Merge PDFs. Stitch deal packets in one tab.
Drop two or more PDFs, drag the pages into the order you need, rotate the odd one, and ship the merged file straight from memory. Every byte stays in this tab — no upload, no recompression, no waiting on a stranger’s server.

The tool
Drop it in, reorder the pages, grab the merged file.
The browser opens each PDF locally with the File API and renders a single combined thumbnail grid for every page across every source. Drag to reorder, rotate where it reads better, and remove an extra cover. The merge runs in-memory.
How it works
Three steps. No upload stage.
The flow mirrors the rest of PDF5. Familiar enough to hand to a colleague without a tutorial.
- STEP 01
Drop your PDFs
Drag-and-drop a stack of files or pick them from the picker. The browser opens each one locally with the File API — every page across every source turns into a thumbnail in a single combined grid.
- STEP 02
Reorder, rotate, remove
Drag thumbnails to set the page order. Rotate odd pages by 90° with one click. Drop the pages that don’t belong — the source list mirrors the page list so the box stays tidy.
- STEP 03
Download the merge
Your browser re-extracts the pages with PDF-lib into one document and hands you the merged file straight from memory. No recompression, no upload, no waiting on a server.
