What free software to use in the company?

Question

PDF

I installed several free programs on my work computer, such as FoxitReader (PDF viewer), FastStone ImageViewer (viewing and editing images, convenient screenshots). But now they are forcing all this to be removed, because this software is paid for commercial use. Question: what are the analogues that are free for commercial use? (Don't even offer Adobe PDF Reader, after Foxit I don't even want to look at this guano). And in general, maybe somewhere there is a catalog of free programs for commercial use?

Answer 2

Once asked to demolish - ask to buy this software. And then apparently your employer ate a little. Doesn't give you a job

Answer 3

For taking and editing screenshots - Greenshot (GNU GPL license), for image editing - Krita (also GNU GPL).
