Overview
Government websites often apply strict PDF upload limits. The goal is not simply to make the smallest file; the document must remain clear enough for review and verification.
Why this matters
An unreadable compressed document may be rejected even when it meets the required file size.
Start with a clean source document
Before compressing, remove blank pages, duplicate scans, unnecessary colour photos, and pages that the form does not request. A clean source PDF compresses more effectively.
Use properly cropped scans with a plain background. Dark camera photos and excessive empty space make a document larger than necessary.
Use the right compression level
Start with Recommended Compression for most certificates, forms, identity documents, and marksheets. It normally provides a useful balance between size and readability.
Use stronger compression only when the portal limit requires it. Always inspect names, dates, signatures, photographs, seals, and QR codes afterwards.
Confirm before final submission
Check the exact size shown by your device and compare it with the portal limit. If the portal says under 1 MB, leave a small safety margin instead of making a file exactly 1 MB.
Keep both the original and compressed copies until your application has been accepted.
