I've only done two documents, but so far I think it is a swell program! I have one more trustee that I'd like to add, will that cost more? We use the program for a charitable trust and we are unpaid. Thanks a lot, no matter what the answer is! I really like the program. MP

What do you like best?
I love the program as a homeless case manager, I can review information with clients, send to them for review, and signature from my office
What do you dislike?
It needs a desktop application for easier access vs going to the website all the time.
What problems are you solving with the product? What benefits have you realized?
decreasing my travel, having access to documents when I need them in the PDF website, and access to cloud networks

Good service but some things like… Good service but some things like filling out spaced letters are more difficult than they should be and paying for the service feels bad.Overall good though, being able to sign online is a nice convenience perk.

Great, this time so far. I used the program a little over a week ago but my documents were messed up because I was not told I had to pay first in order to save or print the document. I had to create it all again. It was the same one as this now, 821 ssa form. It took me hours to get as far as I had.

Great Experience and Efficient PDF's I only needed to use it for a few items I needed to update. The experience was easy and great. I enjoyed using it for what I needed in the moment. Once I cancelled my subscription they handled it promptly and professionally. If I am ever in need of PDF services again, I will definitely consider their services and so should you!!!

Discover pdfFiller as your new fully-featured PDF editor

The fundamental functionality of a good PDF editing platform is to create, edit, share and convert documents in a fast and professional manner. A PDF editing platform should be able to convert your documents into various file formats, so you can work with them in any other program. The majority of the tools are providing this functionality in one way or another, but limited or as a stand-alone product.

Although PDF editing is a useful feature, it's just not enough for a modern user. For a daily use, you'll need a cloud-based solution that will guide you all the way up from a document creation to its signing.

pdfFiller is a browser-based tool that grants you access to every feature you need for your PDFs from any device, whether desktop or mobile. Additionally, it’s cloud-based, so your documents are safely stored and can be easily accessed by you, your teammates, or anyone who has a permission, at the same time.

With pdfFiller, you can use just a single website to:

01
Edit PDF online with a mobile application for iOS or Android
02
Discover the library of over 25 million ready-made documents
03
Create professional-looking documents on your own: business, tax, legal and more
04
Export you templates to Google Drive, Dropbox, Office 365 and other common tools
05
Send forms to other people to fill and sign via email, app requests, SMS, QR codes or social media links

It guides your through the whole process, making it easy to highlight the document text, put in fillable fields, sign and much more. We might be biased, but we know users choose pdfFiller for many reasons.

Safety

Every document you interact with from your account is protected and copied to secured servers after each session. You are free to access it and check the records anytime. For an additional security, set up passwords for your files and a two-factor validation to your account.

For protecting, securing and storing medical data, pdfFiller is 100% HIPAA-compliant. pdfFiller complies with PCI DSS the same level PayPal or Stripe do.

Pricing

pdfFiller doesn't charge you for particular features, which makes it affordable. Compare it with other software-based tools to see just how much it differs for almost the same features.
