PDF Merger
Merge every page from two or more PDFs into merged.pdf in the user-defined file order.
How to use
- Add multiple PDFs, arrange the file list, then choose Merge in this order and download the result.
Capabilities and scope
The dedicated merger shows each file's page count, allows drag or up/down file ordering, and uses pdf-lib copyPages to append all pages.
How it works
A new PDFDocument receives every page from source.getPageIndices() for each input file in list order.
Example
Putting a 2-page A.pdf before a 3-page B.pdf creates a 5-page result with A first.
Useful for
- Combine several scanned or reference PDFs locally in the browser
Before you use it
- Unreadable/protected PDFs can fail, and bookmarks, forms, attachments, or other advanced document structures are not guaranteed to survive identically.
