Your files never
leave this device.
Other converters upload your tax return, your passport scan, your contract to a server you have never heard of. damnfiles compiles the same engines to WebAssembly and runs them inside your own browser tab. There is no upload endpoint to breach.
- Zero bytes of file data cross the network
- Verifiable — open DevTools, watch the Network tab stay empty
- Installs as an app and keeps working on a plane

Correct. Every tool on damnfiles runs as WebAssembly inside your own browser tab. Open your browser DevTools, switch to the Network panel, and convert something: you will see the tool code download once, and then nothing else. There is no upload endpoint in the product at all.
