For scholarship and entrance exam applications

Portals such as the NSP (National Scholarship Portal), CUET (Common University Entrance Test), and state scholarship systems often have strict upload limits for marksheets, income certificates, Aadhaar records, and supporting documents. Compressing your PDF to 150KB helps make uploads smoother and easier to manage.

Services linked to the EPFO (Employees' Provident Fund Organisation), Employees' State Insurance Corporation (ESIC), and pension portals commonly require compact files for KYC documents, passbooks, identity proofs, and claim forms. A smaller PDF is easier to upload and share, especially when completing forms on mobile devices.

Whether you are uploading PAN cards, address proofs, bank documents, or policy paperwork, keeping your PDF compact and lightweight can help make online submissions quicker and more reliable across insurance providers such as LIC (Life Insurance Corporation of India) and other financial service portals.
