Many PDFs in, one PDF out.
Add your PDF files, put them in the right order, and combine them into a single document — with text and quality intact. Everything happens in your browser, so even sensitive files never leave your device.
Add PDFs
Drop in two or more PDF files — they're read locally, never uploaded.
Set the order
Move files up or down so the merged document flows the way you want.
Merge & download
Combine them into one PDF and download it in a click.
Are my PDFs uploaded to a server?
No. The files are combined entirely in your browser using pdf-lib — nothing is uploaded, so even confidential documents stay private.
Is there a file-size or file-count limit?
There's no artificial limit — you can merge as many PDFs as your browser's memory can handle. Very large files just take a moment longer.
Can I choose the order of the files?
Yes. After adding your PDFs, use the up/down controls to arrange them; the merged document follows that exact order.
Does merging change the quality?
No. Pages are copied as-is into a new document, so text stays selectable and images keep their original quality.
Is it free?
Yes — completely free, no sign-up and no watermark.
