I'm a little bit new at the process, but I'm interested in learning as much as possible about any new technologies, that will save me a little bit of time.

Easy to use. After great frustration with other apps to fill in pdf forms, pdfFiller has been the easiest and most efficient method for me to complete forms.

A feature that is critical to my business broke on Friday. I was able to interface and get updates about the fix over the entire weekend and had the problem solved by the dev team before Monday morning. Awesome teamwork from the folks at PDFiller from end to end. Highly recommend.

Good. I used to use Docusign but they ruined everything by not allowing direct access to an existing account within email. It would be good if you could do that btw - when you preview a document in gmail you should be in the dropdown list of options for opening the doc and editing it.

Great PDF Filler!
We needed and easy way to for patients to sign there name for Covid testing. Before we came across this they were signing with pen and paper and now they sign digitally on and case protected iPad that can be wiped down and sterilized. The iOS pdffiller app then digitally sends the completed PDF to a nurse. The whole process is seamless.
PDFfiller is very easy to use. Some features that we love are:
-Being able to convert a file into a PDF
-Converting a PDF into a Fillable PDF
-Creating PDF online.
There is also a mobile application for Android and iOS that works great.
Initially it was tough finding out where things were and where the files ended up when saved or converted over to be fillable. I think the menu could be simplified and reorganized.

pdfFiller has helped me so much with…
pdfFiller has helped me so much with working from home. Switching technology, updating documents and signing forms was not always smooth, but this pdfFiller kept work going.

Very easy to use, being an assistant and constantly filling out reports for the State, it is nice to have something that works so easily and is consistent in its responses.

What do you like best?
User friendly. Can do anything I really need, from editing pdfs, splitting up and saving parts of documents, signed documents, etc.
What do you dislike?
The sign in page can be a bit wonky and hard to see if you're signed in. If you've been signed out and start uploading it puts you into the trial mode, and once you figure out whats going on you have to start over.
What problems are you solving with the product? What benefits have you realized?
Signing documents is really important for me, which is the biggest benefit. But the ability to edit and fill out pdf documents has been wonderful as well.
