One upload box, five documents
Application portals — CBSE and UP board 2026, NEET, JEE Mains, CUET, CTET, SSC CGL / CHSL / GD / MTS, RRB NTPC and Group D, IBPS, SBI PO, UPSC, NDA, GATE, IGNOU, AIBE and BSTC — often provide a single upload field for "all supporting documents". Your documents live in five separate PDFs. This page turns them into one, in the order you choose, without touching the quality: pages are copied, not re-scanned, so text stays sharp and selectable.
Nothing is uploaded
The merge runs in your browser using the pdf-lib engine. Marksheets and ID documents never leave your device.
