Your Privacy is our Superpower
At CosmiPDF, we don't just "protect" your data—we never even see it.
How it Works (The Technical Part)
Most PDF websites work by uploading your file to a server, processing it, and then letting you download it. This means your private documents live on someone else's computer for at least a few minutes.
Local Loading
When you "upload" a file, it's actually just loaded into your browser's memory. It never leaves your network.
WASM Processing
We use WebAssembly (WASM) and high-performance JavaScript libraries to perform complex PDF operations right inside your browser tab.
Instant Output
The resulting PDF is generated locally and offered as a download. No servers were involved in the making of your document.
