When do you need to compress a PDF to 1MB
For government verification uploads
A 1MB PDF helps keep birth certificates, address proofs, land ownership records, and supporting verification documents ready for uploads on Passport Seva and PMAY-G portals with smoother approvals, verification checks, submission handling, and document processing workflows.
For research and fellowship applications
Many portals such as UGC NET, ICMR, and DST-INSPIRE require marksheets, recommendation letters, research summaries, and supporting certificates to stay within upload limits. Compressing files to 1MB helps maintain detailed formatting while ensuring smoother submissions and verification processes.
