Professional URL Encoder & Decoder

Convert special characters into a format safe for transmission over the internet. A vital utility for developers working with APIs, query strings, and deep linking.

What is URL Encoding (Percent-Encoding)?

URL Encoding, also known as Percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). Although it is known as URL encoding, it is, in fact, used more generally within the main URI set, which includes both URL and URN.

Characters allowed in a URL are either reserved or unreserved. Reserved characters (like ?, &, =) have special meanings. If you need to include these characters as part of the data in a query string, they must be encoded to prevent the browser from misinterpreting them.

How to Use This Tool

  1. Input: Paste the link or text you want to transform into the editor above.
  2. Action: Click **"Encode"** if you are preparing a string for a URL parameter, or **"Decode"** if you have a link with %20 or %3F symbols that you want to read in plain text.
  3. Verification: Our tool uses standard UTF-8 encoding to ensure compatibility across all modern browsers and servers.
  4. Implementation: Copy the result and use it in your code, API requests, or browser address bar.

Why is URL Encoding Important?

API Development

When sending data to a REST API via GET requests, special characters in names or titles can break the query. Encoding ensures the data reaches the server intact.

Social Sharing

URLs shared on platforms like WhatsApp or Facebook often contain titles with spaces. Encoding these prevents broken links when users click them.

Security & XSS

Encoding input data is a fundamental layer of security to prevent Cross-Site Scripting (XSS) attacks by neutralizing harmful scripts in the URL.

Non-ASCII Support

Standard URLs only support a limited set of ASCII characters. Encoding allows for non-English characters (like Arabic or Emojis) to be transmitted safely.

Common Encoded Characters

Character Meaning Encoded Value
Space Separator %20 or +
? Start of query string %3F
& Parameter separator %26
= Key/Value separator %3D
