Free Online URL Encoder / Decoder Tool

Our free online URL Encoder / Decoder allows you to convert special characters into safe URL percent-encoded format or decode encoded strings back into plain, readable text instantly.

What is URL Encoding?

URL encoding (also known as percent-encoding) is a mechanism used to encode information in a Uniform Resource Identifier (URI). URLs can only contain a limited set of ASCII characters (alphanumeric characters and a few unreserved symbols). Any reserved or special character—such as spaces, ampersands (&), question marks (?), or slash symbols (/)—must be encoded into a percent sign followed by hexadecimal values.

Why is URL Encoding Necessary?

• Prevents Syntax Errors: Ensures that web servers interpret query string parameters correctly without breaking link structures.
• Handles Special Characters: Safely transmits characters outside the standard ASCII set (including foreign characters and emojis).
• Security & Data Integrity: Protects data passed via GET parameters in HTTP requests.

How to Use This Tool?

• To Encode: Paste your plain text or raw URL into the input field and click Encode URL.
• To Decode: Paste an encoded URL (e.g., text containing %20 or %26) and click Decode URL.
• Copy: Click the Copy Result button to copy the output directly to your clipboard.
