Applying for government exams can be stressful, and file upload validators are notoriously strict. Many state commission portals, such as WBPSC, DSSSB, and JSSC, require candidate photos and signatures to be kept under 40KB.
If your uploaded photo is even slightly over 40KB (e.g., 40.2KB), the portal will reject it. This guide outlines how to easily resize and format files for successful uploads.
Why 40KB Portals Reject Uploads
Submissions usually fail due to:
- Incorrect File Extension: Renaming a `.png` file to `.jpg` manually without converting the format causes checking algorithms to flag the file as corrupt.
- No Padding/Margin: If your compression reaches exactly 40KB, system round-offs on the server side might register it as 40.01KB. Aim for a safe zone around 35-38KB.
How to Format Your Image for 40KB
- 1
Go to the OptiKit 40KB Tool.
- 2
Upload your passport photograph or signature scan.
- 3
The application will automatically scale the pixel dimensions and output a sharp JPEG under 40KB.
