User blog:ImARandonGamer/Little help please?

I made my first ever sprite a while ago and it was for my Cursed Orb idea. I had put it on the page, however it's gonna need to be resized. I had to use an application that has a small amount of space to work with and as a result the sprite is rather small. I would resize the sprite myself, the only problem is I have no idea how. The application I used is probably the only option I have because I use a kindle fire that is about 5 or 6 years old and it's a bit outdated on applications, music, etc. If someone is willing to help me out here it would be deeply appreciated, I would happily credit you for the help in the Credits section of the Cursed Orb page.
