Oh I forgot to mention that tools like Illustrator and Inkscape are better tools for stuff that needs to be scaled into various sizes (like logos).
If you want a more in depth explanation, Photoshop and Gimp specializes in rasterised images (images made of pixels) whereas Illustrator and Inkscape specializes in vector images (images made of graphs). When you scale up or down a rasterized image, the detail changes along with it because you see bigger or smaller pixels. When you do the same with a vector image, the math stays the same; the quality stays sharp as a result.
Disclaimer: I’m no expert in this field and am only providing this explanation from my personal experience.
