NDAPhoto & Signature Upload Requirements Guide

The UPSC National Defence Academy Exam (NDA) mandates that every candidate upload a strictly compliant passport-style photograph and a handwritten signature during online registration. Non-compliant files are among the most common reasons for form rejection before the application is even reviewed. For the NDA photo size, the required pixel dimensions are 350 x 350 pixels, with a file size between 20 KB and 300 KB in JPEG format. The background must be plain white. Additionally, the NDA portal requires the candidate's name and the date the photograph was taken to be printed at the bottom of the image — a unique step that our tool handles automatically. For the NDA signature size, your handwritten signature on white paper must be scanned or photographed to produce an image of 350 x 350 pixels, compressed to 20–300 KB. Signatures must be written using black or blue ink and must not be in capital letters. Our free online NDA photo resize tool compresses and crops both files locally inside your browser — your images are never uploaded to any server. Specifications are sourced directly from the 2026 Notification and last verified on 2026-05-10.

How to Resize NDAPhoto & Signature Online

1
Select the asset type
Click the 'Photo' tab to resize your photograph, or the 'Signature' tab to process your signature scan. Both use separate NDA-specific dimension presets.
2
Upload your image file
Click the upload area or drag-and-drop a JPEG, PNG, or WEBP file (maximum 10 MB). The tool will load a live preview of your image immediately.
3
Crop to the correct frame
Drag the crop handles to frame your face or signature correctly. The tool enforces the exact 350:350 pixel ratio for photos and automatically adds a white text strip at the bottom for the name and date overlay.
4
Enter your name and photograph date
Type your full name and the date the photo was taken in the provided fields. This text will be rendered inside the white strip at the bottom of the output JPEG, exactly as NDA requires.
5
Set the file size target (20–300 KB for photo)
Move the quality slider to hit your target file weight. The tool's binary-search quality loop will automatically adjust JPEG compression to produce a file within the 20–300 KB range required by NDA.
6
Download the compliant JPEG
Click 'Download Resized JPG' to save the output file. The downloaded file meets the exact NDA photo size and signature size requirements as per the 2026 Notification.
