Frequently Asked Questions
What is the difference between 20KB and 40KB for exam portals?
Both are standard sizes for Indian government exam portals. SSC CGL and IBPS use 20KB limits; UPSC CAPF, TNPSC, and several state PSC exams use 40KB limits. Check your specific portal's instructions to confirm which limit applies. If in doubt, compressing to 20KB is accepted by all portals that accept 40KB.
Will my photo look clear at 40KB?
At 40KB, a passport-sized JPG (200×230 pixels) is perfectly clear for portal display and identity verification purposes. The photo will appear sharp on any screen. It is not intended for large-format printing.
My photo is 5MB. Can it be reduced to 40KB?
Yes. A 5MB phone photo is typically 4000×3000 pixels. Scaling it to 200×230 pixels and re-encoding as JPG produces a file well under 40KB with the face remaining clearly visible.
Which Exam Portals Require a 40KB Photo?
| Exam | Document | Size Limit | Dimensions | Format |
|---|---|---|---|---|
| UPSC CAPF | Photo | Up to 40KB | 3.5 × 4.5 cm | JPG |
| TNPSC Group 1/2/4 | Photo | 20KB–40KB | 3.5 × 4.5 cm | JPG |
| SSC MTS | Photo | Up to 40KB | 200 × 230 px | JPG |
| State PSC exams | Photo | 20KB–40KB | 3.5 × 4.5 cm | JPG |
| Police Bharti | Photo | Up to 40KB | 3.5 × 4.5 cm | JPG |
| BPSC | Photo | Up to 40KB | 3.5 × 4.5 cm | JPG |
How Many Pixels is a 40KB Image?
A 40KB JPG at standard quality settings typically corresponds to:
- 200 × 230 pixels at JPG quality 80 ≈ 25–45KB ✓ (ideal for most portals)
- 250 × 300 pixels at JPG quality 70 ≈ 35–50KB ✓
- 350 × 450 pixels at JPG quality 60 ≈ 35–50KB ✓
White backgrounds compress far better than coloured backgrounds. The same photo against a white wall will be significantly smaller than the same photo against a coloured background at identical pixel dimensions.
Step-by-Step: Convert Your Image to 40KB
