Initially, it was a bit confusing. However, after using the program a few times, I am delighted. I very much like the fact that I can take a printed form, scan it, and then fill it in and print it. The result is very professional looking. Still not sure how to change fonts.

I found that my typing was faster than the rate that the data shows up on the screen. I didn't like that. My attorney found this link for me, I was unaware that this was a system I would have to pay for. A customer service ticket was generated because I needed help.

Awesome!! I don't know what I have done without you. I do real estate transactions weekly and I love that I can upload different documents, edit them, and send them out. Well worth the cost. Thank you.

Easy to use, the functions are very intuitive Easy to complete documents online and share electronically instantly Pdf filler is very easy to set up and use. The monthly fee is at a low cost. Using this service makes completing and sharing electronic documents simple and efficient. It is not free but is a very good value. You can try it for free to see how the program works but if you chose to use it, you will pay a small fee before you can print or send a completed document. Some pdf files are not compatible or are difficult to get the text exactly where I want 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.

Chosen solution If you go to the Firefox settings page and scroll down to the Applications section, you should see the Portable Document Format (PDF) content type listed there. You can change the default action to Open in Firefox if you want Firefox to load the PDF instead of downloading it. Hope this helps.
PDF file handling options Go to Options > Applications, then find the listing for Portable Document Format (PDF). Under the Action column, you'll see that it's set for Preview in Firefox. Click the drop-down list to select an alternate PDF viewer.
