UPSC Photo & Signature Upload Guidelines (CSE, NDA, CDS)
Official specifications for Union Public Service Commission online applications: photo dimensions, signature rules, date stamping, and OTR compliance.
UPSC online applications (CSE, NDA, CDS, CAPF) require a passport photograph between 20KB and 300KB (350×350 pixels minimum, 1000×1000 maximum) with candidate name and date of photo printed below, and a signature between 20KB and 300KB (350×350 pixels minimum) in JPG format.
Why It Matters
The Union Public Service Commission (UPSC) enforces strict One Time Registration (OTR) and application guidelines. Unlike state exams with tiny 50KB limits, UPSC allows up to 300KB but requires a minimum of 20KB and 350×350 pixels. Photos older than 10 days from the opening of the application window, or photos lacking candidate name and capture date, are strictly disqualified.
UPSC OTR and Photograph Regulations
Under updated UPSC guidelines, the candidate photograph must not be more than 10 days old from the date of online application opening. The face must occupy at least 3/4th (75%) of the total image frame, showing a clear, front-facing appearance with neutral expression.
Crucially, the candidate's name and the exact date on which the photograph was taken must be clearly inscribed at the bottom of the photograph. The background must be plain white or light-colored without shadows, and both ears must be clearly visible.
- Recency: Photo must not be more than 10 days old from the application window start.
- Facial Proportion: Face must cover approximately 75% of the total frame height.
- Mandatory Inscription: Full candidate name and Date of Photo (DOP) printed at bottom.
Dimensional and Pixel Rules for UPSC Portal
The UPSC portal accepts photographs with identical width and height constraints: minimum 350 pixels by 350 pixels, up to a maximum of 1000 pixels by 1000 pixels. The file size must strictly fall between 20 KB and 300 KB.
The signature file follows the exact same resolution rules: square or proportional framing with minimum 350×350 pixels up to 1000×1000 pixels, and file size between 20 KB and 300 KB. Signing with dark black ink on white paper prevents automated scanner rejection.
Appearance Consistency Across Exam Stages
UPSC guidelines stipulate that a candidate's physical appearance at the Preliminary Exam, Mains Exam, and Personality Test (Interview) must match the uploaded photograph.
If a candidate uploads a photograph with a beard, they should appear with a beard throughout all exam stages; if clean-shaven, they must maintain that appearance to prevent biometric verification delays at exam centers.

Step-by-Step Workflow
1. Capture Fresh Headshot
Take a front-facing photo in good lighting against a plain white wall.
2. Add Name and Date Strip
Use ToolMela Name & Date Stamper to apply your full name and recent date.
3. Resize to 500×500 px
Scale the image to standard 500×500 or 600×600 pixels to sit comfortably in the 350–1000 px range.
4. Target 50KB–150KB
Compress the file between 50KB and 150KB, comfortably within the 20KB–300KB allowance.
5. Format Signature
Sign on white paper with black ink, crop cleanly, and ensure resolution exceeds 350×350 pixels.
Professional Best Practices & Pro Tips
- •Do not upload photos where your face occupies less than 70% of the frame; wide shots are rejected by the UPSC OTR reviewer.
- •Ensure the date stamped on the photo falls within the prescribed 10-day application period.
- •Always sign with black gel or ink pen; blue ink can wash out under high-speed scanners.
- •Check your OTR profile photo before applying for individual examinations (CSE, NDA, CDS).
A Civil Services aspirant was updating their UPSC OTR profile. Their original phone camera image was 4.2MB (3000×4000 px). Using ToolMela UPSC Photo Resizer, they cropped the photo to 600×600 pixels (75% face coverage), added their name and today's date stamp, and exported a clean 85KB JPG that uploaded instantly to the UPSC portal.
Common Mistakes to Avoid
Technical Realities & Limitations
Once an application is finalized, changing uploaded photos requires an official correction window, which may carry administrative charges.

No. Eyeglasses, spectacles, and sunglasses are strictly prohibited to ensure clear biometric facial recognition.
What pixel dimensions are best for UPSC uploads?
A square image of 500×500 or 600×600 pixels at around 50KB–150KB provides optimal sharpness and complies with the 350–1000 pixel requirement.
