Developer Tools FAQ
Are my files secure when processing online?
Yes, your files are completely secure when processing online with ToolSphere because tasks execute client-side inside your local browser using WebAssembly and HTML5 APIs. Files are never stored permanently, and any temporary conversion buffers are purged automatically within 1 hour.
Do I need to install any apps or browser extensions?
No installation is required to use ToolSphere. The entire utility platform operates natively in standard web browsers across Mac, Windows, Linux, iOS Safari, and Android Chrome with zero plugins or downloads.
