I wanted to be able to duplicate a filled form and make a couple of changes. Then save with a new name. I did download and rename before I did this. glad I did. PdfFiller overwrote the file. All is well since I downloaded the original.

3 times I have contacted PDFFiller support and every time they have responded in less than 30 minutes. This is the fastest support service I have ever encountered.

Unfortunately I paid for PDFescape before I found you. I subscribed to the Ultimate - it was very user unfriendly with absolutely no online tutorials or help - and I am no novice, I have designed and published several of my own websites. I really think yours is great and have had real a good experience working with setting up my contracts with it. Thanks! Sam

Does everything a PDF editor should, except when a signature placement is required. The signature is squeezed into a field that miniaturizes the graphic.

I have had a great experience thus far… I have had a great experience thus far in my free trial. I have been able to merge documents to create a continuous flow, create signature stamps and fill out fillable pdfs' for my work. This is a great product!

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%.

I received an auto-renewal subscription for our organization that was initiated by a previous officer and simply emailed my request for a refund and cancelation. I was contacted almost immediately by a **** ***** from pdfFiller/AirSlate that verified my information and resolved my problem. I had the money credited back within a few days. Thank you!

Communication & follow through on point. Only ever used Adobe in the past. Found this affordable option. It is fantastic. User friendly and an effective app. I applied for a rental with a heap of forms to fill out and now our family are living in it. I accidentally signed up for the 1year subscription. I contacted the help desk, and advised that I only wanted to use it during the trial period for a purpose and happy to pay for one month. Their reply communication was quick and on point. They summarised and actioned exactly what I requested. Only charged me $30 for the month, refunded the difference $114 and cancelled my future subscription. I would happily use this again. Thank you very much.

This product is very easy to use and I… This product is very easy to use and I am impressed with the various toll available to make the changes to the PDF files.The service and backup provided by the support team is excellent. I cannot fault their response times (within 20 minutes of my email) and they were attentive to my concerns and resolved the invoice issues immediately. Totally would recommend this to anyone.
