Common mistakes to avoid
- Uploading a rectangular passport photo — UPSC's portal expects a square image
- Forgetting the printed name and date on the photograph
- Using a photo older than the notification allows
Pro tips
- Crop to a true square first; a rectangular crop fails UPSC's dimension check
- All UPSC exams (CSE, NDA, CDS, CAPF) share the OTR profile, so one correct set covers them
- Keep the photo around 120–180 KB to stay sharp well inside the 300 KB cap
