About this tool
Merge PDF combines several PDFs — or a mix of documents — into one file, in the exact order you choose. It's the fastest way to join separate chapters, invoices, scanned pages, or signed contracts into a single document that's easy to send and print. Drag the files to reorder them before you combine.
Everything runs in your browser, so your documents never leave your device — a real difference from tools that upload every file to a server. There's no page limit, no watermark, and no sign-up; the merged PDF keeps the original quality of each source file.

Frequently asked questions
How do I combine multiple PDFs into one?
Add all your PDF files, drag them into the order you want, and click merge. The combined PDF downloads in seconds.
Can I change the order of pages before merging?
Yes. Reorder the files by dragging them; the final document follows that order top to bottom.
Is there a limit on how many PDFs I can merge?
No — combine as many files as you need. There are no page caps, watermarks, or daily limits.
Do my files get uploaded to a server?
No. Merge PDF runs entirely in your browser, so your documents never leave your device.
Will merging reduce the quality of my PDFs?
No. Merging simply joins the files; each page keeps its original resolution and text.
