What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Experience was OK. Site is not clear on how to change type size and document size when filling in form. Also don't appreciate having to use PDFfiler and pay for a subscription just to save my document and print a copy. It contradicts your advertising for a Free service.

Great extension. Only been using for a day. Only thing so far that I find fault with is that text entered on the android version of the app displays on a single line whereas on the Chromebook extension displays correctly

I have been having trouble finding forms, and then getting the fill-in fields to work. While I like the end product I'm frustrated that it is not more user friendly.

I like the program It is not too complicated. The monthly fee is a bit too high I am not certain that I will be able to keep it past the free trial period. $20 per month is way off the mark; unless you have lots of cash flow. Just seems like $6-$8 per month would be more in line with the value of the product.

The experience was good, glad to be able to complete a 'Regie du logement' lease online and to maintain our paperless way of working. The text box takes more time than I'd like to align.

Well! I got the 114.00 per yr it did not tell me that I had to have the 184.00a yr program! Made me upgrade to be able to use it. It's a good program if you use it everyday I'm a small business owner so I only use it when I need it,

What do you like best? This platform is so easy to use. I usually get very annoyed with pdf files as most of the other websites I have tried have been a complete pain to make the adjustments I need. PDF filler allowed me to easily add the information, download, and save with my personal E-signature with my toddler on my lap ! I am very happy that I found them and will continue to use them for all my conversion needs. What do you dislike? I haven't really found anything that I dislike just yet. The monthly subscription is a bit pricy if you won't be using it often enough so maybe they could have pricing for example 4 downloads monthly etc. Recommendations to others considering the product: I would recommend What problems are you solving with the product? What benefits have you realized? I have been able to fill out pdf forms to submit documents online. It saves the time of printing the pdf, filling it out and then scanning.

What do you like best? The best thing is simply how it works. So many forms that need to be filled out and they are sent in formats that don't allow that. pdfFiller fixes that problem. What do you dislike? I haven't really found anything that I dislike. It's a great software. What problems are you solving with the product? What benefits have you realized? I do private consulting for government contractors and we have to finalize a LOT of Non-Disclosure Agreements. pdfFiller makes that a snap. Also we have many forms that have to be executed and it would be so difficult without this program.

A student-friendly experience I used this for easy homework access since they were in PDF formats. There was a problem with my subscription and payment process. I am glad my concerns were addressed in a friendly and hassle-free manner. More power to your company.
