Merge PDF files without uploading them

Combining PDFs on a website usually means every file is uploaded, joined on a server, then offered back. That is a lot of trust for a packet of invoices or a signed contract.

Merge PDF does the join in the tab. Drop several files, drag to reorder, expand a file to uncheck pages you do not want, then download one PDF.

Steps

1. Add two or more PDFs.
2. Drag the list so the first file is the one that should appear first.
3. Optional: expand a file and click thumbnails to drop pages.
4. Merge, then download.

Need the opposite job? Split PDF extracts pages the same way — still on-device.
