What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Exactly what I was needing for my real estate business to take it mobile. Nothing else is exactly like it - none of the "signing" apps quite cut it. Thanks, PDF Filler!
2014-05-05
This is a very good program but the monthly fee is high. It would be well worth the cost if you were filling out hundreds of pdfs each month, but for one or two forms, it's hard to justify the expense.

Top notch support team!
I want to start by saying that this program exceeded my expectations! It not only delivers on everything it promises but goes above and beyond. I used it for a marketing class, and it made the entire process seamless and straightforward. When I encountered a billing issue, the support team resolved it promptly—even during a holiday weekend! While the PDF filler functionality is outstanding, I’m even more impressed with the exceptional customer support. Thank you very much for the excellent service!

Can you remember what all the lower…
Can you remember what all the lower case letters look like when you are filling out forms by hand. I didn't remember, but when you use PDF filler you it does it for you.

So far so good..
So far so good. Actually of every editable pdf or doc app out there, this one has by far so many options you can choose from to suit your editing needs

So far, so good
So far, so good. Does as it claims to.Some of the functions e.g. merge could have more accessible controls (you have to gone into a few menus), but when found they do their job well.Maximum document size is 25Mb so if you have a bigger document you have to use another online splitter and go from there. Don't really see why that functionality could be integrated though.

It did the work as I wanted it to…
It did the work as I wanted it to provide me. I will still use it for more tasks and hopefully it stands to its reputation, functionality, and super-low to free trial time length because I am still just a student.

Signer Authentication and Security. Two-Factor Authentication
Has anyone attempted to steal your online information lately? We understand that while many of you like the convenience of logging in to your online accounts with a single click, others are more interested in enhanced security options. In order to help prevent phishing for your login credentials, pdfFiller is one of the first document management services to develop an account login with two-factor authentication.
If you go to our login page, you’ll notice that there are now four different login options available. The first is the traditional email and password combination. Remember that if you click on the checkbox next to ‘Remember Me’ and close pdfFiller without logging out, the next time you open pdfFiller, you will be taken directly into your Medics page. There is also an option to retrieve your password here using an email or phone number. For those of you for whom security is a priority, pdfFiller also allows you to log in with your phone number. This recently added option, available to those who have a phone number saved in their account information, requires a two-factor authentication process, similar to what you may have encountered when dealing with your online bank accounts. Simply click the ‘Login with Your Phone’ button, and you’ll be taken to a page where you can enter a phone number. After clicking ‘Send Pin’ you’ll receive a code via SMS. Enter this code and click ‘Log in’ and you’ll be taken directly to your Medics page. This method, which requires two keys for account entry, helps prevent phishing and makes it much more difficult for a stranger to access your personal information.

08

Did you know?
New in version 1.8: Support for login form authentication was added to make:auth in MakerBundle. Make:auth generates a login/logout route, a login form template and a Guard authenticator. The Guard authentication system is powerful, and you can customize your authenticator class to do whatever you need.
Authentication technology provides access control for systems by checking to see if a user's credentials match the credentials in a database of authorized users or in a data authentication server. Users are usually identified with a user ID, and authentication is accomplished when the user provides a credential, for example a password, that matches with that user ID. Organizations use authentication to validate users who log into their websites.
At one time, 86% of more than 2 million breached passwords were identical to passwords that had already been breached. The solution to security on your entire computer system or on your smartphone is a form of secondary authentication. Biometrics is a term that refers to measuring unique individual characteristics such as the retina, the iris, fingerprints or even the face. Multi-Factor Authentication MFA allows you to use passwords for a longer length of time between password resets.
