URL Encoder & Decoder
Encodes and decodes URLs using encodeURIComponent and encodeURI.

What URL Encoder & Decoder does
URL Encoder & Decoder is a web utility that converts strings containing special characters into percent-encoded format and reverses the process, ensuring URLs are properly formatted for web applications. Users input a URL or string on one side of the interface and receive both the encoded and decoded versions simultaneously, which helps maintain accurate representation across digital platforms. The tool applies standard web encoding protocols, such as encodeURIComponent for individual parameters or encodeURI for entire Uniform Resource Locators, making it suitable for developers and web engineers who need to handle query parameters and other URL components reliably.
How to use the DevBolt URL Encoder & Decoder

Best for
Developers and web engineers who need to quickly encode or decode URL components and query parameters while working on web applications.

URL Encoder & Decoder FAQ
- What is the difference between encodeURI and encodeURIComponent?
- encodeURI encodes a complete Uniform Resource Locator, leaving certain characters like letters, digits, and : / ? @ & = + $ - _ . ! ~ * ' ( ) reserved, while encodeURIComponent encodes a URI component such as a query parameter, converting all characters except letters, digits, and . _ - ~ to their percent-encoded form.
- Can this tool handle non-ASCII characters like emoji or accented letters?
- Yes, the encoder converts non-ASCII characters including emoji and accented letters into their percent-encoded UTF-8 representation, making them safe for inclusion in URLs and query strings.
- Is the encoded output compatible with all web servers and browsers?
- The percent-encoded format follows standard web protocols and is widely compatible with web servers and browsers, ensuring that special characters are transmitted correctly in URLs and query parameters.
- Do I need to manually choose between encoding the whole URL or just parts of it?
- The tool provides both encodeURI and encodeURIComponent functionality, so you can select the appropriate method based on whether you are encoding an entire URL or just individual components like query parameters.
