How to verify nothing uploads
You don't have to take our word for it. Two checks, each under a minute:
- Watch the network. Open DevTools (F12, or Cmd + Option + I on macOS), switch to the Network tab, then run the tool. You'll see requests for the page, scripts, ads, and analytics — none of them carrying your files.
- Go offline. Run the tool once so your browser has all the code, then turn on airplane mode or switch off Wi-Fi and run it again. It still works, because the processing happens on your device.
Ads and anonymous analytics make their own requests and never include your files. See our privacy policy for the full list.
FAQ
How do I merge PDFs without sending files to a server?
Open this page, select or drop your PDF files, arrange them in the order you want, and click Merge PDF. Processing runs locally in your browser — nothing is sent to a server.
Can I combine multiple PDFs into one file?
Yes. Select multiple PDF files and the tool combines them into a single document, preserving the order you choose.
Are my PDF files sent to a server?
No. All merging happens in your browser on your device. Your PDFs never leave your device, and no account is required.
Can this merge password-protected PDFs?
No. Password-protected or encrypted PDFs cannot be merged. Remove the password with another tool first, then merge here.
Does the order of selected PDFs matter?
Yes. Pages from each PDF are added in the order shown in the list. Use the up and down controls to reorder files before merging.
