How this tool works
The selected PDFs are parsed and copied into a new document in the order shown in the queue, entirely inside a browser worker.
- Choose at least two PDF files.
- Use the arrow controls to arrange their order.
- Merge and download one new PDF containing the copied pages.
Processing stays inside a disposable browser worker. Canceling or leaving the page terminates that worker and releases its memory.
