What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I found it relatively easy to use, it would be nice if it had an undo selection. And getting the right size font was not easy. Had to wait for print out to see.

The interface has improved, but it is not perfect. I chose PDFiller because of its simplicity. I love that I can use it anywhere without having to install it in every computer I use. I wish it included a crop feature or the ability to modify the page size. I also wish we could delete previous files with the same name so that there is no confusion. There are several other little things, but these are the top major issues I've had.

I would like it better if you just advertised "A Great Price" instead of advertising a "free" service. I would like to look at the tutorials before watching a webinar to get more familiar first.

What do you like best?
I like that I can fill in forms for all of my taxes, and they are saved permanently for future reference.
What do you dislike?
It is difficult to find a form that I need. I have to do a general google search, then click on the link, and fill in the form, then log into my pdf filler account. Wish it were easier to find specific forms.
Recommendations to others considering the product:
It's an excellent product for filling in forms, and creating documents.
What problems are you solving with the product? What benefits have you realized?
taxes. It has been helpful for me for the quarter and yearly tax forms I need to fill out (941, 940, W2's, W3's and 1099's).

It is my alternative for quick editing of pdf documents
I edit PDF documents quickly
It's software is quite intuitive. It is easy to handle. To fill out forms is great. Also to add the signatures to the documents
Once I wrote to technical support and I'm still waiting for an answer. It's the only negative I can say. In the end I solved the problem I had in another way

Since a recent update
Since a recent update, we were no longer able to send documents to SignNow for esignatures. The chat support was able to make some updates and get us working again.

I love this software and use it frequently.
Has a free trial, has many tools, easy to use and has template searching capabilities.
If you have the basic plan, customer support could take 24 hours to get to you. If you have the premium plan, customer support answers immediately.

How do I verify a certificate pinning?
You can check what's on your own device by going to Settings > Security > Trusted Credentials. There is an assumption that none of these root CA's or the 1000s of intermediate CA's these root certificates trust will mis-issue leaf certificates for domain names they shouldn't.

What does pinning a certificate mean?
Certificate pinning is the process of associating a host with their expected X. 509 certificate or public key. The former adding at development time is preferred since preloading the certificate or public key out of band usually means the attacker cannot taint the pin.
What is certificate and public key pinning in mobile application development?
Certificate pinning is hard coding or storing the information for digital certificates/public keys in a mobile application. Since the predefined certificates are used for secure communication, all others will fail, even if the user trusted other certificates.
How does SSL pinning work?
SSL pinning allows the application to only trust the valid or pre-defined certificate or Public Key. The application developer uses SSL pinning technique as an additional security layer for application traffic. As normally, application trusts custom certificate and allows application to intercept the traffic.
How do I verify a certificate?
To verify a certificate, a browser will obtain a sequence of certificates, each one having signed the next certificate in the sequence, connecting the signing CA's root to the server's certificate. This sequence of certificates is called a certification path.
How do I check if my certificate is valid?
Click the Three Dots. You will find them in the top right corner of your browser toolbar.
Select Developer Tools. Scroll down to More Tools and then click on Developer Tools.
Click the Security Tab, Select View Certificate
Check the Expiration Data.
How do I check a certificate format?
If the certificate is in text format, then it is in PEM format.
You can read the contents of a PEM certificate (cert.CRT) using the 'OpenSSL' command on Linux or Windows as follows:
OpenSSL x509 -in cert.CRT -text.
If the file content is binary, the certificate could be either HER or pkcs12/PFC.
