⚡ Quick Answer

URL encoding converts special characters into a format safe for web URLs. Spaces become %20, & becomes %26, = becomes %3D. Example: 'Hello World!' becomes 'Hello%20World%21'. URL decoding reverses this. Used by web developers, API developers, and anyone working with web links.

🤔 How Does This Work?

URL encoding uses the percent-encoding standard defined in RFC 3986:

Each unsafe character is replaced by a % followed by its two-digit hexadecimal ASCII code
Space (ASCII 32) becomes %20
Ampersand & (ASCII 38) becomes %26
Equals = (ASCII 61) becomes %3D
Letters, digits, and - _ . ~ are left unchanged (URL-safe characters)

Our encoder uses JavaScript's encodeURIComponent() which encodes all special characters. Our decoder uses decodeURIComponent() to reverse the process.

❓ FAQ

What is URL encoding?▼

URL encoding (also called percent encoding) converts characters that are not allowed in URLs into a safe format. Spaces become %20, & becomes %26, special characters like #, ?, = are also encoded. This ensures URLs work correctly in all browsers.

Why do URLs have %20 in them?▼

Spaces are not allowed in URLs. When a URL contains a space, it must be encoded as %20 (the hexadecimal ASCII code for space). Modern browsers often display the space back to you, but the actual URL contains %20.

What is the difference between encodeURI and encodeURIComponent?▼

encodeURI encodes a full URL — it preserves characters like /, ?, &, = that have special meaning in URLs. encodeURIComponent encodes everything including those special characters — used for encoding individual parameters/values within a URL.

When do I need to encode a URL?▼

You need URL encoding when: sending text data in URL query parameters, embedding URLs in HTML, working with APIs, or when your URL contains spaces or special characters like &, =, +, #, or non-ASCII characters.

How do I decode a URL I found online?▼

Paste the URL-encoded text into our decoder and click Decode URL. It will convert %20 back to spaces, %26 back to &, and all other percent-encoded characters back to their original form.
