What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
At first I was a little concerned. Difficult experience in the past. More business are utilizing e-sign, Do c-section and Right signature. Nice that I can utilize this program with compatible other programs

I feel this is just what I've been looking for and it's not to complicated like some of the other sites and you still don't get what your looking for . I didn't get get what I wanted on other sites. That's why I purchased for a year because this works good with my busness.

It is very user friendly. I do not like that you have to use the eraser to delete text but otherwise it is way better than other programs I tried. I am also having problems opening pdf filler links on my business account because it goes to my personal account every time because it's on the same computer. I will call customer to fix the problem. Otherwise we are very happy with it!

What do you like best?
I can send as many documents out for signature as I want. No restrictions. I used to use Adobe, but they had a cap on the amount of documents you can send for signature. When I tried to get that upgraded, they had outlandish prices for this same service. With PDFfiller, I can send all the documents I want and I'm also able to save all of them securely.
What do you dislike?
I wish the PDF conversions didn't come out like pictures. When I convert a PDF to Word, it always comes into Word as a picture instead of being able to edit the document. As a recruiter, I receive a lot of resumes that need some work before we can submit them to clients. I still have to use Adobe for this function, so now I'm paying for two PDF programs. I can't just stay with Adobe though because of the above mentioned issues.
Recommendations to others considering the product:
If you need eSignatures, this is the program to go with.
What problems are you solving with the product? What benefits have you realized?
Remote onboarding is a breeze with PDFfiller. I am able to send HR documents to people across the country and still get them to work on time. I'm in VA and have to get employees to work in all states across the country, as well as oversees. We have to get documents to them for signature and faxing doesn't always work. With PDFfiller, we can send anyone any document and get it back fully signed by them. It's truly wonderful.

Awesome PDF Tool for a low price It is a great tool that I would recommend to people who are not very tech savvy. It is an easy to use tool with helpful features that can help any business that uses PDF documents on a frequent basis. It makes you pay for many features that can actually be found using free software alternatives if you do some research.

Recommendations to others considering the product: It is fully recommended, the results obtained have been very gratifying and satisfactory. You simplify a large part of the work that allows you to save time even you maintain a constant work flow. Share documents through email, social networks among others. In general it is very complete and a good option for all companies. What problems are you solving with the product? What benefits have you realized?
