There are many tools that will convert images to vectors for free, but the success of this will be based on the logo you're trying to do it with. If it's something with hard/smooth lines, and flat colors, i'm sure they will work just fine. The Bernie logo in your avatar is a good example of an image that could be vectorized automatically with really good fidelity.
If it's a logo that has finer details or some photorealistic images, the vector results of these free tools may not turn out true to form. Making a vector in Photoshop, Illustrator, or even the free online tool Photopea is super simple. You just make a new layer over your logo and trace over it using the pen tool. Lots of quick guides online to help you through this process if you were looking to take a stab at it yourself. GL!
