Portals that require 300 KB
Read from each portal's own published instructions, not guessed. These name 300 KB as the minimum, the maximum, or both:
What resolution is realistic at 300 KB
Compress any photo or scan to exactly 300 KB — the limit set by GATE, RRB, RRB.
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 300 KB. Cutting the pixel dimensions only happens when quality alone cannot reach the target, and the larger the target, the less often that is needed — at 300 KB an ordinary photo more often reaches the target on quality alone, with its original dimensions left untouched.

300 KB questions
What resolution will I actually get at 300 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 300 KB. Dimension reduction is only the fallback for when quality alone cannot reach the target, and the smaller the target, the more often that fallback is needed — at 300 KB an ordinary photo more often reaches the target on quality alone, with its original dimensions left untouched.
