About this tool

Combine several PDF files into a single document, reorder them by drag-free up/down controls, and download the result. Your files are merged locally and never uploaded.

  • Files are processed on your device — nothing is uploaded.
  • No account, no watermark, no daily limits.
  • Works offline once the page has loaded.

Frequently asked questions

Are my PDFs uploaded to a server?
No. The files are merged locally in your browser. Nothing is uploaded, which keeps sensitive documents private.
Can I change the order of the files?
Yes. Use the up and down arrows to arrange the PDFs. They are combined top-to-bottom in the order shown.
Is there a limit on how many PDFs I can merge?
No fixed limit. Since merging runs on your device, the only constraint is your available memory.
What about password-protected PDFs?
Unencrypted PDFs work best. Some protected files may fail to load; remove the password first if merging fails.
