10KB is mostly about dimensions

At 10KB there are very few bytes to work with, so compression alone cannot save a large image. The reliable approach is to shrink the dimensions first. A signature cropped tight and resized to a few hundred pixels wide compresses to 10KB cleanly; a full photo does not.

If a form demands 10KB, ask what it is for. Signatures and simple ID thumbnails fit fine. For a real photograph, 10KB will always look rough, so confirm the form does not actually allow a more reasonable size like 20KB or 50KB.
