The URL Encoder / Decoder is a free online tool that lets you convert special characters to URL-safe format (percent-encoding) and back. Essential for web developers, analysts, and anyone working with URLs containing parameters or special characters.

Simply paste your text or URL, choose the encoding type, and get instant results. Perfect for debugging URLs, preparing query parameters, or decoding received URLs.

How to Use

Enter your text or URL in the input field
Select the encoding type: URL component or full URL
Click "Encode" to convert special characters
Or click "Decode" to get the original text back
Copy the result with one click

What is URL Encoding?

URL encoding (or percent-encoding) is a mechanism that converts non-ASCII characters and reserved characters into a percent sign followed by two hexadecimal digits. For example, a space becomes %20 and the & character becomes %26.

URL Component (encodeURIComponent)

Encodes all special characters. Use it for query parameter values.

Hello & World → Hello%20%26%20World

Full URL (encodeURI)

Preserves URL structure characters (:/?#@). Use it to encode an entire URL.

https://site.com/page?q=test → https://site.com/page?q=test

Use Cases

💻

Web Developers

Prepare query parameters, debug API URLs, or encode data for HTTP transmission.

🔗

Digital Marketing

Create tracking links with UTM parameters containing special characters or spaces.

📊

Data Analysts

Decode URLs from server logs or analytics tools to understand user queries.

🔒

Security

Analyze encoded URLs to detect injection attempts or filter bypass attempts.

Commonly Encoded Characters

Character	Encoded	Description
(space)	%20	Space
&	%26	Ampersand
=	%3D	Equals
?	%3F	Question mark
/	%2F	Forward slash
#	%23	Hash
%	%25	Percent

Best Practices

Query Parameters: Always use encodeURIComponent (URL component) for parameter values.
Full URLs: Use encodeURI (full URL) only when you have a well-formed URL with spaces in the path.
Double Encoding: Avoid encoding a URL twice, which would produce results like %2520 instead of %20.
Unicode Characters: Non-ASCII characters (accents, emojis) are automatically converted to UTF-8 then percent-encoded.
Debugging: When a URL doesn't work, start by decoding it to identify problematic characters.
