URL Encoder / Decoder

Encode and decode URL components. All processing happens in your browser.

encodeURIComponent encodes all special characters including : / ? # & = — best for encoding individual query parameter values.

What is URL Encoder/Decoder?

URL Encoder/Decoder encodes and decodes URL components using standard JavaScript functions (encodeURIComponent and encodeURI), correctly handling special characters in query strings and path segments. It supports both component-level encoding for individual parameters and full URL encoding for complete addresses.

How to Use

  1. Choose between component mode (for query parameters) or full URL mode (for complete URLs)
  2. Paste your URL or text containing special characters into the input field
  3. Click Encode to percent-encode the text, or Decode to convert it back to readable form

Use Cases

  • Encoding query parameters that contain spaces, ampersands, or other reserved characters
  • Fixing broken URLs that contain unescaped special characters or Unicode
  • Decoding percent-encoded strings from server logs or API responses
  • Building dynamic URLs with user-supplied values in web applications

Privacy & Security

All processing happens entirely in your browser. Your data is never sent to any server. You can verify this by checking the network tab in your browser's developer tools — you'll see zero outbound requests.
