How the 30KB 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 30 KB).
- Auto-downscale if needed: if even quality 5% can't reach 30 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.
Frequently Asked Questions
What is the SSC photo size?
100 × 120 pixels (very small — equivalent to 25×30 mm at 100 DPI), 20-50 KB JPG. Plain white background. Recent photo (within 3 months recommended). Face fills 70% of frame.
What is the SSC signature size?
140 × 60 pixels, 10-20 KB JPG. Black ink on white paper, no border.
Why is SSC photo size so small (100×120)?
Legacy standard — SSC online portal was built when bandwidth was limited. The 100×120 size keeps photos under 50 KB which uploaded reliably even on 2G connections in 2013-15. SSC has retained this spec for backward compatibility.
Will my photo look unrecognisable at 100×120?
No — 100×120 is small but clear enough for facial recognition. Face must fill 70% of frame so the head + shoulders are clearly visible. Don't shoot zoomed-out — fill the frame with your head and upper torso.
Can I use SSC photo for IBPS too?
Yes — IBPS specs are nearly identical (200×230 px, 20-50 KB). Use the IBPS-tier 200×230 size for both, and SSC will accept it (their max is 50 KB which 200×230 fits comfortably).
