CDS 2026 Photo Specifications (Official UPSC Requirements)
CDS photo requirements are set by UPSC and must be followed exactly during registration on upsconline.nic.in. Here are the complete, official specifications:

Compress Your CDS Photo FreeCDS Registration Timeline & Photo Upload Process
Unlike UPSC CSE (which has one notification), CDS has two registration windows per year. Understanding the timeline helps you prepare your photo in advance.
CDS I Timeline (Feb Exam)
- October: UPSC releases notification with photo specifications
- November: Registration opens on upsconline.nic.in - upload your compressed photo here
- December: Registration closes, admit card released
- February: Written exam conducted
Key action: Have your compressed photo ready by late October to upload during the November window.
CDS II Timeline (Sep Exam)
- May-June: UPSC releases notification - photo specs may be updated
- June-July: Registration window - upload compressed photo
- August: Admit card released
- September: Written exam conducted
Key action: Check the official notification in May-June as specs can change slightly between CDS I and II.
CDS vs NDA vs UPSC CSE: Why Photo Requirements Are Identical
All three exams are UPSC-conducted and use the same online portal (upsconline.nic.in) and identical photo specifications. However, they differ in eligibility and positions offered:
| Exam | Eligibility | Photo Specs | Positions |
|---|---|---|---|
| CDS | Graduate, any branch | 20-200KB JPEG, white bg | Defence officers (Army, Navy, Air Force) |
| NDA | 12th pass (12+2/A-level) | 20-200KB JPEG, white bg | Defence officers (Army, Navy, Air Force, Coast Guard) |
| UPSC CSE | Graduate, any branch | 20-200KB JPEG, white bg | IAS, IFS, IPS, and other civil services |
Conclusion: If you prepare a photo for CDS, the same file works for NDA and UPSC CSE applications. All three are on the same portal with identical specs.
How to Prepare Your CDS Photo (Step-by-Step)
Follow these steps to ensure your photo meets all UPSC requirements and passes the automated verification system:
- Take a passport-size photo with plain white background: Use a white wall or backdrop, good natural lighting, and a simple smartphone camera. Ensure your face occupies 75% of the frame and both ears are visible. No glasses, caps, or accessories unless required for religious reasons.
- Check file size - must be between 20KB and 200KB: Most smartphone photos are 1-5MB. You need significant compression. Use ImageResizer and set target to 190KB (safe below the 200KB limit).
- Verify JPEG format (.jpg or .jpeg extension): If your photo is PNG, HEIC, or BMP, convert to JPEG first using ImageResizer (it handles conversion during compression).
- Preview the final photo before uploading: Open the compressed file to verify face coverage, white background, and file size. Check both the preview and file properties (right-click > properties > size).
- Submit during registration window at upsconline.nic.in: During the CDS notification period, log in to your UPSC account and upload the photo via the registration form. You'll upload both photo and signature.
Free compression tool: ImageResizer compresses CDS photos to 20-200KB exactly. No sign-up, no upload to our servers. All processing happens on your device.
Common CDS Photo Mistakes (and How to Avoid Them)
These are the top reasons for CDS photo rejection (contributing to the 10-12% rejection rate):
- Wrong background color: Cream, off-white, or pale backgrounds are rejected. Use pure white only. Common in formal settings - verify before uploading.
- File size outside 20-200KB range: Too small (under 20KB) is blurry; too large (over 200KB) is rejected. ImageResizer with 190KB target solves this.
- Using PNG or HEIC instead of JPEG: The portal only accepts JPEG. Convert before uploading using ImageResizer.
- Face covers less than 75% of photo: Large margins or unusual framing causes rejection. Crop tightly - face should dominate the frame.
- Old photo (more than 6 months old): UPSC may reject photos that appear old. Take a fresh photo if yours is over 6 months old.
- Glasses or headwear (except religious wear): No sunglasses, caps, hats, or hoods. Religious headwear is acceptable, but face must still be clearly visible.
Frequently Asked Questions About CDS Photo Requirements
CDS requires photos between 20KB and 200KB in JPEG format. Target 190KB when compressing to have a safe margin below the limit. Smartphone photos (typically 2-5MB) need significant compression via tools like ImageResizer.
No. CDS explicitly requires JPEG/JPG format only. The UPSC portal will reject PNG, HEIC, BMP, or other formats. If your photo is in PNG or HEIC (common on iPhones), convert to JPEG first using ImageResizer or an image converter.
Yes. Both NDA and CDS are UPSC-conducted and use the same portal (upsconline.nic.in) with identical photo specifications (20-200KB JPEG, white background, passport size). One prepared photo works for both applications.
Twice. CDS I is conducted in February (notification in October, registration in November). CDS II is conducted in September (notification in May-June, registration in June-July). Candidates can apply for both in the same year.
Plain white background only. Cream, off-white, or any coloured/patterned background will be rejected. This is a common reason for CDS photo rejection (part of the 10-12% rejection rate). Use a white wall or white backdrop.
At least 75% of the photo must show your face. Eyes, nose, mouth, and both ears must be clearly visible. No large margins. The portal has automated checks for face coverage, so ensure your face dominates the frame.
You can use an existing passport photo if it meets CDS specs (20-200KB, white background, 75% face coverage). However, passport photos are often stored in larger file sizes (500KB-2MB) and may have slightly different backgrounds. Compress it to verify it meets CDS requirements.
The portal provides specific error messages (e.g., "File size exceeds limit", "Background not white", "Face not visible"). You can re-upload during the registration window (typically 2-3 weeks). Verify specs and re-compress using ImageResizer, then upload again before the deadline.
