pdfFiller ranks among the best

pdfFiller is rated 4.6/5 stars on 125,000+ G2 reviews.

For the most part this is an easy and reliable program to navigate. Some forms expect utilization of the text tool which does not always lend to professional format or uniformity. I am unclear whether this is a function of PDFfiller or the form itself.

It is somewhat confusing at first, but after learning the program it is very helpful and convenient to use! I enjoy all of the different options regarding the tools to fill out a PDF, for me it was a rental application for an apartment that i needed to fill out. The one thing I did not like is that after i had filled out my entire application via the pdffiller app, i could not e-mail the pdf until i paid for a plan. Somewhat disappointing, but regarding the program it is a good one.

easy, well organized, love the signature options especially. Ability to share and distribute is a fine function. I live in Germany and did my girlfriends USA taxes all electronically and send to her to sign and submit.

Honestly, I used this service for one day. I did the whole hoopla, signing up for the service, getting my PDF's and documents taken care of, then went in to cancel my free trial. Well, something went wrong, and I was charged for a full year that I didn't want. But the reason they get 5 stars instead of zero-- they voided the charge same day that I emailed them. They weren't worried about pinching pennies, they were worried about being a good business and doing the right thing. That's a 10/10 in my book. Honestly, I have them bookmarked on my webpage so that if/when I need their services again, I'll definitely be going back!

Great, this time so far. I used the program a little over a week ago but my documents were messed up because I was not told I had to pay first in order to save or print the document. I had to create it all again. It was the same one as this now, 821 ssa form. It took me hours to get as far as I had.

Great Customer Service! I hadn't realized That I was getting billed, and for 9 months, I was paying for a service I only used once. Ryan helped me over the customer support, and helped me find the email I had used (it wasn't my main account), and helped me cancel the subscription for a full refund. He was super nice about it to, so I figured I'd review him.
