Add PDF files?
Like adding images, or videos, why not add a PDF file?

The problem for me was that I used to edit my PDF files with Word because I didn't know better. I hated signing PDF files because it would take too long, and it would never look good. My file would get all messed up in the end, and it never worked as I wanted it to work...
A friend told me about https://pdfliner.com/sign_pdf_online, a website that lets you sign PDF files, and it makes it easy to do. I love that website because it enables you to choose any signature design you'd like, and it takes only a few minutes to sign your PDF file. It saved me a lot of time since I started using it.
if this will allow me sign pdf files, then ok
