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.

What size PDFs can be compressed to 150KB?
