A real moment
“Your TNPSC photo uploaded, but it is a phone selfie with no name strip, and TNPSC says a photo like that can get the application rejected.”
The photo is a recent colour studio photo on a white background, 4.5 cm tall and 3.5 cm wide, with your name and the date of photography printed at the bottom, saved as a 20 to 50 KB JPG at 200 DPI. The signature, in blue or black ink inside a 6 x 2 cm box, is a 10 to 20 KB JPG.

A studio photo, not a selfie
TNPSC wants a colour, passport-size photo taken in a photo studio against a white background, showing your face from the front with both ears and part of the neck. It rules out photos taken on a mobile phone, selfies, photocopies, and photos from functions or tourist spots.
Your name and date go on the photo
The name of the candidate and the date the photo was taken must be printed at the bottom of the photo. Of the 4.5 cm height, 3 cm is your face and 1.5 cm is that strip. Ask the studio to print your name and the date on the photo.
How recent the photo must be
At One Time Registration the photo must be taken within the last 3 months. For each application, TNPSC asks for a photo taken on or after the date of that notification, so a photo from your OTR may be too old for a new post.
The signature box
Draw a 6 x 2 cm box on white paper, sign inside it in blue or black ink, and scan it at 200 DPI as a 10 to 20 KB JPG named Signature.jpg. Too big? Use the free signature resize tool at 20 KB. Under 10 KB? Increase image size lifts it just over.
The pixel and DPI figures do not add up
TNPSC gives both 200 DPI and pixel sizes, but at 200 DPI a 3.5 x 4.5 cm photo would be about 276 x 354 pixels, not 130 x 170. We do not convert them for you: meet the KB range and keep the centimetre proportions TNPSC publishes.
Group IV 2026 and OTR
Notification 11/2026 for Group IV lists applications from 6 October to 5 November 2026, 11:59 pm, with corrections from 9 to 11 November and the exam on 10 January 2027. One Time Registration costs Rs 150, lasts 5 years and needs your Aadhaar linked. Check TNPSC's site for changes.
