Document Specs Checker
Verify whether your exam photo, signature, or document meets upload specifications — file size, container format, and pixel dimensions.

Document Verification Tri-Metric Audit
Upload servers reject files instantly if any of the three technical compliance criteria fail:
Verified = FormatValid && (MinKB ≤ FileSizeKB ≤ MaxKB) && ProportionsValid
ProportionsValid = (MinW ≤ Width ≤ MaxW) && (MinH ≤ Height ≤ MaxH) && |Ratio - TargetRatio| ≤ Tolerance
Passport Photo Target: 3.5cm / 4.5cm ≈ 0.778 (±5% tolerance)
Upload & Resizing Mistakes
Simply renaming a .png file extension to .jpg without converting.Changing the file extension does not alter the underlying binary container format. Government upload servers detect MIME types and reject renamed files as corrupt.
Over-compressing images below the minimum file size limit.Portals often specify both a minimum (e.g. 10 KB or 20 KB) and maximum file size. Using extreme compression software can make your image fall below the minimum threshold.
Distorting proportions rather than cropping to the required aspect ratio.Stretching or squishing an image to meet pixel dimension constraints results in distorted facial features or illegible signatures, risking disqualification during document verification.
Biometric & Scanning Guidelines
- SSC Guidelines for Scanning and Upload of Photograph and Signature
- UPSC Instruction for Uploading Scanned Images of Photo & Signature
- IBPS Guidelines for Scanning Photograph, Signature, and Thumb Impression
- ISO/IEC 19794-5 Biometric Data Interchange Formats for Face Recognition
The Document Upload Verification Framework
Online recruitment portals automatically reject non-conforming uploads with cryptic error codes. Pre-validate byte boundaries and aspect proportions before submitting.

Frequently Asked Questions
It checks up to five properties of your uploaded document's metadata against the exam's requirements: file size (minimum and maximum in KB), file format (JPG, PNG, PDF, etc.), width in pixels, height in pixels, and aspect ratio. It does not read or analyse the content of the image — only its technical properties.
