Staff Selection Commission (SSC) Document Upload Rules

With the introduction of the Staff Selection Commission's new One Time Registration (OTR) system, the way candidates upload documents for exams like CGL, CHSL, MTS, and GD Constable has become much more streamlined. However, the strict file size limits remain firmly in place.

Navigating the SSC OTR Portal Limits

While photographs and signatures must be uploaded as small JPGs, the SSC portal frequently requires PDF uploads for supporting documentation, particularly during the Detailed Option Form submission or document verification stages. These PDFs generally need to be compressed to under 1MB, and often specifically under 500KB or 300KB depending on the specific notice.

  • Ex-Servicemen Discharge Books: Must be uploaded as a clear, compressed PDF.
  • Experience Certificates: For specific posts requiring prior work history.
  • Educational Equivalency Certificates: For candidates holding degrees not explicitly listed in the standard dropdown menus.

Maintaining Quality During Compression

The biggest challenge candidates face is that compressing a PDF too much can render the text unreadable. The SSC explicitly states that blurry or illegible documents will lead to the cancellation of your candidature. Our PDF Compressor uses advanced, local browser algorithms to strip away unnecessary background data while preserving the high-contrast pixels of your text. This ensures your certificates pass both the automated file-size check and the human readability check.

Fast, Secure, and Mobile-Friendly

Millions of SSC candidates apply using their smartphones. Because PDF Vault operates entirely via your mobile browser's JavaScript engine, you do not need to download heavy apps or wait in server queues. You can photograph your certificate, convert it to PDF, compress it to the exact SSC requirement, and upload it to the OTR portal-all from your phone in under two minutes.
