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.

Great software, some things are not intuitive You can edit documents, replace text, add fillable fields, etc. Great for documents that are used often and just need a few details changed. "Replace text" can be difficult to use. Also the process of saving a document is kind of clunky.

PDF Filler has been a great tool for our business for a professional look with a great price. Professional Look for a cheap price. The software makes filling out government documents / applications and other PDF documents easy and efficient. PDF Filler provides and saves time when filling out applications / tax papers / and other business files. It creates a professional look and is quite easy to use. With common files also at hand it makes filling these out quick and easy. The mail tool was even used when we completed our taxes. PDF Filler printed the paper out and mailed it themselves without us ever having to go to the post office. There isn't too much. If I could say anything sometimes the website moves a little bit slower than some. However this seems to have been improving lately.
