URL Encoder & Decoder

Instantly convert special characters into safe web links, or decode them back to readable text.

How to Encode and Decode URLs?

Web addresses (URLs) can only be sent over the internet using the ASCII character set. If your URL contains spaces or special characters (like `?`, `=`, or `&`), they must be converted into a valid format. Our free URL Encoder & Decoder tool handles this instantly:

  1. Paste Your Data: Drop your raw text, query string, or messy URL into the top input box.
  2. Encode: Click "Encode URL" to replace unsafe characters with a `%` followed by two hexadecimal digits (e.g., a space becomes `%20`). This is known as Percent-Encoding.
  3. Decode: If you have a messy URL full of `%20` or `%3F`, click "Decode URL" to translate it back into human-readable text.

Frequently Asked Questions (FAQ)

What is Percent-Encoding?

Percent-encoding is a mechanism for encoding information in a Uniform Resource Identifier (URI). Because URLs cannot contain spaces or certain symbols, those characters are translated into a percent sign (`%`) followed by their hexadecimal equivalent. For instance, a space character translates to `%20`.

Is it safe to decode private API keys or tokens here?

Absolutely. This tool is built entirely on client-side JavaScript. This means your URLs and query parameters are processed locally by your own browser. None of your data is ever transmitted, logged, or saved to our servers.
