Merge PDF files online — free, private, no upload
To merge PDFs, drop two or more files here, put them in the order you want with the arrow buttons, and press Merge PDFs. The combined file is built inside your browser, so nothing is uploaded and there is no watermark or page limit.
How to do it in 3 steps

- Set the order. Use the ↑ and ↓ buttons, remove any file with ✕.
- Merge and download. Press Merge PDFs and save the combined document.
About this tool
Merging is the most common PDF task: contracts and their appendices, invoices for one month, scanned pages from different sessions, or application forms with supporting documents. This tool copies every page of every file, in your order, into one new PDF and keeps the original page size, text and images untouched.
Because the work happens locally in your browser, confidential documents never reach a server — important for legal, medical and financial files. For heavier work such as reordering individual pages with thumbnails, editing text or redacting, use the free Gold PDF desktop editor for Windows.
Why use it
- Files are processed on your device — nothing is uploaded.
- No watermark, no page limit, no account.
- Original quality is kept: pages are copied, not re-compressed.
- Works on Windows, Mac, Linux, Android and iPhone browsers.
Questions
Is it safe to merge confidential PDFs here?
Yes. The merge runs entirely inside your browser tab. Your files are not sent to any server, so nobody else can see them.
Is there a file size or page limit?
There is no fixed limit. The practical limit is your device memory; most computers handle hundreds of pages easily.
Will merging reduce quality?
No. Pages are copied as they are, so text stays selectable and images keep their original quality.
Can I merge password-protected PDFs?
Remove the password first with the Unlock PDF tool, then merge.
