How to make your avatar?

1
Hey guys I use my iphone/iPad to access this forum and I’m having a little difficulty shrinking a picture down for my avatar. Is there a website you guys use to shrink a photo down to size? I think it’s 15kb max for avatar.

I’m not the most tech savvy guy lol

Edit: not sure if this is where I should post this thread, move it if needed.
