I completed a passport application. The document was easy to fill & very professional in quality which made it very easy to be understood during processing.
Michael R
Although I initially had thought this was free, the overall experience is a positive one. The insertion process could be initially a little more self-setting / precise but overall good to use for my purposes
John Haley J
Pros: +Has a send to sign feature +Allows editing of PDF text +Add/Remove/Edit Fillable fields +Save forms as templates +Up to 5 users with the largest subscription Cons: -Layout is not intuitive and hard to learn, even for the computer literate -Limits merging to 5 PDFs -Limits on file size (you can't work on large PDFs) -Other minor inconveniences that slow workflow I chose PDFfiller for my small company because for the same price as one user for Adobe's similar product, I can have 5 users for PDFfiller. It definitely has some limiting factors and can be frustrating but it's the best you can get for the price. Definitely worth the time to take the free trial and see how you like it.
Devin
Good service. Can be a little difficult to line up the text in the correct spot. Would be good if you could easily move the text box up and down a little to line things up.
Buddy C
Very helpful tool, was able to do all that I needed using it. Rate 5/5, recommend to everyone who needs to edit/sign PDF files and quickly share them.

Adobe for Life Overall, it's an amazing feature of the Adobe family that comes in handy for myself and especially in my industry where contracts are signed and requested frequently. So you're working on a project, job, whatever and you get a form that needs to be filled out, signed, and returned. It's a PDF file which is great because nothing can be edited off the original form. You're only responsibility is to fill it out and send it back, but you don't have a printer available, there's no fax machine around, and this form needs to be completed ASAP. The PDF filler is an amazing tool that gets the job done. Not only does it allow you to fill in information on any PDF file, it also allows you to upload your signature to docs as well. So while you can add your information to any pdf file, some of the files don't always allow for ease of filling out. For example, some forms allow you to type into blank spaces where words and information are supposed to go, while others have distortion issues and don't always allow for certain spaces to be typed into.
