Uploading the correct photograph and signature is an important part of the UPSC NDA application process. Even if you meet all the eligibility conditions, mistakes in your uploaded images can create problems during application submission and verification.
Many candidates are confused about the correct photo size, signature format, file dimensions, background colour and the new live photograph requirement.
UPSC has also introduced a new online application portal with updated document-upload instructions. One important change is that candidates must upload a passport-size photograph, capture a live photograph and provide three signatures in a single image.
In this article, you will learn the latest UPSC NDA signature photo upload instructions, including image size, file format, signature preparation, live photo capture and the complete application portal process.
We have used the official UPSC application portal instructions as the primary reference. Candidates should also check their examination-specific notification before submitting the form.

2. UPSC NDA Live Photograph Capture Instructions
The live photograph requirement is an important part of the new UPSC application process.
Candidates must capture a live photograph while filling out the application. Uploading only a previously saved passport-size photograph is not sufficient.
According to the official UPSC portal instructions, candidates can capture their live photograph using either of these methods.
Method 1: Capture Live Photograph Using a Device
You can use the webcam of your current device.
Follow these steps:
- Open the photograph capture section.
- Allow the browser to access your camera.
- Position your face properly in front of the camera.
- Make sure the lighting is sufficient.
- Look directly at the camera.

Method 2: Capture Live Photograph Using a Mobile Phone
You can also use a mobile phone to capture your live photograph.
- Open the live photograph capture section on your computer.
- Look for the QR code displayed on the screen.
- Scan the QR code using your mobile phone.
- Follow the instructions displayed on your phone.
- Capture your live photograph.
- Verify that the photograph has been successfully uploaded.
Important Live Photograph Rules
Keep these points in mind:
- Capture your photograph in good lighting.
- Make sure your face is clearly visible.
- Keep your face straight.
- Avoid strong shadows.
- Do not use a photograph of another person.
- The live photograph must match the uploaded passport-size photograph.
UPSC clearly states that if a mismatch is detected between the two photographs, the candidate will not be allowed to proceed further with the examination application process.
Therefore, use photographs showing your actual appearance.
3. UPSC NDA Signature Upload Instructions
The signature process has an important requirement that many candidates may overlook.
UPSC requires candidates to provide three signatures arranged vertically in a single image.

| Paper | Plain white paper |
| Arrangement | Vertically, one below another |
