Quality
The quality comes down first
The JPEG quality is lowered until the file fits under 100 KB. For most photos that's enough, and the size in pixels stays the same.

Two steps, only as far as needed: a photo that already fits stays under the limit.
Size
Then the picture, if needed
A large phone photo can't reach 100 KB on quality alone, so it's scaled down step by step until it fits. Camera details and location are removed too.

Check the form's other rules
Many forms also ask for a size in pixels, such as 200 × 230, or a minimum size in KB. If yours does, resize the photo to those dimensions as well.
