URL Encoder & Decoder — Encode or Decode URLs Online
Encode any string into a safe URL component, or decode a percent-encoded URL back to readable text — instantly and locally.
What it does
URL Encoder uses the standard encodeURIComponent and decodeURIComponent functions to convert characters like spaces, accents and symbols into their %XX equivalents and back.
When to use it
Use it when building query strings, debugging redirects, decoding tracking links, or sharing URLs with special characters.
Benefits

Example
Encoding hello world&x=1 returns hello%20world%26x%3D1, safe to drop into any query string.
Frequently asked questions
- What's the difference between encodeURI and encodeURIComponent?
- encodeURIComponent escapes more characters (including & = ?), making it the right choice for individual query values.
- Can I decode an entire URL?
- Yes — paste the full URL into the input and click Decode.
- Why does decoding fail?
- The string likely contains invalid percent sequences (e.g. a stray % not followed by two hex digits).
