Free URL Encode and Decode Tool

What is URL encoding?

URL encoding, also called percent-encoding, replaces characters that are unsafe or reserved in a URL with a percent sign followed by their hexadecimal byte value. For example a space becomes %20 and an ampersand becomes %26. It keeps query strings, path segments, and form values from breaking a URL, and it lets you carry spaces, accents, and symbols safely in a link or an API request.

How to use this URL tool

Paste your text in the Input box, then click Encode to percent-encode it, or Decode to turn an encoded string back into readable text. The result appears in the Output box, ready to copy. The tool is UTF-8 safe, so multibyte characters are encoded and decoded correctly. Everything runs in your browser, so nothing you paste is uploaded.

URL encoding FAQ

When do I need to URL-encode? Whenever a value goes into a query parameter, a path segment, or a form body and could contain spaces, ampersands, equals signs, or non-ASCII characters.

What is the difference from Base64? URL encoding only escapes unsafe characters and keeps the rest readable. Base64 rewrites the whole value into a different alphabet.

Is my data safe? Yes. This tool runs entirely in your browser and never sends your input anywhere.
