What happens to your files

This tool runs entirely in your browser. The file you choose is read into memory, processed on your device, and offered back as a download. Nothing is uploaded and nothing is kept once you leave the page.

There is no account, no email, no watermark and no daily limit. Come back whenever you need it.

Frequently asked questions

Are my files uploaded to a server?
No. The merge happens locally in your browser using WebAssembly and JavaScript. Your PDFs never leave your device.
Is there a limit on the number of files?
There is no fixed limit. Very large documents are only constrained by your device's available memory.
