Coast GuardPhoto & Signature Upload Requirements Guide

The Indian Coast Guard Navik / Yantrik Exam (Coast Guard) 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 Coast Guard photo size, the required pixel dimensions are 350 x 450 pixels, with a file size between 10 KB and 40 KB in JPEG format. The background must be light-colored. The Coast Guard portal does not require any printed text overlay on the photograph. For the Coast Guard signature size, your handwritten signature on white paper must be scanned or photographed to produce an image of 280 x 120 pixels, compressed to 10–30 KB. Signatures must be written using black or blue ink and must not be in capital letters. Our free online Coast Guard 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 Guidelines and last verified on 2026-04-30.
