Merge PDF

Combine multiple PDF files into one, with reorderable pages. Everything runs in your browser—your files never leave your device.

FAQ

Are my uploaded PDFs sent to a server?

No. All merging happens entirely in your browser and files never leave your device.

Can I change the merge order?

Yes. Use the up/down arrows in the file list to reorder before merging.

Is there a file limit?

There is no fixed limit, but since processing runs in your browser, very many or very large files may be slower depending on your device.
