I had to use pdf Filler to fill out some online divorce documents, and after being initially upset at having to pay for a monthly subscription for a year to print it (very upset), I sucked it up, signed up, and have never stopped using it. Just discovered the eraser...very cool.

The PDF filler provided an easy and efficient way to complete my PDF documents. It allowed me tailor the form to completely explain its intended purpose.
JACK P
some forms are not as well created. would be nice to be able to tab between fields. or when clicking in fields that should all be within the same horizontal line it would be nice if they automatically lined up rather than having to be moved like individual text boxes.

Fantastic customer service For some reason I needed this and only once. I got the free trial and then forgot all about it until $115.00 was collected from my account, shock horror. All I can say is you have fantastic customer service, I explained my situation and a refund was issued that same day. Both friendly and speedy. Ace by name and by character, much appreciated. 1 star deducted as I would have liked a reminder email when the free trial was coming to an end.

User interface can be better This is a pretty good website to merge pdfs. Overall has everything you need. I do believe the user interface can be easier to use for those who aren't as tech savvy.

Absolutely worth it! Wonderful program. Slight learning curve, but then it's off to the races. Worth it if you are editing PDF's on the daily. Great save, download and share options all at once. Thank you for a great program!!

Actually, I just came across this with a standard google search. I was using Adobe Illustrator and it was overkill and took ages to load every time I just wanted to update a PDF file. This has been awesome and so easy and quick to use! The 'Signature' option was a bonus as well!
