Is there a file size or page limit?

There is no fixed limit — the tool runs in your browser, so it's only bounded by your device's memory. For very large files (500MB+), use a desktop browser.

Do my files get uploaded to a server?

No. Merging happens entirely on your device. Your PDFs never leave your browser.

Can I reorder pages before merging?

You can reorder the whole files. For page-level reordering, use Split PDF first, then merge in the order you want.
