About URL Encoder

The URL Encoder applies percent-encoding to your text so characters like spaces, ampersands, and slashes can be placed safely inside a URL, query string, or form value. It prevents the broken links and mangled parameters that unencoded special characters cause. Encoding runs locally in your browser with nothing uploaded. To reverse it, use the URL Decoder, and to assemble parameters use the URL Query Builder.

How to Use

  1. 1Open URL Encoder and paste or type your data into the input area.
  2. 2Adjust any available options to match the result you want.
  3. 3Your output is generated instantly — no button-clicking required for most tools.
  4. 4Use the Copy or Download button to save your result.

Common Use Cases

  • Encoding data for URLs, APIs, and data URIs
  • Debugging tokens, headers, and encoded payloads
  • Converting between text, hex, binary, and Base64
  • Safely embedding special characters in code and markup

Frequently Asked Questions

What is percent-encoding?

Percent-encoding replaces unsafe characters with a % followed by their hex code — a space becomes %20, for example — so the value can travel inside a URL without breaking it.

Should I encode the whole URL or just parts?

Usually you encode individual components like query parameter values, not the entire URL, so that structural characters such as / and ? keep their meaning. This tool lets you encode exactly the text you paste.

Is URL Encoder free to use?

Yes. URL Encoder is completely free with no sign-up, no subscription, and no usage limits. Every tool on CodeUtilityKit is free forever.

Is my data safe when I use URL Encoder?

Absolutely. URL Encoder runs entirely in your browser. Your input is processed locally with JavaScript and is never sent to, stored on, or logged by any server — so it is safe even for private or sensitive data.
