UPSC Civil Services Exam Photo and Signature Specifications

The Union Public Service Commission (UPSC) conducts the Civil Services Examination (CSE) — India's most prestigious competitive exam — annually. The application process, conducted through the UPSC OTR (One Time Registration) and DAF (Detailed Application Form) portals, requires uploading a photograph and signature with specific technical specifications.

Given the high stakes of the UPSC CSE — with over a million applicants annually — even a minor upload error can cause unnecessary stress and delays. Understanding the exact requirements and preparing your files in advance ensures a smooth application experience.

UPSC Photo Requirements

  • File Size: 20KB to 300KB
  • Dimensions: 350×350 pixels (square), face covering about 75% of the frame
  • Format: JPEG only
  • Background: Plain white or off-white, no shadows or patterns
  • Specifications: Recent photo (within 6 months), no glasses with tinted lenses, both ears visible, neutral expression

UPSC Signature Requirements

  • File Size: 20KB to 100KB
  • Dimensions: About 350 pixels wide and 350–500 pixels tall (portrait)
  • Format: JPEG only
  • Specifications: Sign three times, one below the other, in black ink on white paper
  • Note: These are the commonly published limits. Check the exact numbers on your UPSC form before uploading.

How to Prepare Your UPSC Photo

  1. Take a professional passport photo against a plain white background with uniform lighting. Avoid shadows and reflections.
  2. Open the UPSC photo compressor — a target of 100KB keeps your photo comfortably within the commonly listed 300KB UPSC limit while maintaining excellent clarity.
  3. Upload your original photo and use the quality slider to reach your desired file size. The tool displays real-time output size.
  4. Check the dimensions — UPSC commonly lists 350×350 pixels for the photo. The CompressKaro tool keeps the aspect ratio.
  5. Download the compressed JPEG and verify the file size in your computer properties before uploading to the UPSC portal.

How to Prepare Your UPSC Signature

  1. Sign on clean white paper using black ink. Keep the signature compact and centered.
  2. Scan or photograph the signature at 200-300 DPI. Ensure the image is well-lit and in focus.
  3. Use the signature compressor for a signature written three times, one below the other, as a JPEG of 20KB to 100KB about 350 pixels wide.
  4. Download and verify before uploading to the UPSC portal.

Common UPSC Upload Mistakes

  • File too large: Many applicants upload high-resolution DSLR photos that exceed 100KB. Always use a compressor to bring the size within limits.
  • Wrong background: UPSC strictly requires a plain white or off-white background. Colored backgrounds or patterns will be rejected.
  • Old photograph: Using a photo older than 6 months can cause identity verification issues during the interview stage.
  • Format mismatch: Only JPEG/JPG is accepted. Never upload PNG files even after renaming the extension.

Privacy During UPSC Application Preparation

Your UPSC application photo and signature are sensitive identity documents. Server-based compressors that upload your files to remote storage pose a data exposure risk. CompressKaro processes everything locally in your browser — zero uploads, zero server storage, complete privacy for your UPSC application materials.
