ToolHubMerge PDF files
Combine PDFs in the order you want, right in your browser. Your files never leave your device.
Are my files uploaded anywhere?
No. The merge runs entirely in your browser using pdf-lib. Nothing is sent to a server, and closing the tab removes everything.
Does the output keep my order?
Yes. Use the up and down arrows to arrange the files, and the merged PDF follows that exact order.
Is there a size limit?
Only your device's memory. Very large sets of PDFs may take a few seconds, but there is no artificial limit and no account.
