Questions

Will page order be kept?

Yes — the list order is the document order. Use arrows to fix it before merging.

Is there a file limit?

Up to 20 files / ~100 MB total in-browser. Split bigger batches into halves.

Are my files uploaded?

No. Merging runs with pdf-lib on your device. Verify in DevTools → Network.
