What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
I was looking for this solution. I work from multiple locations and multiple computers and using other pdf softwares that only allowed me to use the software on a certain number of registered devices was not a good solution for me anymore. I would have given this 5 stars, but I am still learning to use it, and I wish it was faster. In all fairness, the the lags may have to do with the processor in the chromebook I am primarily using it on right now which may not be that fast. It was an inexpensive device so it is very possible that my device is the reason for the slow transitions and not the software.

Wish there was a way to make all fields NOT-required, and add the required feature to the one I want, rather than undoing. Also, wish there was a way for the app to add fields where they seem to belong.

Really great product. So many of the forms I am sent would mean hours of unnecessary handwriting. With PDF Filler I am able to complete them in 1/2 the time. (The only negative is the learning curve, but once I learned how to maneuver around its great!)

Customer service is A1! Wow! Customer service is A1!I needed to fill out some forms for an outfit, a one-time thing, and signed up for the trial month.Later in the month I tried to cancel the trial period before my credit card was charged the $20, but I forgot which email account I'd used to sign up, so I was unable to log in to my PDFfiller account.Today, when I received the email saying my credit card was charged the $20, I was able to contact PDFfiller since I now knew which account I'd used. I contacted them via "Contact Support" in their website and explained my situation. OMG! When it said I should receive an email in 20 minutes or less, I was thinking, "Yeah, right!" but it was literally only minutes before I received an email saying they would be glad to cancel the subscription and refund my money.If I ever need this type of service on a more regular basis, I will definitely be signing up with this company!

I really like the service a lot. It is user friendly and intuitive. I like that this also comes with Sign Now so that I can have all the forms I need for my business easy and accessible for me to get electronically signed. I would give it 5 starts except in the Sign Now program the program should default to the text box for people to sign and then have the live signature be on a separate tab, so basically reverse what it is now. It is hard for some people to get to the text box for them to type their signature. I use this all the time in my business and I would recommend it.

Mark optional fields, not required Most designers use asterisks to indicate the required fields. But it is necessary to stop, the research on the subject is clear, and it is already the case for quite some time, used asterisks for the required field is a common mistake.

”Field is required” is a flag that has absolutely nothing to do with screens. You either need to remove the flag in the field configuration, making it optional, or you need to add the field to the screen, so the user can obey the mandatory rule you've set.
Mandatory fields are questions that must be answered before the form can be submitted. Mandatory fields are also called compulsory or required fields. The opposite of a mandatory field is an optional field. Optional fields are also sometimes called voluntary fields.
The bold fields mean the column header is required. If you are not going to populate an optional field for all rows in a data import file, it is best to omit that optional field entirely from the file. School_id, for example, cannot be included and left blank for all rows.
Required fields, also known as mandatory fields, are questions that must be answered by the form-filler. The opposite of a mandatory field is an optional field. With these questions, form-fillers have a choice.
