What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
This program is very useful for filling out tax forms. Although my returns are not complicated, getting the credit that I am due for foreign taxes is too much for tax programs like HR Block and too much for most accountants. I have returned to my old habit of doing my returns manually. This PDFfiller program makes it feasible.

It's the easiest pdf editor that I have ever used. I have 27 years experience in the IT Industry & I'll be recommending this one to my commercial customers

I discovered PDFfiller.com during a Google search. I wanted to fill in a job application professionally instead of hand written. How very nice of them to let me try it for free. I've tried other free services in this same manner and they were just too difficult to work with when I'm in a hurry. With this program, I clicked on the application, it downloaded, and I started filling in my info! No learning curve AT ALL.

A reliable and quick to use PDF signing and editing platform
Quick and easy signing for PDF forms, especially on mobile devices.
PDFfiller is web-based, so it's easy for me to access on my phone if I need to quickly sign or edit a PDF file.
Additional features in the paid subscription model (more editing options), would convince me to sign-up for the paid versions of the software.

First time trying this app/website. So far it has worked perfectly for what I needed it to do. So only time will tell in order for me to find out if it'll work good for any other different edits I may need in the future. Only downside so far is when I first used it I just used it on their website and after I finished my first edit I went and searched pdffiller in the app store and I downloaded the app and I started my second edit thru the app. I noticed that when editing in/thru the app I didn't have at least 1 of the features that I had/used when I was doing my first edit so I ended up closing the app and finishing my second edit thru their website bcos the main reason I needed an edit document app was so that I could delete the pages from a few documents that werent needed to shorten the document itself and in the app it wouldn't let me delete any of the pages. The only option the app would give me that had to do with the pages was if I wanted to change the order the pages were originally in then I could choose what order I wanted the pages in but there wasn't any delete pages option but other then that I love pdffiller so far! Although I really wish/think the account subscription price in order to actually use the app should be cheaper. Which for the cheapest/bare minimum options they give you is $8 monthly which I think is expensive considering. I personally think it should be at the most $4 monthly. Or have an option where it's $2 monthly and then depending on how often you use it and what you have to use it for, then there should be a small $.75¢ - $2.00 charge/fee depending on what you'll be editing and how many tools you'll be using and then that should be how the company decides how much to charge per edit and then the customer can decide what exactly they want to do for edits and what they don't etc. I don't know I just think $8 monthly is really high especially for someone like me that will likely only use it a couple times a year and I'd be more likely to keep the subscription and not just do the free trial if it was lower then $4 a month otherwise it's not worth it for me to keep the subscription after the 30 day free trial but that's just me personally

I liked the clear simple explanations.and the fact that it stops you from clicking on anything until it has explained the basic functions of the key attributes. For some of us who think they can probably figure it out on our own the little speed bump and wake up call save a LOT of time.
