How to compress a photo to 20KB for SSC and government forms
A step-by-step guide to reducing photo size for SSC CGL, UPSC, and other Indian government form uploads — without visible quality loss.

Indian government forms — SSC CGL, UPSC, GATE, and dozens of state portals — mandate photo uploads under strict size caps. 20KB, 50KB, 100KB. Miss the target by a byte and the form rejects the upload.
Here's the fastest workflow to hit an exact KB target every time.
The problem with generic compressors
Most compressors expose a quality slider (60%, 70%, 80%). You keep tweaking until the file lands close to the target. That's guesswork and it wastes minutes per form.
The fix: target-KB compression
Use a compressor that takes a **KB target**, not a quality percentage. It runs binary search internally, adjusting quality until the file matches your target within a few hundred bytes.
Step-by-step
- Open the Compress Image tool on ToolBharat.
- Upload your photo.
- Enter your target — e.g. **20 KB**.
- Click Compress. Download.

Preserving quality
Aim for the largest size the form permits — 100KB looks noticeably better than 20KB. If you have a choice, choose the higher cap.
