Your Files Never Leave Your Device
We use advanced WebAssembly technology to process everything right here in your browser. No uploads. No cloud storage. No privacy risks.
How It Works
Select File
When you select a file, the browser reads it into memory. It is NOT sent to any server.
Local Processing
Our conversion engine (WebAssembly) runs directly on your computer's CPU to transform the data.
Instant Save
The new file is generated instantly and saved to your device. Zero network latency.
Don't Believe Us? Try the "Offline Test"
Load this website, then turn off your WiFi/Internet. You will see that the converter still works perfectly. That's because the code is already running on your machine.
The Technology
We leverage modern browser capabilities including WebAssembly (WASM),Web Workers, and OffscreenCanvas to bring desktop-class performance to the web. This architecture ensures that sensitive documents like contracts, personal photos, and financial data are completely safe.
