Great product.
Good interface gives you all the options you need in one place. Clear and easy to understand. The only downside is remembering its a browser only interface, remembering the product name and having to navigate to the URL to begin. Not an issue for a daily user, but if you use only intermittently like I do, I have to make myself a reminder. To that end, I think its a little expensive for a casual user; but I do still like the interface so much that it overrides my concern on cost.

3 times I have contacted PDFFiller support and every time they have responded in less than 30 minutes. This is the fastest support service I have ever encountered.

I really like the program; however, when I save I get logged out. I have not been successful at using any form except the Offer to Purchase. I need addendums.

easiest way to fill forms!
I like it and I recommend it to anyone who works with Forms that cannot be edited using another softwares.
In my job we need to complete a LOT of forms (we are a law firm specialized in tax and corporate law so we need to complete a lot of forms that come in PDF format) and some of them doesn´t allow us to make any edit in the regular PDF program so PDFFiller is our salvation. It is super easy to use and it allows you to edit the entire document using only this software. You can add text or even delete parts that you don´t need. It is a software that doesn´t require any effort to understand because everything is as simple as upload the document, make the changes and save as pdf or print the document. I use it every day and I find it very complete for the things that I need.
You are not able to use it in several computers, so if by mistake you open your session on another computer you may loose your work.

Kara was spectacular
Kara was spectacular! I was having trouble merging 35 small PDFs into a single larger document. She walked me through all the steps, and I told her what I had done and where I had run into problems. When she could not find a solution for me that way, she offered to merge all the documents for me!!! I have been working on this family project for the last 12 months and this was the final step before I could get the finished document out to everyone. Now I can do that and put this phase of the project behind me! I salute you Kara!!!

The application software is a great tool. But, when I search for another fillable document of the same, it does not allow me to pull up a clean form fillable document, for example local tax forms. Thank you.

How do I change the highlight size on a PDF?
Select the “Highlight Area” tool and apply the desired highlighted area on the PDF document. Once the highlight is applied, right-click on the highlighted area. Select “Properties”. In the “Display” tab, select the desired color for the highlight area using the “Fill Color” option.
How do you change the highlight on a PDF?
Open any PDF document, go to menu View → Comment → Annotations, right-click on the “Highlight text” tool, choose “Tool Default Properties” and you will be able to change its default color.
How do I highlight an area in PDF?
Highlight your PDF Left-click the mouse, hold it, and move around the page to highlight the area or text. Release the mouse button once the area or text is selected. Once the PDF is highlighted, you have the option of adding a description to each annotation, which you can do from the left vertical panel.
Why can I highlight some PDFs and not others?
Most likely because the file is composed of images (possibly scans) and does not contain any “real” text. If you can't select the text with the text selection tool then you can't highlight it, either. Use other markup tools, like the Square tool, instead.
