Definitely Useful As I mentioned, it makes the mailing process much more efficient. PDFiller allows you to create and mail PDFs easily, saving you the hassle of getting an envelope, purchasing a stamp, maybe having to go to the post office, etc. For me that has been its greatest strength. The PDF customization interface isn't bad, but it's not immediately usable. It takes a little bit of time to learn how to use it effectively. Right off the bat: I would not recommend this software to someone who isn't tech savvy or doesn't want a bit of a learning curve, for example, employers I've had in their 50s, 60s, and 70s who don't really "get" technology. The interface is fine if you just want to sign a document, but is not particularly intuitive when it comes to doing simple things like outright deleting portions of text. Too many steps.

Stress free I am able to get many projects done quicker and more efficiently with the use of PDFfiller. I enjoy the benefit of multiple different ways to finalize the project, send for signatures, print, email, save, etc. I love that this software is simple to use and I don't feel I need training to use it. Almost all the functions this software has is what I need to complete task in my professional role. I wish there were ways to combine documents, or if there is, making it easier to do so.

Good Quality My experience with PDFfiller is old, when I still needed to install the software. Nowadays I don't use it anymore, but in my college days it was very useful. The conversion of documents on the PDFfiller website is quite simple and does not change the structure of the actual document, which can be up to 150 pages. For most files, this is a good size. I find PDFfiller useful only for those who work with many documents to pay a monthly fee that is not high, but it is still something to consider.
