Had a problem with being unable to save a document. However Sam on the chat line was very helpful (although we could not recover it) and suggested changing the input from javascript to 'flash'. I have now managed to save it.

such an amazing site!! I love PDFfiller.com!! it makes editing forms so simple and easy! I would have rated 5 stars but I have a difficult time using it on mobile devices.. other than that it is the #1 tool I go to when I have to edit or even FIND a document using the search tool! when I finish a document I can send via TEXT, eMail, Fax, WhatsApp and so many more!! or I can just print or save for later. Thank You So Much for this wonderful site! I recommend this to anyone and everyone!!

I appreciate the ease of downloading a PDF and being able to fill it in. For me, it is worth the money, even if I don't use it very often, simply because I now have the completed form saved, and easy to edit, as needed.

I think it has all the features that other pdf signing software offers and it's well priced! I use it on a regular basis for all my pdf signing needs.
What do you dislike?
I think user interface can be improved but so far I've gotten used to it so it's not so bad.

It really is a great tool, and well priced compared to the other competitors in the field

I've been able to sign and fill out pdfs faster than ever. I've been able to have my real estate contracts signed quickly and effortlessly from my clients.

What do you like best?
The ability to modify; merge; create; add signature to any document. This program saved my day. Without it my work would be impossible.
What do you dislike?
I wish that I could add more than one page at a time.
Recommendations to others considering the product:
I've found this a valuable tool to use in my daily tasks when I am handling a document that needs to be massaged. It's a lifesaver for me. Don't know how I'd complete tasks without.
What problems are you solving with the product? What benefits have you realized?
Tons of features, just what everyone needs to make a task easy to accomplish.

Excellent customer service and response… Excellent customer service and response time. Very easy to use platform. Tons of capabilities and resources built in. Legal forms lists and easy to use e-signatures!!! This program is amazing!!! I'm an owner operator of a small construction company and can't believe I've been in business for almost 10 years without these resources so far. My success is now at my finger tips and I'm able to create bullet proof contracts, forms, notices, and change orders with e-signatures at a drop of a dime!!! Thank you pdfFiller!!!!

What do you like best? I love the ability to create forms from both pdfs and word documents. But the link to fill feature is my favorite. It allows persons to complete a form by simply sharing a link. What do you dislike? The sign now feature needs to be better developed. I need the ability for one person to complete a form and then get it signed by others before being returned to me. What problems are you solving with the product? What benefits have you realized? We are able to cut down on printing cost, and have been able to reduce turnover time for gathering information.

Great customer experience with this company. Very responsive to technical questions and billing service cared more about our satisfaction than most companies even though it wasn't to their direct bottom line advantage. Will use them again surely.
