Official Photo & Signature Specifications for Government Examinations (2025 - 2026)
Almost every major government recruiting organization across India enforces strict technical criteria for digital passport photographs and scanned signatures. Submitting a file that is even 1 KB above the maximum ceiling or 1 KB below the minimum floor results in immediate portal error alerts like "File size exceeds permitted limits" or "Invalid image dimensions".

How Our Binary Search Algorithm Compresses to Exact KB Without Blur
Traditional online compressors merely decrease quality linearly, frequently resulting in jagged pixelation or files that undershoot by too much (e.g. dropping a 500 KB image straight to 8 KB, which looks unreadable).
RajStudy's Image Resizer Engine utilizes a 7-step recursive Binary Search Algorithm coupled with the HTML5 Canvas API. When you select a target size (e.g., 50 KB), our engine evaluates multiple quality steps in milliseconds within your browser to pinpoint the exact highest fidelity level that keeps the file under 50,000 bytes. This preserves maximum sharpness in facial features, date stamps, and signature pen strokes.
Step-by-Step Guide: How to Resize Photo for SSC & Govt Portals
- Select or Drop Your Image: Drag your photo or signature into the box above, or tap to choose from your gallery or desktop files.
- Choose an Exam Preset: Click on one of our preset chips (e.g. SSC Photo or SSC Signature). The tool automatically configures the ideal target file size and pixel dimensions.
- Fine-Tune if Needed: Use the target size slider to set any specific number between 10 KB and 300 KB. Adjust width and height if your state recruitment portal specifies custom dimensions.
- Inspect and Download: Compare the original photo with the optimized version in the live preview arena. Once satisfied with clarity and file size, click Download Compressed Photo. Your image is immediately saved in standard JPG format.
Guidelines for New SSC Portal (ssc.gov.in) Live Photo & Signature Uploads
The Staff Selection Commission has introduced updated application guidelines for CGL, CHSL, MTS, and Stenographer exams:
- Live Webcam Photograph: In recent notifications, SSC requires candidates to capture a live photograph using a webcam or mobile camera. Ensure your face is centered, eyes open, background is plain white or light, and lighting is uniform across your face without deep shadows or tinted glasses.
- Scanned Signature Requirement: Signatures must still be uploaded as an image file. The signature must be signed with a black or dark blue ink pen on plain white paper within a rectangular box. It must be strictly between 10 KB and 20 KB with dimensions approximately 280 × 120 pixels (4.0 cm × 2.0 cm).
- No Capital Letter Signatures: Applications with signatures written in ALL CAPITAL (BLOCK) LETTERS are summarily rejected across SSC, IBPS, and Railway portals. Always use natural cursive/running hand.
Troubleshooting Common Photo Rejection Errors on Sarkari Portals
- "File size exceeds permitted limits": Select our preset or adjust the target slider to 45 KB (for 50 KB ceiling) or 18 KB (for 20 KB ceiling). Giving a slight buffer prevents portal rejection caused by minor byte-rounding differences.
- "Invalid image dimensions or aspect ratio": Ensure your crop matches the required ratio. Passport photos should follow a 3.5:4.5 vertical ratio (width:height), while signatures follow a 7:3 horizontal ratio.
- "Image is not in JPG/JPEG format": Many modern smartphones save photos in HEIC or PNG. Our tool automatically converts any uploaded PNG, WebP, or JPG into strict standard JPEG format upon download.
100% In-Browser Privacy Protection Guarantee
Uploading passport photographs and signatures to third-party web servers is an identity theft and privacy risk. On RajStudy, the entire conversion and resizing routine executes completely inside your browser client memory. No image data is transmitted to our server or any remote database, ensuring your confidential personal application data remains 100% private and protected.
