Performance is slow and choppy at times. There is no OBVIOUS way to turn off the popups every single time I go to fill out a form. Transitioning from one form to another is extremely disjointed. There is no clear way to fill out one form and simply move on to the next in a series. If there is a clean workflow in there somewhere, it's not obvious, at least, not for my use case, which is to fill out a form for each of my employees from a remote location, download all and print all for distribution. Seems like every time I finish something, it takes a while to save, and a while to get to the page letting me choose what to do next, which is always to display the file list again, and a while to load the file list. . .rather than simply keeping the filelist persistent and hidden, as would seem same here. Also, this form, won't let me enter more than a character or 2 before kicking me out. I am writing this feedback in a notepad and then copying it in all at once. Awesome.

The program requires no OCR software which in my experience creates lots of problems for most "Form Filler" software I have tried to use in the past.

I use the website to do my W-2s and it was so easy. Then When I forgot to canceled my subscription because I am to small of a company to use them all the time they were so helpful and easy to work with. They gave me a full refund. There customer service is great and it is an such an easy platform to get things done with.

Excellent product never had an issue so can't tell you what support is like. Upload, fill and print
Quick and easy to work with. Have used other pdf products and this is best for the price.
Easy of use and no software to download. Cloud storage is great my documents are all stored where I know they are for future modifications.
Worry about encryption and security of stored documents but most of my work is not confidential so that is one reason I use it.

Firstly, I needed the form and capability to draft a residential Offer to Purchase. I've always just written offers by hand; needless to say it never looks as neat as a typed document. This did meet my needs.

What is a secure watermark?
When Watermarking is applied to a secure file, recipients will only have access in the Secure Reader and will see their email address watermarked across the document. The addition of the watermark is visible, but transparent enough to not obscure the contents of the file when viewed.
How do I add a watermark to a PDF for free?
Step 1: Select your PDF document.
Step 2: Add Text Watermark. Click the Add Text button at the top of the PDF page.
Step 3: Change text size, rotation and location on page.
Step 4: Change text color, transparency and font family.
How do I protect a watermark in PDF?
Go the View or Print Watermarks Tab depending on whether you want a PDF watermark when printing, viewing, or displayed on both.
From the Text Watermark tab add the text watermark that you would like to be displayed.
