How to merge PDF files
- Add your PDFs. Drop the files onto the box above, or click to browse. Add two or more.
- Set the order. Drag the file cards to arrange them. The top file comes first in the merged document.
- Merge. Click Merge PDF and the combined file downloads straight to your device.
Why it's private by design
Most online PDF mergers upload your files to a server. This one doesn't. The whole merge runs in your browser using JavaScript, so your documents never travel across the internet — a sensible choice for contracts, statements, or anything confidential.
What gets preserved
Pages are copied across exactly as they are, keeping their original size and content. The files are joined in the order you set, one after another, into a single continuous PDF.
Common questions
Are my files uploaded anywhere?
No. Everything happens locally in your browser. Nothing is sent to a server, so it works even offline once the page has loaded.
How many files can I merge?
There's no hard limit. Because the work runs on your own device, the only real ceiling is your computer's memory.
Can I reorder the files before merging?
Yes — drag the cards into any order. The sequence shown is exactly the order they'll appear in the final PDF.
Does it add a watermark or cost anything?
Neither. It's free, needs no sign-up, and adds no watermark.
