What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
It's pretty good. There is a delay from when I type till when the text appears in the text box.Also, I don't like have each field with a help box. I know I can X it out but it gets in the way when I want to go fast. I do like that it goes automatically from one field to the next such as with the dates.

So far, so good. I don't like that it seems to lose its connection frequently and I have lost data a time or two but that may be a function of where/what I work on. Otherwise, fair deal for the price.

Works fast and easy Works fast and easy, great service!I had signed up very briefly to edit some pdfs for work. The program worked smoothly, but then I foolishly forgot to end my membership, and was billed for a years' worth of their service, which I did not need. Their customer support was top-notch and had my problem resolved in just a few minutes. I'd recommend them for anyone looking for a company that is responsive to their customers.

Very pleased with the customer service I recently moved from Nitro to pdfFiller and just had my first customer service interaction. I was very pleased with how promptly I received answers and how well my issue was resolved. Off to a very good start!

Helpful for Digital Signature Overall the PDF filler is amazing and free! These days, a lot of people don't have printers and scanners. Also, a lot of us are working from home. This software makes it possible to sign documents without printing and scanning. My least favorite thing is that you have to create an account to save your document. It would be nice to not have to provide my email to save the document.

working great so far, any difficulties are due to my lack of knowledge. My only suggestion is to hire one really dumb guy, and make it so its easy for him. Would you like me to send my resume'?
