Official UPSC 2026 & OTR Photograph Specifications
The Union Public Service Commission (UPSC) implements strict photographic and biometric validation rules for the One Time Registration (OTR) portal and applications for exams like Civil Services Examination (CSE), NDA, CDS, and CAPF. Any deviation in image dimensions, date stamp recency, or facial clarity leads to application rejection during preliminary scrutiny.

Mandatory Name and Date of Photograph (DOP) Rule for UPSC
UPSC has introduced a strict guideline for photographs uploaded on the OTR portal:
- The photograph must not be older than 10 days from the date of online application opening.
- The candidate's full name and the date on which the photograph was taken must be clearly printed in legible, dark text on a white strip at the bottom of the photograph.
- The candidate's face must occupy at least 75% of the total photograph area.
- The appearance must match your look in all stages of the examination (Prelims, Mains, and Personality Test/Interview). For instance, if you upload a bearded photograph, you must maintain that appearance during the interview.
Step-by-Step Guide: How to Prepare Your UPSC Photo & Signature
- Take a Bright Frontal Portrait: Stand in front of a white wall or backdrop in a well-lit room. Look straight into the camera with both ears and eyes visible. Do not wear sunglasses or hats.
- Open SizeSnap UPSC Resizer: Navigate to UPSC Photo & Signature Resizer.
- Upload Image & Enter Details: Input your full registered name (in CAPITAL letters, e.g.
VISHAL PATEL) and the date of capture (e.g.12-02-2026). - Adjust Face Oval: Ensure your head and shoulders fill 75% of the 1:1 framing box.
- Download Compliant JPG: Click download. SizeSnap automatically formats the image to 500 × 500 pixels and balances compression so the file size sits comfortably between 40 KB and 150 KB (well within the 20 KB to 300 KB requirement).
UPSC Signature Guidelines (20 KB to 300 KB)
Signatures on UPSC portals must adhere to strict biometric standards:
- Ink: Sign using a black ink pen on fresh, unlined white paper. Black ink provides superior contrast when scanned.
- No Capital Letters: UPSC specifically rejects signatures made entirely in BLOCK CAPITAL letters. Only natural, cursive running handwriting is accepted.
- Aspect Ratio: UPSC expects a square 1:1 frame (minimum 350 × 350 pixels). When uploading a standard rectangular signature, center it within a square canvas with a clean white margin.
- If your scanned signature looks grey or has background shadows, check out our guide on How to Resize Signature for Online Applications or crop it with SizeSnap Signature Tool.
Common Reasons UPSC Applications Get Flagged or Rejected
⚠️ Watch Out For These Disqualifications:
- Old Photographs: Submitting photos older than 10 days violates official UPSC terms.
- Missing Name or Date: An ordinary passport photo without the printed name and DOP strip will be flagged during document verification.
- Spectacles Reflection: Glare on spectacle lenses that obscures the pupils will result in immediate rejection. Remove spectacles before taking the picture.
- Distorted Aspect Ratio: Stretching a portrait into a square manually produces facial distortion. Always crop using an aspect ratio lock.
Frequently Asked Questions (FAQs)
Can I edit or change my UPSC OTR photo after submission?
UPSC permits a 7-day correction window after the close of the application period for each respective examination cycle. However, it is always recommended to upload a compliant photo initially to avoid last-minute portal slowdowns.
What if my signature file is below 20 KB?
The UPSC portal will throw an error such as "File size is less than 20 KB". If your file is too small, use our SizeSnap Image Resizer to re-export at high DPI or adjust quality to exceed 25 KB.
