TOOLS / NO LOGIN

Local utilities, clear outputs.

Choose an operation. Inputs stay in the browser, and the result is derived directly from what you enter.

Parse and format JSON. Invalid data is reported, never silently rewritten.

Encode query values or decode percent-encoded input with UTF-8 validation.

DATA / PRIVACY

Designed for ordinary use.

Neither utility sends your text to an API. All processing uses built-in browser methods and DOM updates that display text without executing it.

For sensitive content, consider local policies around browser history, screenshots and extensions even when a site performs no network request.
