Portals that require 100 KB
Read from each portal's own published instructions, not guessed. These name 100 KB as the minimum, the maximum, or both:
What resolution is realistic at 100 KB
Compress any photo or scan to exactly 100 KB — the limit set by AFCAT, CTET, JEE Main, NEET (UG), UPSC.
The tool tries quality first: it re-encodes your photo at a range of JPEG quality settings, narrowing in with a binary search, and keeps the largest result that still lands at or under 100 KB. At a target this small, a photo of any real size and detail usually cannot get there on quality alone — the search runs out of room, and the tool starts cutting the pixel dimensions in steps, re-encoding after each cut, until it fits. The result and the log both say when that happened. A simple, low-detail image, a scanned signature being the common case, is more likely to reach 100 KB with its original dimensions untouched.

100 KB questions
What resolution will I actually get at 100 KB?
The tool always tries quality first: it re-encodes your photo at a range of JPEG quality settings, narrowing in with a binary search, and keeps the largest result that still lands at or under 100 KB. At a target this small, a photo of any real size and detail usually cannot get there on quality alone — the search runs out of room, and the tool starts cutting the pixel dimensions in steps, re-encoding after each cut, until it fits. The log shows both kinds of pass. A simple, low-detail image, a scanned signature being the common case, is more likely to reach 100 KB with its original dimensions untouched.
