Ripping 2D assets from Steam games?

Hello! I'm a new user, but I registered mainly to ask this question since I haven't been able to find much info on the topic. I'm not too tech savvy either to figure the answer out myself.

So would it be possible to use an external program to rip 2D sprites from Steam Games? The files are saved to your computer, so it feels like it should be? But again, I'm not exactly tech savvy...

If you can offer any advice, I'd really appreciate it. Thank you in advance!
