URL Encoder/Decoder

Instantly format URLs for the web or decode complex query strings with our free online tool. Whether you are a developer fixing broken links, a marketer tracking UTM parameters, or an SEO specialist auditing site structure, this tool ensures your URLs are safe and readable.

Why do I need to Encode URLs?

URLs can only contain a limited set of characters (ASCII). If your URL contains spaces, special symbols (like &, %, $), or non-English characters, they must be converted into a valid format known as Percent-Encoding.

• Encoding: Converts special characters into safe code (e.g., a space becomes %20).

• Decoding: Converts strings like %20 or %40 back into readable text.

Features

• Safe Query Parameters: Ensures your UTM tags and API keys are transmitted correctly without breaking the URL structure.

• Client-Side Security: Your URLs and data are processed instantly in your browser. Nothing is uploaded to a server.

• Error Detection: Automatically alerts you if a URL string is malformed and cannot be decoded.

How to Use

1. Paste your URL or text into the “Input” box.

2. Click “Encode” to convert special characters to their percent-encoded format.

3. Click “Decode” to revert an encoded URL back to plain text.

4. Hit “Copy Result” to use it immediately.
