Merge PDF.

Combine several PDFs into a single document — reports, scans, invoices, contracts — in the order you choose. Everything happens in your browser, so confidential documents are never uploaded to a server. Add files, drag them into order, and download one merged PDF.

Drop PDF files (add as many as you like) here, or browse

Files stay on your device — nothing is uploaded.

i. Add the PDF files you want to combine.

ii. Use the up/down arrows to put them in the right order.

iii. Click Merge — the PDFs are stitched together locally with pdf-lib.

iv. Download the single merged PDF. Nothing was uploaded.

Frequently asked questions

Are my PDFs uploaded to a server?

No. Merging happens entirely in your browser. There is no upload endpoint, so even confidential documents stay on your device.

Is there a limit on the number or size of files?

No artificial limit and no watermark. The practical ceiling is your device’s memory, since everything is processed locally.

Can I change the page order?

Yes — reorder the files with the arrows before merging. Pages follow that order.
