Many Indian government exam portals require photos under 50 KB — including UPSC (20–50 KB), SSC (20–50 KB), IBPS (under 50 KB), and several state PSC portals. This guide explains how to compress any JPEG or PNG to exactly 50 KB or less, why naive compression tools overshoot or undershoot, and how our tool hits the target precisely.
Why 50 KB Is a Tricky Target
Unlike a "maximum 500 KB" limit where anything smaller is fine, the UPSC portal (and several others) requires a file to be both above a minimum (20 KB) AND below a maximum (50 KB). This means you can't just compress aggressively — you need to hit a specific range. Most free compression tools work by percentage reduction, not by a target file size, which makes them unreliable for portal submissions.
Which Portals Require Under 50 KB?
| Portal / Exam | Photo Requirement | Signature Requirement |
|---|---|---|
| UPSC (IAS/IPS/IFS) | 20–50 KB JPEG | 10–20 KB JPEG |
| SSC (CGL / CHSL / MTS) | 20–50 KB JPEG | 10–20 KB JPEG |
| IBPS / SBI (bank exams) | Under 50 KB JPEG | Under 20 KB JPEG |
| RRB (Railway exams) | 20–40 KB JPEG | 10–20 KB JPEG |
| NDA / CDS | Under 50 KB JPEG | Under 30 KB JPEG |
| Various State PSCs | 20–50 KB JPEG (typical) | 10–20 KB JPEG (typical) |
How to Compress a Photo to 50 KB Using Our Tool
Step 1: Open Compress Image
Go to our Compress Image tool. No account or sign-up required. Your image is processed entirely in your browser — it never touches a server.
Step 2: Upload your photo
Upload your JPEG or PNG photo. The tool supports files up to 20 MB as input. If you're starting with a camera photo (typically 2–8 MB), this is fine.
Step 3: Set a target size
Switch to "Target Size" mode and enter 40 KB. This gives you a 10 KB safety margin below the 50 KB limit. The tool uses binary search compression to hit within 1–2 KB of your target.
Step 4: Download and verify
Download the compressed image. Right-click → Properties to confirm the file size. It should be between 38–44 KB — safely within the 20–50 KB UPSC range. Check that text and facial features are still clearly visible before uploading to the portal.
Tips for Best Quality at 50 KB
- Start with a high-resolution source photo (at least 600×800 px) — the compressor has more quality to work with
- Crop out any unnecessary background before compressing — less image area = better quality at the same file size
- Use JPEG format, not PNG — JPEG compresses photos much more efficiently (PNG is lossless and stays large)
- Avoid compressing an already-compressed image — "recompressing" JPEG causes visual artefacts
- If the compressed photo looks blurry, your source photo was too low-resolution to start with
