Merge PDF files
Combine several PDFs into one document, in whatever order you like. Bookmarks, internal links and form fields come along.
Your files never leave your browser. Nothing is uploaded, anywhere.

No limit on file count or size — only your computer’s memory.
How it works
- Drop in your PDFs — as many as you like.
- Put them in order by dragging, or with the arrows. For any file you can keep just some of its pages.
- Merge, then download the result. Nothing ever left your computer.
Questions
- Are my files uploaded anywhere?
- No. The merge runs in your browser, on your own machine. Once the page has loaded you can even go offline and it keeps working.
- Is there a limit on size or number of files?
- No. The only limit is your device’s memory; an ordinary laptop merges thousands of pages without trouble.
- Will the quality drop?
- No. Pages are copied exactly as they are, never re-rendered: text stays selectable and images keep their full resolution.
- What if a PDF is protected?
- If it opens without a password but blocks printing or copying, it’s merged straight away. If it needs a password, you’ll be asked for it — it’s only used to open the file here, and never sent anywhere.
