Questions about Reduce Image to KB

Can any photo go under 20 KB?

Usually yes. If quality alone is not enough, the photo is also made smaller in pixels until it fits.

Will the photo still be clear?

Passport photos and signatures stay clear at 20–50 KB. Very large photos lose more detail at small limits.

Why is the result a JPG?

JPG gives the smallest files for photos, and most forms accept it.
