URL Encoder & Decoder – Encode and Decode URLs Online

The URL Encoder & Decoder is a powerful online tool that allows users to quickly convert text or URLs into a percent-encoded format and decode encoded URLs back into readable text. URL encoding is an essential process in web development, data transmission, and API communication because certain characters cannot be safely transmitted within a URL without encoding.

Our free online URL Encoder & Decoder helps developers, web administrators, and digital professionals encode special characters into a format that web browsers and servers can correctly interpret. Whether you are working with query parameters, web forms, APIs, or data processing, this tool provides an efficient way to handle URL encoding and decoding tasks.

The tool is designed to be fast, accurate, and easy to use, making it suitable for beginners as well as experienced developers.

What is URL Encoding?

URL Encoding, also known as percent encoding, is a mechanism used to convert characters into a format that can be safely transmitted in a Uniform Resource Locator (URL). Some characters, such as spaces, punctuation marks, and special symbols, are not allowed in URLs because they may interfere with how browsers interpret the address.

To avoid errors, these characters are replaced with a percent sign (%) followed by a two-digit hexadecimal value representing the ASCII code of the character.

For example:

Example conversion:

Original text:

Encoded URL:

This process ensures that URLs remain valid and can be transmitted correctly across the internet.

To understand the technical details of percent encoding, you can read the documentation provided by Mozilla Developers, which explains how encoding works in web applications.

What is URL Decoding?

URL Decoding is the reverse process of URL encoding. It converts percent-encoded characters back into their original readable form.

For example:

Encoded string:

Decoded result:

Decoding is useful when working with encoded query strings, API responses, or encoded URLs received from external sources. Our URL Decoder instantly converts encoded values back into their original text format.
