How these tools work

Unlike many online utilities, ToolsOnDuty tools run entirely in your browser using JavaScript. When you paste text, upload a file or enter a value, it is processed on your own device and is never sent to a server. That makes the tools fast, and it keeps sensitive content such as tokens, passwords and private documents completely private.

Because there is no server round-trip, most tools give you a result instantly as you type. They also work on any modern browser and adapt to phones, tablets and desktops, so you can bookmark this page and reach any tool in seconds.
