This has been very helpful. My only problem is a tried to sign up for a monthly membership and I ended up getting charged and receiving a year membership. That part is a bit confusing.

This program is a wonderful tool for those in need of completing documents with step by step instructions & returning later if need be. I appreciate those who assist with making this free program. It is a real Blessing also to those such as myself who cannot afford an attorney with knowing that forms are up to date & accurate. Thank you

What do you like best?
I love that this is a user friendly and cost efficient alternative to PDF editing. I have found that it can do everything (and more) than other services can. It is easy to use and excellent solution for our company
What do you dislike?
The SINGLE thing that I am not a fan of is the fact that encrypted pdfs can be sent but NOT returned encrypted. Sometimes I will send a form to an employee and need the PDF to be encrypted returned back to me and there is no option for that.
What problems are you solving with the product? What benefits have you realized?
The encrypted services have been a burden but the benefits are abundant. It is a great tool and I love that I can send our employees forms to fill out and they can receive/return them from their phones.

What do you like best?
I really like that PDFfiller is a very user friendly and employs a lot of the same standard editing tools commonly found in simple office software like Microsoft Word. It's a great step up from the standard Acrobat Reader and also has an easier learning curve than some of the more advanced Adobe PDF products. Being able to sign documents electronically is another strong feature.
What do you dislike?
When I edit a document that has more than one page, I am unable to perform a copy and paste across multiple pages, which is a bit annoying when trying to standardize items across one document. Saving documents is also very easy. We can save the document to any one of my computer folders or a cloud storage account.
Recommendations to others considering the product:
I think that PDFfiller is a very effective and easy-to-use PDF editor and converter. For the price and functionality, it's definitely worth checking out, in my opinion.
What problems are you solving with the product? What benefits have you realized?
Since we often deal with many types of text documents, especially Word documents, PDFfiller has really helped to enable conversions of Word documents to PDF, which are more ideal for certain things like printing. We can also convert PDF files to Word, which greatly reduces our need to perform time-consuming typing. In general, PDFfiller has been a great tool for working with PDF files with its intuitive interface and clear functionality.

A tool to get by, but far from perfect If you can't find any other tools to fill in PDF, or if you don't want to research into other advanced tools, this is OK. It can get your work done, but you will sometimes be frustrated. With this tool, I can fill in PDF which are not fillable by default. It saves me the trouble printing it out, filling it by hand and scanning it. It's easy to use and very straightforward. It's costly, taking into account of what it can offer. Sometimes it's difficult to save the file, and I have to save as another file even if I write only a few words.

Easy to use. Easy to use. I struggled a bit lining up fields with each other, but I guess there is an easier way of doing that than I am doing. For a first timer, I was happy with the experience.

Actual Customer Support I sent a question in via their form, and honestly expected a "word search" systemic response. Not only did I get a issue-specific response, the corrective actions were clear and documented with screen shots, making it easy for me to correct my mistake and move forward.

Very helpful website that is also… Very helpful website that is also realistic in allowing its customers a reasonable free trial. Very efficient and well thought through.

Fill out, sign, and send in no time Overall PDFFiller is a necessity for all organizations that have to sign and send documents in a daily basis. It is definitely worth it every penny. The thing I like the most about this software is how easy it makes it for us to fill out forms, sign them and send them to other recipients. In my job, I have to be constantly filling out employment verifications and with this software, makes it extremely simple. The price at the beginning was a bit high for us but all the functionalities make the price worth because of all the actions it helps me to do in seconds rather to find it different software to complete the same task.
