Private by design

Unlike most "merge PDF" sites, this tool never uploads your documents. The merge is performed in your browser with a JavaScript PDF library, so sensitive contracts, statements and scans stay on your device.

You control the order

Add as many PDFs as you like, then drag-free reorder them with the up/down controls before merging. The pages are combined exactly in the order shown.

Frequently asked questions

Are my PDF files uploaded to a server?

No. The merge happens entirely in your browser — your files never leave your device.

How many PDFs can I merge?

There is no fixed limit; you can add as many as you like. Very large documents use more memory since everything runs locally.

Can I choose the order of the files?

Yes. Reorder the files with the up/down controls before merging; pages are combined in the order shown.

Does merging change the pages?

No. Pages are copied as-is into a new document, so their content and quality are preserved.
