Is there a limit on the number of PDFs?

You can merge as many PDFs as your browser can comfortably hold in memory — typically 30+ files at once.

Will the original formatting be preserved?

Yes. Pages are copied byte-for-byte from the source files, so fonts, images, and layout stay intact.

No. Merging happens entirely in your browser, so files never leave your device.
