What DPI should the images be?

200 DPI. At that resolution the photo is 276×354 pixels and the signature is 276×118 pixels, our resizers output exactly these.

Can I reuse the same photo across TNPSC exams?

Yes, while it remains recent (within 3 months of the application) and matches your current appearance. Update your OTR images when the photo ages out.

TNPSC Photo & Signature Specifications, Explained

Most application rejections are image rejections. The specification is strict but simple once you see it in one place.

Step 1
Photograph: 3.5cm × 4.5cm, 20-50KB
A recent (within 3 months) passport-style photo on a plain white background, 200 DPI, saved as Photograph.jpg between 20KB and 50KB. Face straight to camera, no shadows, no filters.
Step 2
Name and date on the photo, when asked
Some notifications require your name and the date the photo was taken printed at the bottom of the photograph. Check your notification's annexure; add it only if asked.
Step 3
Signature: 3.5cm × 1.5cm, 10-20KB
Sign in your normal running handwriting with a dark pen on white paper. Block or capital letters are rejected. Save as Signature.jpg between 10KB and 20KB.
Step 4
Common rejection reasons
Coloured or patterned backgrounds, old photos, stretched or squeezed images, selfies, signatures in capitals, and files outside the size window. All avoidable in one careful attempt.
