Frequently asked questions
Passport Seva rejected my PDF — what's the limit?
Passport Seva's document upload limit is 300KB per file. Scanned PDFs from phone scanner apps like CamScanner or Adobe Scan often produce 1–5MB files. Use this tool to compress to under 300KB instantly before uploading. Ensure the document shows clearly with no dark edges or shadows for best results.
Can a 2-page Aadhaar PDF be compressed to 300KB?
Yes — a 2-page Aadhaar card PDF (which is usually 500KB–2MB) compresses easily to under 300KB. Both pages remain fully readable including the QR code, name, DOB, and address.
Does compression affect QR codes in Aadhaar PDFs?
At 300KB compression levels the QR code remains scannable in most cases. However, if the portal requires QR code scanning (not just visual verification), compress at a higher quality setting — use 500KB or 1MB if the portal allows it.
