How privacy works
The work happens here, not on our servers.
ConvertRS uses browser APIs and WebAssembly to read and process supported files inside this tab. There is no file-transfer step hidden behind the interface.
- 01 Your browser opens the file
The file is read from the device you are using.
- 02 Local engines do the work
Browser code and WebAssembly create the result in this tab.
- 03 You download the result
The finished file is saved without a server upload or account.
