Are my documents uploaded to a server?

No. The files are read from disk into the page, merged there, and written back to your downloads folder. Nothing is transmitted.

Can I change the page order?

Pages follow the order of the files you select. Reorder the files before merging, or split and re-merge if you need a different arrangement.

Is there a page limit?

The limit is your browser memory rather than a server quota. Very large scanned documents can be slow on a phone.

PDF Merge

Select the PDFs you want to combine, confirm the order, and download a single merged file. Because the merge runs in your browser, the documents are never uploaded — which is the difference that matters for contracts, invoices, and medical records.
