About this tool

This tool combines multiple PDF files into a single document by copying each page directly, so formatting, fonts, and images are preserved exactly as they appeared in the originals. The merge runs locally in your browser, which means it also works with confidential documents you wouldn't want uploaded to a third-party server.

Add your files, then use the up and down arrows to set the exact order pages should appear in the final document — the first file in the list becomes the first pages of the merged PDF, and so on. There's no limit on how many files you can combine in one go.

Common uses include combining scanned pages into one document, assembling a multi-part report or application from separate PDFs, or merging invoices and receipts into a single file for record-keeping.

Frequently asked questions

How many PDFs can I merge at once?
There's no hard limit — you can combine as many PDF files as your browser's memory allows, which is typically dozens of files.
Will merging affect the quality of my PDFs?
No. Pages are copied directly from the source files, so text, images, and formatting stay exactly as they were.
Can I control the order of the merged pages?
Yes — reorder files with the up/down arrows before merging. The final PDF follows that exact order.
Are my files uploaded to a server?
No, the entire merge happens in your browser using JavaScript. Your files never leave your device.
