This program is awesome. Not only does it solve the problem of not being able to type on pdfs, you can also sign a form that is on your desktop computer on your phone. Amazing.

The interface has improved, but it is not perfect. I chose PDFiller because of its simplicity. I love that I can use it anywhere without having to install it in every computer I use. I wish it included a crop feature or the ability to modify the page size. I also wish we could delete previous files with the same name so that there is no confusion. There are several other little things, but these are the top major issues I've had.

It's pretty good. There is a delay from when I type till when the text appears in the text box.Also, I don't like have each field with a help box. I know I can X it out but it gets in the way when I want to go fast. I do like that it goes automatically from one field to the next such as with the dates.

Saves so much time I like this software because it is so easy to use. It saved me time and allowed me to quickly complete the necessary document The only con I have with this software was that when printed it did not print all of the words typed in

Great for .pdf that You Need to Edit-PDFfiller is the way to Go! Great for doing 1099s at tax time! Wonderful for use with prefab downloadable boilerplate documents that you purchase from the web. Great storage for being able to go back in and repurpose a saved document for an additional use. Print alignment not always spot on for forms, such as 1099s and you have to play with settings a bit, but overall not too cumbersome.

needed a PDF filler software easy to use easy to fill out lots of PDF forms without hassle Easy to use. Can save forms for future use. Does not require any extra learning. Intuitive format makes easy for anyone to use. Cost was a bit much, but decided the year membership was the best savings deal. Have used it multiple times already in the first few months so I am glad I did not do a month to month membership.

PDF filler is VERY easy to use PDF filler is VERY easy to use. The only sticky point for me sometimes is finding forms. There is a library connected to the app but I often find the forms there confusing. So I google them and import.

”Field is required” is a flag that has absolutely nothing to do with screens. You either need to remove the flag in the field configuration, making it optional, or you need to add the field to the screen, so the user can obey the mandatory rule you've set.
Mark optional fields, not required Most designers use asterisks to indicate the required fields. But it is necessary to stop, the research on the subject is clear, and it is already the case for quite some time, used asterisks for the required field is a common mistake.
The bold fields mean the column header is required. If you are not going to populate an optional field for all rows in a data import file, it is best to omit that optional field entirely from the file. School_id, for example, cannot be included and left blank for all rows.
