Merge, split, compress, and convert PDFs right here in your browser. Nothing is uploaded, ever.
Here's the proof, not just our word
0bytes sent to any server, ever
This number updates live while you use the tools on this page. Add a file, merge it, compress it, whatever you like. Watch it stay at zero.
That's because your file is processed entirely by your own device.
Your phone or computer does the work using the same kind of code that
runs apps on your phone, it just happens to run inside your browser tab.
Nothing is ever sent anywhere, so there's nothing for us, or anyone
else, to see.
I want to check this myself (technical)
Open your browser's developer tools (F12, or right-click → Inspect)
Click the "Network" tab
Upload a file and run any tool on this page
You'll see no requests carrying your file data, ever
The full source code is also public, so anyone can check it line by line.
