My first time with this App and it seems to be a lot different to Adobe, but easier to operate. I have modified 2 pdf file successfully, and so far (as a new user), not too many 'dropped balls'.

Experienced user back for more
I've used pdfFiller in the past and it has always fulfilled the needs I've had of allowing me to fill in documents just as if I had been sitting at a typewriter (I know I'm dating myself by saying that). The ability to do so and add signatures, save documents to a cloud folder, print the documents when needed, or even have the documents notarized or submitted to the IRS is a major time-saver! I trust that the team behind this product will continue to find ways to save people like me time without costing great sums of money. Do that and I may be able to continue to find room in my tight budget for you!

The application software is a great…
The application software is a great tool. But, when I search for another fillable document of the same, it does not allow me to pull up a clean form fillable document, for example local tax forms. Thank you.

Great software
Great software! Very easy to use and does just about everything you would want a PDF editor to do. The only issue I had was when replacing text the text box deleted the line the text was sitting on and I ended up with a break in the line. Other than that I highly recommend!

EASY and simple
You know i have really enjoyed this app. It's easy and straight forward, I have had loads of applications to fill in as in rental agreements, work forms, drivers licence transfers which all require a signature. I love that i have a signature option and it stores my signatures. So handy and makes filling in application forms a breeze. I even needed my husband's signature and PDF filler made it so simple, i sent him a link and he signed it and it was done. I will continue using this app.
