How the 50KB Compression Works
- Binary search on JPEG quality: the tool re-encodes your photo at progressively lower JPEG quality (start at 85%, drop until file fits 50 KB).
- Auto-downscale if needed: if even quality 5% can't reach 50 KB, the tool reduces pixel dimensions in 15% steps.
- Output as JPG: universally accepted by all Indian government and exam portals.
- Browser-only: all work happens in your browser via Canvas API — your photo never leaves your device.
