Frequently asked questions

Is the document uploaded?

No. This ordinary tool is designed to process the selected file in browser memory and does not intentionally send document content to our application server.

How many PDFs can I merge?

The practical limit depends on total file size, page count, and device memory. Desktop browsers are more reliable for large jobs.
