Privacy-First Design Philosophy
At UtilBelt, clarity and control are our core principles. We understand that data privacy is critical, especially when dealing with personal files or credentials.
Uniquely, many of our tools—such as the Password Generator, PDF Compressor, and File Diff tool—function entirely client-side.
This means that the data you process often never leaves your device. The calculations and operations are performed directly by your web browser, ensuring that your files remain private and are not stored on our servers.
