?
An electronic signature, on the other hand, is merely an image of your signature overlaid on top of a PDF document. You can do it with all kinds of apps, and it's what most people will require when they send you a document to sign. Send them a PDF file with a digital signature, and they won't know what to make of it.
