CDS (Combined Defence Services) shares NDA's UPSC OTR requirements — a square photo of at least 350×350px between 20KB and 300KB, and a triple-stacked signature between 20KB and 100KB. CDS leads to IMA, INA, Air Force Academy, or OTA depending on your preference, and your uploaded photo is compared at every subsequent stage — written exam, SSB interview, and medical — so a clear, current, consistent photo matters more here than a quick fix.
Frequently asked questions
Is CDS photo format the same as NDA?
