PDF Requirements for Indian Government Portals — Size Limits and Format Guide
2026-06-03 5 min read
GST portal, MCA21, income tax portal — each has strict PDF size limits. Here is how to get scanned documents under 1-2 MB without losing readability.
Indian government portals have specific PDF requirements that trip people up regularly. Wrong file size, wrong format, unreadable scan quality. Understanding these requirements saves hours of frustration during tax season, company filings, and regulatory submissions.
Common file size limits on Indian government portals
- GST portal (gst.gov.in): 5 MB per attachment for most uploads
- MCA21 (mca.gov.in): 10 MB per document for company filings
- Income tax portal: 2 MB for most supporting documents
- EPFO portal: 1 MB limit for provident fund documents
Getting documents under portal size limits
- Scan at 150 DPI in grayscale for text-only documents. Color triples file size for no benefit.
- Upload to the PDF Compressor.
- Use eBook preset as first pass. Check readability.
- If still too large, use Screen preset (72 DPI).
- Verify final file size before uploading to the portal.
Combining documents for portal submissions
For attaching multiple documents as a single file, the PDF Merger combines them in your browser without uploading to third-party servers. This matters when documents contain your GSTIN, bank details, or employee information.
