How to Compress Image to 20KB for SSC

Published: March 2026 • 5 Min Read

The 11th Hour Nightmare

You’ve spent hours filling out the SSC CGL or CHSL form, but the "Submit" button keeps failing. The error? "Image must be between 10KB and 20KB."Standard compressors often leave you at 21KB or turn your face into a blurry mess, leading to manual rejection during verification.

The Exact-Size Hack (Step-by-Step)

To avoid rejection, you need a compressor that understands KB Targeting. Follow these steps to get a perfect result every time:

1

Access the Engine

Go to the ToolKing Image Compressor. Our tool runs locally in your browser, ensuring your personal ID photos stay private.
2

Upload & Target

Select your photo or signature. In the Target Size field, enter 20 and select KB.
3

Fine-Tune (Optional)

If the preview looks too soft, try 19KB. This ensures that even if the govt server calculates size differently, you stay under the limit.
4

Verify & Download

Check the dimensions. Most govt forms require 3.5cm x 4.5cm. Our tool preserves aspect ratios to prevent stretching.

Don't Risk Rejection

Hit the 20KB limit exactly with our AI-powered target compression.

Pro Tips for Exam Photos
