You are on the right track with googling it, but it is still not easy. Google will help you always, but you need to suffer for it a little bit. It took me time to find what I needed. I looked, and looked, and I found a cool tool online where you can convert your files to PDF and edit them afterwards. That has helped me, they have cool templates that can help people who are trying to fill some immigration forms, and stuff like that. You will be able to find what you need on that website, I am sure.
