PDF editor

Question here.  I'm doing some web design and I have to create a training page for new employees.  This involves a presentation I've created and then a test afterwards however I have to have a printable certificate that I can produce after the trainee passes the test.  I’ve found an acceptable format but it’s a PDF and every PDF editor I’ve found won’t let me save any changes I’ve made because it is copyright protected.  Does anyone know of an editor that is free that will not pose this problem or even better a certificate that is already in HTLM format?

Thanks.

No, PDF is an open-standard.
PDF is a propietary standard Adobe can change anytime.

But PDF is an open-standard, Office formats are not.
PDF is a propietary standard, just like Office. The differences are that, in favour of PDF, it's more public, and in favour of Office formats, they are not completely useless, dead data formats, so I prefer the later, although naturally I prefer truly open standards to that.

For most things, I wholeheartedly agree.
