What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Would like it if curser could "snap" to alignment, both vertical and horizontal, and then being able to maybe 'nudge' characters after typing using arrow keys. The red dashed line is very helpful, but getting things looking perfectly aligned takes careful precision with the mouse.

I would recommend, with caveats about the cost based on how much it would be used. Many government forms and other PDFs are already fillable, so PDFfiller isn't needed that often for the average person. However, it was very nice to use.

It is a time saving tool. There are times that I am faced with having to annotate, update or have a document signed immidiately I turn to PDF Filler with confidence...

What do you like best?
PDFfiller is a good cloud-based solution for signing and editing pdf documents without the need for a complete pdf editing suite. Uploading files is very simple. We just select Upload to go to the folder and then we can choose which documents to upload.
What do you dislike?
The speed of returning to the dashboard can be a bit slow sometimes. There is no autosave, so every time you log in on another session, you will exit from the first session and lose your unsaved work.
Recommendations to others considering the product:
I have recommended this service to co-workers and others in my field. These people work with many forms and applications and they can solve many problems related to online documents with PDFfiller.
What problems are you solving with the product? What benefits have you realized?
We can easily add the fields we need to any document. In just a few steps, we can send the document to the recipient to collect information or sign. It is especially useful when I leave my desk and need to sign a document on my phone.

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.
SSL Certificate Pinning, or pinning for short, is the process of associating a host with its certificate or public key. Once you know a host's certificate or public key, you pin it to that host. In other words, you configure the app to reject all but one or a few predefined certificates or public keys.
Pinning is an optional mechanism that can be used to improve the security of a service or site that relies on SSL Certificates. Pinning allows you to specify a cryptographic identity that should be accepted by users visiting your site.
Certificate pinning is the process of associating a host with their expected X. 509 certificate or public key. Once a certificate or public key is known or seen for a host, the certificate or public key is associated or 'pinned' to the host.
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.
