So you want to modify the text of a PDF by hand
Great post. I've spend a lot of time reading through the PDF specification over the last ~5 years while building DocSpring [1], and I still feel like I've barely scratched the surface. qpdf is a great tool. One of my other favorites is RUPS [2], which really lets you dig into the structure of a PDF.

Any decent free online tool which can give me a breakdown of pdf contents including relative sizes of assets such as images, fonts, etc?
It's not an online tool, but it's free nonetheless: https://github.com/itext/i7j-rups

I wish you good luck, this file format has tripped up many, many a developer. It blew up on a pdf I had lying around:
