Is there a way or program i can use to resize an image while maintaing the same quality?

Question

I want to make a background for my desktop but everytime i stretch it...the quality is very bad.

Answer 1

No matter which program you use, if the size is low to begin with, it will always be blurred when you enlarge it!

Answer 2

ya but you'd need photoshop =/

but you can try using paint, and press ctrl+w.  and increase the precantages, dont drag and resize it manually.
