Frequently asked questions
Is it free to merge PDF files?
Yes. Merging PDFs here is free, with no sign-up, no email and no watermark on the result.
Are my files uploaded anywhere?
No. The merge happens entirely in your browser on your own device, so your documents never leave your computer.
Is there a limit on the number of PDFs?
There is no fixed limit. Very large jobs depend on your device's memory, since the work runs locally rather than on a server.
Can I reorder the files before merging?
Yes, drag them into any order first. For page-level editing across documents, the Core PDF desktop app gives you full control.
