URL Encoder/Decoder

What is URL Encoding/Decoding Tool?

The URL Encoding/Decoding Tool is an online utility that converts special characters in a URL into a format that can be transmitted safely over the internet. It replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits.

Decoding reverses this process, restoring the original characters for readability and usability. This ensures that URLs function correctly in browsers, APIs, and web applications.

This tool encodes and decodes using standard percent-encoding. It supports automatic conversion while typing and includes an option to escape every character, useful for strict contexts or security reviews. Decoding restores the original readable text.

Key Features

• Converts unsafe characters like spaces, commas, and symbols into valid URL entities
• Decodes already encoded URLs to restore their human-readable form
• Works instantly with real-time encoding and decoding
• Handles long URLs, form data, and query strings efficiently
• Prevents broken links and parameter errors during transmission

What does an URL encoder do?

A URL encoder converts special characters into their percent-encoded equivalents to ensure proper transmission through web servers and browsers.
For example:

• Space ( ) becomes %20
• Question mark (?) becomes %3F
• Ampersand (&) becomes %26

Use Cases:

• Encoding query parameters for GET and POST requests
• Ensuring compatibility between systems that use different character sets
• Safeguarding URLs in HTML forms, APIs, and JavaScript code
• Avoiding data corruption caused by unescaped characters
