India's defense exam ecosystem

Becoming an officer in the Indian Armed Forces requires clearing one of several entry pathways, each with its own examination:

• UPSC NDA (National Defence Academy): Pre-graduation entry for Army, Navy, Air Force after Class 12. Conducted twice yearly by UPSC.
• UPSC CDS (Combined Defence Services): Post-graduation entry for IMA, OTA, INA, AFA. Conducted twice yearly by UPSC.
• UPSC ESE (Engineering Services Examination): For technical officer entries in Indian Engineering Services. Civilian-side but UPSC-conducted.
• AFCAT (Air Force Common Admission Test): For Air Force ground duty branches and technical entries. Conducted by Indian Air Force, not UPSC.
• INET (Indian Navy Entrance Test): For Indian Navy permanent and short service commission. Conducted by Indian Navy.
• Service-specific Entries: SCS (Service Cadets Scheme), TES (Technical Entry Scheme), University Entry Scheme — each with its own application portal.

Most aspirants apply to multiple exams: NDA + CDS + AFCAT + INET is a common combination. The photo specifications are similar across all but slightly differ between UPSC-conducted and service-conducted exams.

UPSC CDS, NDA, ESE — official photo and signature spec

UPSC publishes a unified set of specifications for all its conducted exams. CDS 2026, NDA 2026, ESE 2026 all use the same upload portal (upsconline.nic.in):

Photo

• Format: JPG / JPEG only (PNG rejected)
• File size: 20 KB to 300 KB (UPSC's portal is more flexible than NTA)
• Dimensions: 110 × 135 px minimum to 4500 × 5500 px maximum (passport ratio 3.5:4.5)
• Background: Plain white or off-white
• Recency: Photo taken within last 6 months
• Visibility: Face clearly visible, both eyes open, looking directly at camera, neutral expression
• Coverage: Approximately 70-80% of frame should be your face

Other documents

UPSC exams may require uploading category certificate (SC/ST/OBC-NCL/EWS/PwD), domicile certificate, age proof. Each has separate file limits — typically 50-200 KB JPG or PDF.

AFCAT 2026 — Indian Air Force entrance spec

AFCAT is conducted by the Indian Air Force directly, not UPSC. The portal at afcat.cdac.in has its own validation rules:

Photo

• Format: JPG / JPEG only
• File size: 10 KB to 50 KB (stricter upper limit than UPSC's 300 KB)
• Dimensions: 3.5 × 4.5 cm (350 × 450 px)

• Dimensions: 140 × 60 px
• Color: Black ink on white paper

AFCAT-specific notes

• Strict file size cap: AFCAT's 50 KB upper limit is the tightest among defense exams. Don't try to upload UPSC-spec 200 KB photos.
• Application fee: Most candidates pay ₹250. NDA cleared candidates and previous AFCAT applicants may have different fees.
• Branch selection: Choose Flying Branch, Ground Duty (Technical/Non-Technical), Logistics, Education, or Meteorology at application time.

• Application fee: ₹215 for general candidates; reserved categories exempt.
• Online + SSB: Online test followed by SSB interview at one of three Naval Selection Boards (Bhopal, Bangalore, or Kolkata).

Why defense exam applications get rejected

1. Wrong file format like PNG/HEIC (18%). All defense portals require JPG. iPhone HEIC photos and PNG screenshots are rejected.
2. File too large for AFCAT (15%). AFCAT caps at 50 KB. Photos that pass UPSC (300 KB) and INET (200 KB) fail AFCAT.
3. Background not white (12%). Coloured walls, patterned wallpaper, blurred backgrounds.
4. Smiling broadly (11%). Defense exams require formal, neutral expression — particularly for SSB interview standard.
5. Wearing glasses with reflections (10%). Anti-reflective lenses preferred; reflective ones rejected.
6. Wrong dimensions (9%). Square crop instead of 3.5:4.5, or photo with too much margin.
7. Photo too dark or too bright (7%). Phone over-correction.
8. Signature in blue ink (6%). Black ink only.
9. Photo and signature swapped (4%). Defense portals have separate slots; double-check.
10. Other (8%). Old photos, corrupted files, etc.

The "wrong format" issue is the biggest specific to defense exams — these portals have stricter format validation than NTA or NEET.

Step-by-step: defense exam photo workflow

1. Take a phone photo against a plain white wall. Use natural daylight. Have someone hold the phone at your eye level 1-1.5 m away. Take 10-15 shots, pick the best.
2. If iPhone, ensure JPG format. Settings → Camera → Formats → "Most Compatible." Defense portals strictly reject HEIC.
3. Open ShrinkTo's ID photo creator. Browser-based, no upload.
4. Pick the "UPSC / NEET / JEE" preset. 3.5×4.5 cm dimensions, fits all defense exams.
5. Drop your photo. Cropper opens with passport ratio locked.
6. Adjust the crop. Top of head 1 cm from top, face fills 70-80%. Wear formal clothing (defense applications value smartness).
7. Click Generate. Tool resizes to 350×450 px and binary-search-compresses. Aim for 30-40 KB to satisfy AFCAT's 50 KB cap and other exams' wider ranges.
8. Verify the output. Dimensions ✓, file size ✓ (under 50 KB), JPG format ✓, white background ✓, neutral expression ✓.
9. For signature: Sign with black pen on white paper, photograph or scan, compress to 5-30 KB at 350×150 px.
10. Save with clear filenames. "defense_photo_2026.jpg" and "defense_signature_2026.jpg".
11. Upload to UPSC, AFCAT, INET portals. One file works for all.

SSB interview photo requirements

If you clear written examinations (CDS/NDA/AFCAT/INET), you'll be called for the Services Selection Board (SSB) interview — a 5-day assessment held at one of multiple SSB centres across India.

Photos required at SSB

• 6 unsigned photographs: Bring 6 physical 3.5×4.5 cm photos to your SSB appointment. Used for various forms during the 5-day assessment.
• Photographs of family members: Some SSB centres ask for separate photos of immediate family members. Specifications: any size, photographs labeled with name and relation on the back.
• Photo of you in uniform/formal: If you have prior service experience, bring a photo in service uniform (optional but valued).

Why physical photographs at SSB

SSB is a 5-day high-stakes assessment. Each interviewer needs a photo for their files. Each form (Personal Information Questionnaire, Picture Perception Test, Group Tests) often gets a copy. The 6 photographs ensure enough copies for all paperwork.

Common mistakes that cause defense exam rejection

• Photo over AFCAT's 50 KB limit. The same photo may pass UPSC (limit: 300 KB) but fail AFCAT (limit: 50 KB). Aim for under 50 KB to satisfy all defense exams.
• Smiling in the photo. Defense exams expect formal expression. Even slight smiles can cause SSB-level scrutiny.
• Casual clothing. Defense applications value smart appearance. Wear a formal shirt with collar (avoid t-shirts, casual wear).
• Long hair covering face. Both eyes and forehead must be clearly visible. Defense recruiters specifically look for grooming standards.
• Visible facial hair if you're attempting officer cadre. Officer cadre (NDA, IMA, OTA) values clean-shaven look. Attempt to be clean-shaven for the photo.
• Photo not in focus. Defense exams use the photo for facial recognition during SSB. Out-of-focus photos cause issues.
• Tinted or reflective glasses. Use clear, anti-reflective glasses or remove for the photo.
• Wrong file format. JPG only. PNG, HEIC, BMP all rejected by defense portals.
• Forgetting that AFCAT and INET have their own portals. Each defense exam has a separate registration. UPSC, AFCAT, INET — three different portals, three separate registrations.

Advanced tips for defense aspirants

• Apply to multiple defense exams in the same year. NDA + CDS + AFCAT + INET is a strategic combination — different services, different selection criteria, more chances of success.
• Use the same photo file for all defense exams. Save once, upload everywhere. The 30-50 KB range works for all four exam portals.
• Track each portal's individual deadlines. UPSC has fixed slots. AFCAT and INET schedules are independent. Keep a spreadsheet with deadlines, registration numbers, and photo upload status.
• Prepare physical photos for SSB: Order 10-12 prints of your defense photo from a studio. Keep them ready — you'll need them for SSB if shortlisted.
• For NDA aspirants under 18: Photo must be your current appearance. Even though you may not look like an "officer" yet, the SSB will see you in person — try to look smart and groomed.
• For CDS / OTA (non-IAF) candidates: Physical fitness is critical. Your photo doesn't show fitness, but SSB does. Don't take a photo that suggests illness or unhealthy appearance.
• Save the application receipts. All four defense portals issue unique application IDs. Save these in cloud storage. You'll need them for admit cards, results, SSB call letters.
