TNPSC Photo & Signature Size 2026: Complete Upload Guide

Published on: August 22, 2026

Uploading documents correctly to the Tamil Nadu Public Service Commission (TNPSC) One Time Registration (OTR) portal is crucial to avoid application rejection.

1. Photo Requirements

Your photograph must be a color passport-size picture taken against a plain white background. It must measure exactly 3.5 cm × 4.5 cm (~276 × 354 pixels at 200 DPI) and have a file size between 20 KB and 50 KB. Crucially, the bottom of the photo must feature a white border strip displaying the candidate name in capital letters and the date of photography.

2. Signature Requirements

Sign within a 6.0 cm × 2.0 cm box on a sheet of white paper using a blue or black ink pen. Scan or photograph the signature clearly. The file must be cropped cleanly with no margins, sized to 230 × 75 pixels, and weigh between 10 KB and 20 KB in JPEG format.

3. Quick Sizing and Conversion

Instead of using complex image editing tools like Photoshop, you can format your photos and signatures automatically with our free online resizer tool. It crops, applies name/date overlays, compresses to compliance limits, and injects the 200 DPI header metadata directly in your browser.
