What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
I enjoy the ease of completing the forms, printing and saving the documents. I expected to be billed at the 65% off rate for one time use, annually, but somehow was charged the $72.00 annual renewable rate. I will now have the inconvenience of having to cancel the subscription, since this is the last time I need to perform this function.

I really like the ease in using this program. I have tried other PDF software but find them all very awkward to use. I am just not sure about the pricing. I assume I signed up for 12 months? This is a great program and I don't have to hand print documents when most documents are PDF anyway.

Works smoothly and easy to use. Customer support tried to help with a "glitch" I have still not resolved. Works on my iPad perfectly but pull my docs up on desktop just sits there thinking to no end. I've just used on iPad soley since problem came up.

What do you like best?
The best feature of PDFFiller is its ease of use, whether it's editing documents, signing documents, and then being able to access your documents anywhere by logging onto the site, as opposed to being constrained if you don't have your computer files with you.
What do you dislike?
Some of the option menus should be improved upon, especially as far as layout and ease of finding what you need, it's a bit counterintuitive though with experience that becomes less of an issue.
What problems are you solving with the product? What benefits have you realized?
Signing PDFs with ease. Being able to access and edit a pdf no matter where I am as long as I have internet access, even if I don't have my computer with me and/or don't have access to my cloud storage.

A good product A good product. You'll have to sign up for the service if you want to save your doc, but they have a free thirty day trial, so it's not so bad. Allows you to edit documents in a relatively user-friendly and intuitive way. No real complaints, but it also didn't blow my socks off or anything, so 4/5.

Customer Service Online messaging rep.. I got ahold of customer service messaging system and told them my issue. Within 5 minutes I had someone already solving my issue and refunding me. The fact that their customer service was so on point with having no way to call. Actually impressed me. Thank you guys. You have my recommendation.

Great PDF Very easy to use! Updating documents quickly is really helpful and saves me time in my practice. It's great to have the app in case I am not in my office when a change is needed. There are a few glitches. For example, in order to save a document you have to remember to duplicate it. The emailing feature can be glitchy at times.
