Questions before you begin?

Which Design tools run locally?
Every card carries an execution label. Local tools keep active input in the browser; cloud and hybrid tools explain external processing before it begins.
Will a Design transformation change my source?
Toolars works on a separate browser copy. Your original file or text stays unchanged unless you intentionally download and replace it.
Can I save a tool?
Yes. Guest favorites stay in this browser. An account can sync favorites after authentication is configured.
How do I report an incorrect result?
Each tool page includes a report surface. Submitted feedback contains only the message and page context you choose to send.
