Merge PDF files
Join several PDFs into a single document in seconds. Reorder the files before merging, then download the result. Merging happens right in your browser: no file is ever uploaded.
Your files stay on your device — nothing is uploaded.
How to
- Drop your PDF files into the box or click to select them.
- Use the arrows to set the final order.
- Click “Merge PDFs” and download your document.
Frequently asked questions
Are my files uploaded to a server?
No. Merging runs entirely in your browser using JavaScript. Your documents never leave your computer or phone.
How many PDFs can I merge?
There is no fixed limit. The only constraint is your device’s memory: dozens of regular documents merge without trouble.
Is the quality preserved?
Yes. Pages are copied as-is with no recompression, so text, images and links keep their original quality.
Can I merge password-protected PDFs?
Encrypted PDFs must be unlocked first. The tool will tell you if a file is protected.
