How to use
- Open the tool — Open this LocalKit page and wait for the interactive controls to load.
- Provide input — Paste or type your content (or set options). Data stays in the browser.
- Run the action — Use the primary button or live controls to generate the result.
- Copy the result — Copy the output into your editor, terminal, or documents.
Limits
Requires JavaScript. Extremely large inputs may slow the browser tab. Results depend on your browser APIs; there is no server-side processing quota because nothing is uploaded.
When to use
When you want a quick, free utility without creating an account or sending content to an online converter.
When not to use
When you need server-side integration, batch automation at scale, or certified compliance tooling.
Privacy note
Tool inputs are processed in your browser only. Theme, language and favorites may use localStorage; hosting may keep standard access logs (IP, UA, URL) without tool payloads.
