Navigating narrow 10–12 day JoSAA counseling windows.
During JoSAA and CSAB seat allotment rounds, candidates receive an extremely narrow 2-to-3 day window per round to accept seats, pay fees, and upload verified certificates.
Uploading an invalid file format or exceeding the 300 KB ceiling for Category/PwD certificates will cause query raises by verifying officers at reporting centers (RCs). If queries are not resolved within 24 hours, seat allocations risk automatic cancellation.
Merging multiple documents into a single PDF before compression.
Certain counseling rounds require combining multiple term marksheets or multiple pages of a medical certificate into a single PDF.
Ensure your merged document is under 300 KB so the portal system accepts your upload instantly without error flags.
Your files stay on your device.
Your JEE Rank Cards, Category Certificates, and Marksheets remain 100% private in browser RAM.
