King of PDF Filling PDFfiller really saves time by allowing you to directly write on the PDF. Previously I had to print it out and fill out the details and have to rescan the document and PDFfiller eliminates all these steps. It's very simple to use as you just have to drop the PDF file which needs to be filled. The biggest advantage is that it also works with a file which is not "fillable" by allowing you to add text and images on it. Often times larger PDF file doesn't work directly so I have to divide it and have to re-upload them again. I think it would be really helpful if PDFfiller allows such functionality by default where it either works directly or ability to divide it on their website.

Easy and time saving I use it to fill out government and medical forms for personal reasons. It could be used for any form you might need to complete. It's very easy to use and has tons of forms available. You can upload unique forms and it works great on those too. I have had some issues finding forms I've completed.
