How it works

Can I set the order?

Yes — use the ▲ / ▼ buttons to arrange the files. They're merged top-to-bottom in the order shown.

Is there a file-count or size limit?

No hard limit — it's bounded only by your device's memory, since everything runs locally. Very large scanned PDFs use more RAM.

Are my documents uploaded?

No. The merge happens entirely in your browser — your PDFs never leave your device, so it's fully private and works offline once the page has loaded.
