#1. Official Photo & Signature Specifications for Competitive Exams

Every recruitment commission in India—including SSC, UPSC, Railway Recruitment Boards (RRB), IBPS, and State Police Recruitment Boards—enforces stringent digital image parameters for candidate photographs and specimen signatures.

Uploading a file with incorrect file size (e.g., 55 KB instead of max 50 KB), wrong aspect ratio, or blurred pixels is the #1 reason why lakhs of online application forms are rejected at the scrutiny stage without refund of application fee.

Most recruitment portals require candidate photographs between 20 KB to 50 KB in JPEG/JPG format with dimensions of 3.5 cm (width) x 4.5 cm (height). Specimen signatures generally require 10 KB to 20 KB with dimensions of 4.0 cm x 2.0 cm.

#2. How to Resize Photo to 20–50 KB on Mobile Without Quality Loss

Aspirants can resize, crop, and compress their passport photos directly from their smartphone in less than 30 seconds using the free browser-based Sarkari Jobs Photo Resizer tool (/tools/image-resizer):

• Step 1: Place your passport photograph on a flat surface in good daylight (avoid direct camera flash or heavy shadows) and click a clear, high-resolution photo with your smartphone camera.
• Step 2: Open the Sarkari Jobs Image Resizer (/tools/image-resizer) in your mobile browser. Tap 'Select Image' and choose your photo from your phone's gallery.
• Step 3: Select your exam preset (e.g., 'SSC CGL / CHSL / MTS', 'UPSC Civil Services', or 'Railway RRB NTPC') from the dropdown. The tool automatically configures the exact aspect ratio (3.5 x 4.5 cm).
• Step 4: Use the compression slider to dial your target file size between 20 KB and 50 KB. The smart canvas algorithm preserves sharp facial features while eliminating redundant metadata.
• Step 5: Tap 'Download Resized Image'. The resulting JPEG file will be strictly compliant and ready for direct upload.

#3. Common Photo Rejection Grounds (Critical Mistakes to Avoid)

Review this essential checklist before submitting your photo to any government commission portal:

• No Caps, Hats or Sunglasses: The candidate's full face, forehead, eyes, nose, and both ears must be clearly visible. Dark or tinted glasses lead to automatic rejection.
• Plain White / Off-White Background: Photographs taken against colorful curtains, outdoor scenery, or textured wallpapers are rejected by AI scrutiny systems on SSC and UPSC portals.
• Frontal Pose with Neutral Expression: The candidate must look straight into the camera lens with both shoulders level. Tilted head, side profiles, or smiling selfie poses are strictly disqualified.
• Recent Photograph (Within Last 3 Months): Do not upload childhood pictures or photos with drastically different facial hair or hairstyles that impede identity verification at the exam center.

#4. Signature Upload Guidelines: Ink Color, Cropping & Dimensions

Signature scanning requires equal care to prevent application rejection:

• Ink Color: Always sign using a black or dark blue ballpoint pen. Gel pens often smudge during scanning, while faint pencils fail contrast thresholds.
• Paper Quality: Sign on unlined, plain white paper (A4 printer paper). Never sign on ruled or lined notebook paper.
• No ALL-CAPS Signatures: Signing in capital block letters (e.g., 'RAJESH KUMAR') is rejected by banking (IBPS/SBI) and central commissions. Use your standard cursive running handwriting.
• Horizontal Framing: Crop tightly around the signature boundaries without excess whitespace. Target a 2:1 width-to-height aspect ratio (4.0 cm width x 2.0 cm height, 10 to 20 KB).
