Which portals require photos under 40KB?
40KB sits between the 20–50KB range used by most government recruitment portals. Several ESIC regional exams, state PSC boards, and municipal corporation recruitment portals specify exactly 40KB. It's also a common limit on older government portal infrastructure that hasn't updated its size limits.
| Portal / Exam | Photo Size | Dimensions | Format |
|---|---|---|---|
| ESIC SSO / MTS | ≤ 40KB | 200 × 230 px | JPEG |
| State PSC (various) | ≤ 40KB | 200 × 230 px | JPEG |
| Municipal Recruitment Portals | ≤ 40KB | 200 × 230 px | JPEG |
| ECIL Recruitment | ≤ 40KB | 200 × 230 px | JPEG |
| HAL Recruitment | ≤ 40KB | 200 × 230 px | JPEG |
| BEL Recruitment | ≤ 40KB | 200 × 230 px | JPEG |

Frequently asked questions
Is 40KB the same as 40,000 bytes?
In most portal validation contexts, yes — 40KB means 40 kilobytes, typically interpreted as 40,000 bytes (not 40,960 bytes). This tool targets 40KB conservatively so your file stays under the limit on any portal's interpretation.
Will my photo still look clear at 40KB?
Yes for passport-style photos. A standard 200×230px face photo compresses to 40KB at roughly 80–85% JPEG quality — the difference is invisible on screen. The tool shows a before/after preview so you can verify before downloading.
Can I use PNG for government portals?
Most Indian government portals require JPEG only. PNG is commonly rejected. This tool outputs JPEG automatically when you compress — no separate conversion needed.
