How exact-KB compression works

This adjusts JPG/WEBP quality and, if needed, slightly reduces pixel dimensions until the file lands just under your target — typically with a small safety margin so a strict portal doesn't reject it for being a byte over. The compression runs on a background thread when your browser supports it, so the page stays responsive even on a large photo. Your file is never sent to a server — everything happens on your device.

When you need a 100 KB photo

The typical photo ceiling for CTET, and a safe mid-point for NEET and JEE Main, both of which allow up to roughly 200 KB but work fine well below that.

Most recent phone or webcam photos still look sharp at this size. If the result looks blurry, the original photo's resolution is usually the real issue.
