Merge PDF
Combine contracts, scans, invoices, or chapters into one PDF — in exactly the order you choose. Nothing is re-compressed, so every page stays crisp.
Private by design: This tool merges documents locally using an in-browser PDF library. Your files are not uploaded to a server, and nothing is stored or logged.
How to merge PDF files
Drop two or more PDFs onto the upload area.
Arrange them with the up/down arrows — the list order becomes the final page order.
Click Merge PDFs, then download the combined document.
Good to know
All pages from each document are included, in list order.
Pages are copied without re-compression, so quality and page sizes are preserved exactly.
Password-protected PDFs need their password removed before merging.
Frequently asked questions
Can I change the order of the documents?
Yes — use the up/down arrows next to each file before merging. The file at the top comes first in the merged PDF.
Is there a limit on file count or size?
No fixed limit — merging happens on your device, so capacity depends on your browser's memory. Dozens of typical documents merge without trouble.
Will page sizes and orientations be preserved?
Yes. Each page keeps its own dimensions and rotation, so mixing A4, Letter, portrait, and landscape documents works fine.
Are my documents uploaded to a server?
No. Merging happens entirely in your browser — your documents never leave your device.
