Compress Image to 100KB: what to know before you start
Documents need more KB than faces
A face photo looks fine at 30 KB, but a certificate is full of fine text. If the portal lets you choose, give documents the larger budget: 100-200 KB keeps every word readable.

Add the photo, crop to the edges of the paper and press Create image. A phone photo of an A4 certificate comes down to 100 KB with the text still readable.
The form wants a PDF under 100 KB, not a JPG.
Use Compress PDF to 100KB for an existing PDF, or JPG to PDF first and then compress it.
