Why compress your PDFs for SSC GD Constable (NIA / SSF)?
During the 2026 SSC GD Constable (NIA / SSF) online registration, the Staff Selection Commission (SSC) requires candidates to upload educational mark sheets and reservation certificates strictly in PDF format. The portal will block any upload that exceeds the strict 300KB maximum file size. Additionally, if your degree spans multiple semesters, you must merge all pages into a single PDF document before uploading. Our free SSC PDF toolkit performs both the merging and the heavy compression locally in your browser, ensuring your documents remain readable while securely passing the upload constraints.
