Make text URL-safe
Percent-encode text so it’s safe inside a URL or query string, or decode %xx sequences back to readable characters. Essential when building links with user input or special characters.
When you need it
Spaces become %20, and reserved symbols like &, ?, = and / must be encoded inside a value so the server doesn’t misread where the URL ends and the data begins.
Runs entirely in your browser — paste anything, nothing is uploaded.
