Official Document Specifications for Indian Govt Exams (SSC CGL, UPSC, IBPS, NEET 2026)

Thousands of Indian examination candidates face application rejections or last-minute panic during online form submission on portals like SSC, UPSC, and IBPS. The primary culprits are strict server-side validation checks:

• File Size Violations: Portals strictly reject photos exceeding 50KB or falling below 20KB.
• Signature Dimension Errors: Signatures must be between 10KB and 20KB with precise aspect ratios (typically 3:1 or 2:1).
• Low Contrast & Artifacts: Smartphone photos of handwritten signatures on lined paper frequently fail OCR verification.
• Multi-Page Certificate Limits: PDFs must be formatted to standard A4 size under 200KB–300KB.

The Staff Selection Commission (SSC) enforces strict digital guidelines for CGL, CHSL, and MTS exams:

• Photograph: 20KB to 50KB in JPEG/JPG format. Dimensions must be approximately 3.5 cm (width) × 4.5 cm (height). The photo must be recently taken without cap, spectacles, or heavy shadows, with 80% face coverage.
• Signature: 10KB to 20KB in JPEG/JPG format. Dimensions must be approximately 4.0 cm (width) × 2.0 cm (height). Applications with blurred signatures or blue ink on non-white paper are systematically rejected.

The Union Public Service Commission (UPSC) requires candidates to upload documents meeting these exact criteria:

• Photo: 20KB to 300KB (minimum 350 × 350 pixels; maximum 1000 × 1000 pixels). The candidate's name and date of photo must be clearly printed at the bottom of the photograph.
• Signature: 20KB to 300KB (minimum 350 × 350 pixels).
• Photo ID Card: PDF format only, size between 20KB and 300KB.

• IBPS (PO, Clerk, SO): Photograph must be 20KB–50KB (200 × 230 pixels). Signature must be 10KB–20KB (140 × 60 pixels) in black ink only. Left thumb impression must be 20KB–50KB in black or blue ink.
• NTA NEET: Passport photograph must be 10KB–200KB. Postcard size photograph (4" × 6") must be 10KB–200KB. Signature must be 4KB–30KB.

Millions of students visit local cyber cafes or use free online image compression websites to resize their documents. Many of these commercial websites upload your Aadhaar card, caste certificates, signatures, and personal photos to unsecured third-party servers.
