The App is clunky and not easy to use and annoyed that when trying to combine different documents have to upgrade to the next level.
So overall good product on laptop, poor app and disappointing capabilities v price.

Great product...relatively easy to use
Great product...relatively easy to use, especially if one is familiar with this type of document editing app. I am please with how much of a time-saver it is. I couldn't give 5-stars because the cost of the "Full Version" is really too expensive for me, but other than that, it's a very handy tool.

Amazing Customer Service
While I was reviewing a couple of unauthorized charges on my PayPal account I noticed they were from PDF filler. Upon further investigation as to what PDF filler is, I realized that this was due to something a professor from a course I had taken last year had required the class to use to complete an assignment. He assured us that though we may need to put in our personal information, the service we were using would be "free". I did not realize that “free” was then turned into a renewable purchase fee. I contacted PDF filler to dispute the charges and explained what had happened. This company responded to my email with genuine kindness within a couple of hours to assist me with providing a refund upon receipt of a response providing verification information. I emailed them the information and again, within a couple of hours, I received a response that I had been refunded the fee. I appreciate how professional, considerate, and amazingly responsive this company has been- the whole process was quick and painless and I will certainly consider using PDF Filler in the future should I need such a service!!

Their Customer service is superb.
Their Customer service is superb.
I was charged for a subscription which was, to me, erroneous as I had merely tried the sofware and immediately cancelled.
But on contacting customer service I was pleasantly surprised at the speed of their response and at the total refund with no qustions asked.
They go beyond the call of duty, many thanks.

I've signed up for the 30 days trial to fill out an important form via PDF file. Work & covid has been occupying me so much that I forgot to cancel my free trial. I sent in a ticket and spoke to a staff named Phoebe. She replied extremely fast, understood my situation and proceeded to help me with my refund.
I am very satisfied with the outcome & would recommend pdfFiller to everyone as their customer support is top notch.

mostly good. Had trouble one day but it looked like it was site-wide. It was fixed by the next day. Would like to better understand how to capture documents and transfer to other files etc.

What gives to pdfFiller the advantage over its competitors?
pdfFiller is not only a PDF reading or editing tool. It is an all-purpose platform for centralized document management. It permits you to do anything the competitors do and goes far beyond that, offering features you would generally locate in a number of separated tools. With pdfFiller, you get all you will need for establishing effective document workflows.
Straightforward document management'
There is no need to download or set up anything at all. Just set up an account, upload your documents, and commence working right away: annotate, convert, split, rearrange, edit, and much more you can do to document the way you would like. Then, send copies by using email, fax, SMS, or perhaps USPS.
Unparalleled time-efficiency
In contrast to loads of our competitors, we respect your time and want you to be as productive as you can. Produce templates for your most often used documents to prevent retyping information, fill out as much as 1,000 uniform documents at a time, or extract data from forms in bulk.
Expansive library of forms and templates
Need a standardized, fillable form right here and now? Get it within the pdfFiller online library. Or create a form on your own by basically adding fillable fields to your document. You can host or share forms in seconds, allowing anyone to fill them out online from any device.
Simple e-signing and tax reporting
Thanks to the integrated signNow functionality, it is possible to e-sign documents on the go, collect signatures from several people, track the signing progress of a document, set a signing order, and many other things.
Security and plenty of storage space
We care about the security of the assets and believe that storage limits shouldn't distract you out of your work. That is why pdfFiller enables you to maintain your documents safe within the cloud with limitless storage. On top of that, you are able to protect sensitive data with two-factor authentication and passwords.
