Merge PDF files
Combine several PDFs into one document in the order you want.
Add two or more PDF files, put them in the right order and merge.
Private by design: this tool works entirely in your browser. Your files are never uploaded to our server. Free, no sign-up, no watermark.
How to use
- Add two or more PDF files.
- Drag the files (or use the arrows) to set the order.
- Press “Merge PDF”.
- Download the combined PDF.
The tool copies all pages, including text, images, links and fonts, into one new PDF without re-compressing them, so the quality stays exactly the same.
Frequently asked questions
Is there a limit on the number of files?
No fixed limit. Merging happens in your browser, so the practical limit is your device memory — hundreds of pages are fine on a normal computer or phone.
Are my PDFs uploaded?
No. Files are merged locally in your browser and never sent to a server.
Can I merge password-protected PDFs?
No. Remove the password first (open it in a PDF reader and save an unprotected copy), then merge.
Will the quality change?
No. Pages are copied as they are, without re-compressing images or text.
