I am a novice for graphic design.
I have a low quality image which is given by my friend, its size is really small, but we want to make it bigger and clearer so that we can use it as a banner or logo or etc.
So my question is what is the easiest way to get a better quality image from a given(smaller, low quality) image?
Should I manually draw it, and how, what tools to use?
Or is there a way which I can easily convert it to a vector and then increase the size and then save it back as a png?
