Can't upload a profile pic please help?

What am I doing wrong ?
Keeps saying photo has to be less than 500k but don't know how to get my pic this size .

You might need to take a photo using a smaller amount of megapixels? Or try editing it? Sorry I'm not much help on technical things. 😊

Just do a Google search for photo resizers? It's easy enough to do👍🏼
