What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
ITS PRETTY GREAT, THERE ARE A FEW FEATURES I WOULD LIKE, INCLUDING AN ONLINE MANUAL AND THE ABILITY TO MOVE TEXT BOXES ONCE THEY ARE FILLED OUT. THERE COULD ALSO BE AN ABILITY TO PAY PER FORM AS I PROBABLY WON'T BE FILLING OUT PDFS FREQUENTLY ENOUGH TO JUSTIFY MONTHLY PAYMENTS.

for the most part, all of the documents that i need have been found on PDF filler. I did have to find the 2016 1099 int form on another site, but at least i found it. This service has saved me a bunch of time by not having to type these forms on a typewriter.

I mainly use it to edit papers for my teaching position; it's been very useful to not alter the original format while adding my view point freely on the document.

My only two complaints are the price and the fact that if you only want one page out of a file with a lot of pages... it seems the only way to "quickly" do it is to go in and individually delete each unwanted page. Otherwise, it does most of what I want.

For doing signatures electronically this is fantastic! As a transplant patient, it's not a good idea to leave the house during this corona virus time, so this work as a great method to get this done.

What do you dislike?
The process to delete a page within document has changed and I feel as if it takes longer.
What problems are you solving with the product? What benefits have you realized?

What do you like best?
We use PDFfiller primarily for tracking and completing registration forms for the advanced trainings we provide to mental health professionals across the country. Manually managing these forms was a nightmare as our business started to grow. Once we started using PDFfiller, it began incredibly easy and hassle free to monitor who was registered for which trainings and when. the integrated PayPal and Stripe systems make it super easy to allow customers to pay registration fees immediately and we are notified as soon as that happens. Also, PDFfiller offers a digital fax line. In today's day and age, we are completely wireless and adding a hardwired fax line would have been such a pain. For 10 bucks we are able to digitally send and receive faxes which is very helpful when dealing with physicians and other medical providers.
What do you dislike?
We have only had one real issue with PDFfiller. At some point a few months ago, we had some issues with the PayPal/Stripe payment integration. We were unable to send receipts to our customer which was rather frustrating for us and them because of the amount of money people spend to some to our trainings. I reached out to someone at PDFfiller and a manager responded the next business day and said they would get in touch with the team who handles that part to get it fixed. Though I did not hear back, within a week or so the problem was fixed.
Recommendations to others considering the product:
Do it. It is well worth the price for what you are getting.
What problems are you solving with the product? What benefits have you realized?
Sending and receiving faxes through this program is a lifesaver. I am able to access them anywhere at any time whether I am in the office or out of town. It's also a great organizational tool for tracking out "link to fill" forms.

Best and complete tool to edit PDF documents. Editing PDF files is so simple and easy with PDF Filler like using a Doc editor. I use it everytime to edit dates and sign documents, just sign on my device with my finger so every signature is different. They could add a tool to increase the quality or resolution of scanned PDF files.
