Why Do Government Portals Have File Size Limits?
Indian government portals typically serve crores of users simultaneously. To keep their servers running smoothly and ensure fast load times for everyone, they impose strict file size limits on uploaded documents. This is standard practice globally, but the limits on Indian government sites tend to be on the stricter side — often between 100KB and 1MB per file.
Unfortunately, documents scanned at home or on a printer often come out much larger than these limits — sometimes 5MB or more for a single page. That's where a PDF compressor comes in.

3 Select a Compression Level
Choose how much to compress:
🟢 Low — Slight reduction, best quality. Use for portals with limits above 1MB.
🟡 Medium — Good balance of size and quality. Works for most portals.
🔴 High — Maximum compression. Use when you need under 300–500KB.

UPSC Civil Services Application
UPSC typically requires all document uploads to be under 300KB. Use the High compression setting. If you're uploading a photograph, it should be a separate JPG file (not embedded in a PDF). For certificates and mark sheets, scan at 150 DPI instead of 300 DPI to get a smaller starting file.
SSC Online Forms
SSC portals generally accept files up to 500KB. Use Medium compression for most documents. Make sure the text in your certificates is still clearly readable after compression — the exam board needs to verify the information.
Passport Seva Portal
The Passport Seva portal accepts documents up to 1MB each, which is more lenient than most. Medium compression should be sufficient. Pay special attention to address proof documents — the full address must remain legible.
College Admissions (DU, JNU, State Universities)
University portals vary widely. Some accept up to 2MB, others only 200KB. When in doubt, compress to under 500KB to be safe — this works across almost all Indian university admission portals without sacrificing readability.
What If My PDF Is Still Too Large?
If your file is still over the limit after high compression, try these additional steps:
1. Split the document — Use the Split PDF tool to upload only the specific pages required by the portal, rather than the entire document.
2. Scan at lower DPI — If you're scanning a physical document, try 150 DPI instead of 300 DPI. The file will be significantly smaller with no noticeable quality difference for text documents.
3. Convert to JPG — Some portals accept JPG images instead of PDFs. Use the PDF to JPG tool to convert individual pages, which may be smaller in file size.
4. Remove blank pages — Use the Split PDF tool in "Custom Range" mode to create a new PDF that includes only the necessary pages, excluding any blank pages.
Is It Safe to Compress Official Documents Online?
Using PDF Vault is completely safe for official documents. Unlike many online tools that upload your files to their servers, PDF Vault processes everything locally in your browser. Your Aadhaar card, marksheets, certificates, and other sensitive documents never leave your device. There is no risk of your files being stored, accessed, or leaked.
