As a freelancer I use PDF Filler to complete W9 forms - it's great! PDF Filler is simple, easy to use, and creates professional documents that are easily accepted by employers and large corporations. The exporting workflow is a little confusing - at least for their IRS W9 Form. Instead of just pressing a button to save the file to my phone I had to email it to myself in order to obtain it. This may have just been my ignorance, however. All in all, PDF Filler is a great help!

Simple tool that increases productivity in office I'm a software engineer and have to deal with many documents everyday. Having a simple tool that has all the features needed for me to edit and handle all my documents makes my life easier. At the same time it saves me time to look up new tools and ways everyday. The UI is simple and intuitive, and it's easy to attach files, download and share it as needed. Overall it makes me more productive in office. My favourite feature is the electronic/digital signature feature. As a person in the IT department, I have to work with numerous documents and sign many of them. And this tool made that really easy for me. Also, the signature looks blended out and not out of place. Other than that the merging tool and conversion tool are also very helpful. Depending on my needs, sometimes I can convert a ppt into a pdf for easy access or for sending it to anyone. I also get to attach different pdfs together in whatever order needed. I don't have any major concerns. The only small problem I've had is regarding character recognition from scanned pdfs. Sometimes it is not entirely accurate. Though it is manageable for me.
