What do you like best?
I like that you can save the template for a certificate of insurance or an application and send it out that way. It still saves it as new but also creates the new Document.
What do you dislike?
The same feature that I love so much, isn’t quite as easy to navigate on the App. It’s super easy on the full online version though.
What problems are you solving with the product? What benefits have you realized?
Super easy to use on the go with the App access. I live that part of it.

I find that using your program is easy to navigate and looks professional when completed. I find that using your program is rather easy to navigate. The only issue that I have had is when I try to print a document, there have been quite a few times that it will download to 63% and then gets stuck there. I have to close the document and try again....sometimes several times until I can print it. Besides that, it has been great!

Perfect for College I've been using this for my online math course worksheets and this has been so helpful. It's easy to type and draw, editing isn't annoying, and the color palate is easy on the eyes.

Super helpful site and people Super helpful site and people! I had to contact them about a billing issue and they were immediately able to resolve it for me.

I have only used it once before and I like it. Some of the fill-in spaces are challenging, but I'm sure it is because I haven't mastered the software yet.

What do you like best? I like that you can edit files, sign without sending through electronic envelopes and you can fax and email documents. What do you dislike? You cannot upload separate files and merge them into 1 pdf file within the program. Recommendations to others considering the product: I highly recommend using this app for your document prep and signing. It is a one stop shop to get your pdf files edited and signed. What problems are you solving with the product? What benefits have you realized? The benefit is the faxing capability and being able to do it from my phone.

Why pdfFiller is a better alternative to your current PDF editor

The fundamental functionality of a genuine PDF editor is to create, edit, share and convert PDF files in a fast and efficient way. A PDF editor should effortlessly convert a variety of file types without damaging the original quality. Yet there are numerous platforms providing this functionality, most of them are limited or provide it as a paid feature.

For a daily use, you'll need a cloud-based solution that will guide you all the way up from document creation to its signing. Although PDF editing is a useful tool, it's just not enough to build an effective paper-free workflow.

pdfFiller is a browser-based fully-featured document editing tool which lets you produce, edit, sign and store PDF documents across all of your devices. It comes with a cloud storage to make backups of your templates accessible to you and your teammates, all the time.

Using pdfFiller, you can use just one browser page to:

01
Get a mobile application for iOS and Android
02
Go to the form library for over 25 million ready-to-use fillable documents
03
Create professional-looking documents on your own: business, tax, legal and much more
04
Use integrations with Google Drive, Dropbox and OneDrive
05
Distribute forms via QR codes or hyperlinks through email, SMS and/or social media

pdfFiller keeps things simple while at the same time providing you with essential editing features: highlighting, redlining, fillable fields, signing and more. We might be biased, but we know users choose pdfFiller for a great number of reasons.

Compliance

pdfFiller complies with PCI DSS the same level PayPal or Stripe do. In order to protect, securing and storing medical records, pdfFiller is 100% HIPAA-compliant.

Pricing
