What Is a URL Encoder and Decoder?

A URL encoder converts text and special characters into a format that can be safely represented in URL data. This is useful because some characters have reserved meanings in web addresses and query parameters.

A URL decoder performs the reverse operation, converting percent-encoded values back into readable text so encoded URLs and parameters are easier to inspect and troubleshoot.

How to Use the URL Encoder & Decoder

Enter or paste a URL, query parameter or text.
Click Encode URL to percent-encode the value.
Click Decode URL to restore encoded text.
Review the converted value in the same text area.
Click Copy Result to copy the result.

What Is Percent-Encoding?

Percent-encoding represents certain characters with a percent sign followed by hexadecimal values. It is commonly encountered in query strings and other URL components when a character needs a safe encoded representation.

Example: a space in the text Hello World is represented by %20 when encoded with encodeURIComponent().

When Is URL Encoding Useful?

Preparing query parameter values for web applications.
Working with API requests and responses.
Sharing URLs that contain special characters.
Inspecting encoded parameters while debugging.
Testing URL values during web development.
Converting encoded text back into a readable form.
