What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I found that my typing was faster than the rate that the data shows up on the screen. I didn't like that.
My attorney found this link for me, I was unaware that this was a system I would have to pay for. A customer service ticket was generated because I needed help.

THIS APP IS AMAZING ! It has helped me countless times in my personal life and my business ! The template library is huge, I do wish there were more options when it comes to editing a pdf or a library form .

Perfect for paperwork
My overall experience would be that I love it and plan to continue using it going forward in life. It's much easier then printing out paperwork, filling it out, scanning it and sending it back to whomever. Its extremely convenient.
I love most that I'm able to edit any pdf and the save and and either email it or print it. There's even a function to sign the pdf right on the computer. Awesome.
I do not like that it sometime freezes. I could be filling out a form and sometimes it'll freeze and automatically refresh and everything I put in is gone so I'd have to start over. It doesn't happen often but has happened to me before.

PDFfiller Review
I love that I can pull up any pdf form and fill in the blanks. I do a lot of work with the postal forms and this has been so helpful with keeping the information.
I wish you could just double click on a form and open the file, but nothing other than that

Simple tool that increases productivity in office
I'm a software engineer and have to deal with many documents everyday. Having a simple tool that has all the features needed for me to edit and handle all my documents makes my life easier. At the same time it saves me time to look up new tools and ways everyday. The UI is simple and intuitive, and it's easy to attach files, download and share it as needed. Overall it makes me more productive in office.
My favourite feature is the electronic/digital signature feature. As a person in the IT department, I have to work with numerous documents and sign many of them. And this tool made that really easy for me. Also, the signature looks blended out and not out of place. Other than that the merging tool and conversion tool are also very helpful. Depending on my needs, sometimes I can convert a ppt into a pdf for easy access or for sending it to anyone. I also get to attach different pdfs together in whatever order needed.
I don't have any major concerns. The only small problem I've had is regarding character recognition from scanned pdfs. Sometimes it is not entirely accurate. Though it is manageable for me.

What do you like best?
I love the fact that we can collect uploads AND money through filled PDFS
What do you dislike?
The entire site is very confusing and we have a hard time understanding where our active sheets are located within the site. We see things like "documents" and then we make a new template ... then lose which template is live and which one isn't. I also don't care for the fact that we cannot choose to have ZERO color in the field that the customer sees for filling in and I would love to be able to disable the "lock to grid" feature that is clearly on at all times.
Recommendations to others considering the product:
I recommend reading through the site, reading through all the tutorials you can and getting very organized about what you are going to do before getting started.
What problems are you solving with the product? What benefits have you realized?
We no longer have to deal with faxing our documents to customers to fill out, sign and fax back. We just tell them to go to our website . They are also so much more likely to complete the entire process including sending us pictures that we require and we no longer lose the pictures or get confused as to where everything is.

What gives to pdfFiller the advantage over the competition?
pdfFiller is not only a PDF reader and editor. It really is an all-purpose platform for centralized document management. It lets you do every little thing the competitors do and goes beyond that, providing benefits you’d typically get in a number of different tools. With pdfFiller, you get all you will need for setting up efficient document workflows.
Simple document management'
There is no need to download or install anything at all. Just register an account, upload your documents, and begin working straight away: merge, edit, convert, rearrange, annotate, and much more you can do to document the way you need. Then, send copies through email, fax, SMS, or even USPS.
Unparalleled time-efficiency
Unlike quite a couple of our competitors, we value your time and want you to become as productive as you can. Generate templates for your most frequently utilized documents to avoid retyping information, fill out up to 1,000 uniform documents at a time, or extract data from forms in bulk.
Extensive library of templates and forms
Need a standardized, fillable form here and now? Find it in the pdfFiller online library. Or develop a form from scratch by just adding fillable fields in your document. You can host or share forms in seconds, enabling anybody to fill them out online from any device.
Very simple e-signing and tax reporting
Thanks to the integrated signNow functionality, you can e-sign documents on the go, collect signatures from a number of persons, track the signing progress of a document, set a signing order, etc.
Security and plenty of storage space
We care about the safety of one’s assets and believe that storage limits shouldn't distract you out of your function. That’s why pdfFiller allows you to keep your documents protected in the cloud with unlimited storage. On top of that, you can protect sensitive information with two-factor authentication and passwords.
