Signature Size Requirements for Exams

Virtually all major exam authorities—including Staff Selection Commission (SSC CGL, CHSL, MTS), IBPS, State Public Service Commissions, and NTA—require uploaded signature photos to strictly fall between 10KB and 20KB (dimensions ~140×60 pixels). If your file is 21KB, the portal will immediately trigger an error. Compressify gives you real-time byte readout control so you can land precisely inside the 10KB to 20KB window.

📋 20KB Signature Preparation Checklist

Sign in Black Ink: Black ink on plain white paper produces higher contrast and clearer text lines.
Crop Tightly: Remove large blank margins around the signature before compressing.
Recommended Resolution: Set max width/height to 300px–400px.
Format: Save output as JPEG/JPG format.

Frequently Asked Questions

Why does my signature look faint?

If you signed with a light blue pen or took a photo in dim light, contrast will drop. For best results, use black ink and photograph under bright natural light.

Is my signature image safe on Compressify?

Yes. Compressify is 100% serverless. Your signature image is processed locally inside your web browser and is never stored, logged, or transmitted anywhere.
