Just learned this... So will copied as is from the source ( here ) I just learned something remarkable, and I have to write it down so I don't forget: Often IEEE conferences will require you to submit a PDF with embedded fonts. If you're forced to do this, no doubt you're familiar with a hugely irritating fact about most LaTeX packages: they don't embed fonts by default. There are workarounds, like the ps2pdf command line parameters that force font embedding, but using them can be awkward (e.g., if your LaTeX target isn't postscript, or if you're using a GUI LaTeX editor). But if you're a Mac user, like me, here's all you have to do: Open the PDF in Preview, and then save it again. It's saved with fonts embedded. That's it, seriously! Awesome, right?
