The 30KB Limit
The tightest file ceiling of any spec on this site.
Kazakh digital submissions are capped at around 30KB. For comparison, Kuwait allows 120KB and most portals allow 2MB — 30KB is exceptionally small for a photo that still has to be sharp enough for facial recognition.
Treat it as a compression problem, not a cropping one. Keep the pixel dimensions the spec needs and lower the JPEG quality until the file fits. Shrinking the image instead leaves the face too small to verify.
