Your file never leaves this tab.

Everything runs in JavaScript (and WebAssembly) on your device. We can't see your PDF, and neither can our servers — because your file never touches them.

FAQ.

Common questions about merge pdf. Something else on your mind? Ask us.

Is it really free?

Yes. Free forever. No sign-up. No credit card. No trial.

Do you upload my files?

Never. Everything runs locally in your browser using JavaScript and WebAssembly.

What is the max file size?

Only limited by your browser’s memory. Most laptops handle 100MB+ with ease; very large files may be slower.

Does it work offline?

Once the page and its tool script have loaded, yes — processing runs entirely client-side.
