Why use browser-based developer utilities?

Small formatting, encoding, validation, and conversion tasks should be easy to complete. These online developer tools keep the workflow short, explain the expected input, and make the result easy to copy or download.

For tools that support local processing, your input stays in the current browser session. Always read the notice shown on the individual tool page before using sensitive or production data.
