Complete Guide: Image KB Size Requirements for Indian Competitive & Recruitment Exams (2026)
Applying for government recruitment notifications (UPSC CSE, SSC CGL, CHSL, RRB NTPC, IBPS PO) or national entrance examinations (JEE Main, NEET UG, CUET) requires uploading passport photos, signatures, and thumb impressions adhering strictly to KB file size limits. Uploading improperly sized images leads to online application rejection.

Frequently Asked Questions (FAQ)
Q.Why does PNG format not compress to extremely low sizes?
PNG is a lossless format designed to retain pixel-perfect details, so it does not support variable compression quality parameters. If you need to fit a strict exam upload size like 20KB or 50KB, we suggest selecting the Output Format as JPEG or WebP.
Q.Will my original image quality be ruined?
No. Our engine uses smart compression loops which optimize quality first. If the file size remains too large, it scales down the pixel count moderately so that the image stays sharp and clear.
Q.Does this tool upload my documents online?
No. All calculations, compression matrices, and downloads are done client-side within your browser. None of your photos ever leave your computer.
