Merge PDF files into one
Add your PDFs, put them in order and download a single combined file. Everything happens on your device.
Files stay in this browser tab. Close the page and they are gone.
How it works
- Add two or more PDF files, or drop them onto the page.
- Use the arrows to put them in the order you want.
- Press “Merge PDF” and save the combined file.
Questions
Will the quality change?
No. Pages are copied exactly as they are — text stays selectable and images are not recompressed.
Can I merge a password-protected PDF?
Not directly. Open it with its password and save a copy without protection first, then merge that copy.
Are my files uploaded anywhere?
No. The tool runs entirely in your browser, so your files never leave your device and nothing is kept after you close the page. You can check it yourself: once the page has loaded, turn on airplane mode — the tool keeps working.
Is it free? Is there a file limit?
Yes, it is free, with no sign-up and no watermark. There is no upload limit because nothing is uploaded; very large files are limited only by your device’s memory.
