Understanding the URL Encode / Decode

URL encoding (also called percent-encoding) replaces characters that are unsafe or reserved in a web address with a % followed by their hexadecimal byte value — a space becomes %20, an ampersand becomes %26. It keeps query strings, form data and links valid when they contain spaces, symbols, or non-English characters.

Anyone building links, REST APIs, UTM tracking URLs or web forms needs it constantly. This tool encodes text for safe use inside a URL and decodes percent-encoded URLs back to readable text — instantly and privately in your browser, with nothing uploaded.
