What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
This is a pretty good tool to use for filling out, signing, sending, and working on high school scholarships! you can open .pdf files right on the program and fill them out and even sign them and email them to the recipient. The only downside is the cost, its kind of ridiculous in price.

My very small office (staff of 9)!needed a professional looking and very easy to use application for filling and signing document. I downloaded 8'different apps/programs for trial and comparison. PDF Filler left every other program / app in its' dust.

It was very easy to Fill out the PDF. Then I was suprised I could also mail it, from the same website. I can upload a PDF and have it mailed, even by Certified Mail. That you can mail or fax the PDF. You can like email to fax. Which is very good. Especially since I don't have a phone anymore, let alone a fax, since I just use my Cell Phone. Technical support is terrific. They are always availble, they know everything, they are very helpful. For example, one technician let me email him my PDF, he fixed it for me, and emailed back to me.

Slick tool. Nice editing capabilities. Some of the menus are confusing - for example: finding where to update an existing link to fill document is challenging.

What do you like best?
I like how intuitive PDFfiller works compared to using a typical graphic design application to fill out PDF forms. PDFfiller does a good job at understanding how to format common documents and makes it easy for me to download files after filling them out. I think that the pricing for PDFfiller is very reasonable and the website is designed very professionally.
What do you dislike?
I have been able to use PDFfiller very smoothly in the time that I've used it, but it's not always perfect when it comes to formatting certain documents. I think they are improving all the time though.
Recommendations to others considering the product:
I would recommend PDFfiller for filling out digital documents, for sure. I think if you compare it to other cloud-based software tools, you'll see that it can work more smoothly with your workflow in many cases.
What problems are you solving with the product? What benefits have you realized?
We work with lots of digital documents, and since it can take a long time to fill them out through printing, writing and scanning, PDFfiller really helps to streamline the document filling and signing process. Everyone on our team that uses PDFfiller was able to start using it without problems pretty quickly.

I just started using it today I just started using it today. So far, I am very happy with it. I was able to use the draw feature to sign where I needed to, how I wanted to without using the "sign" feature.
