Encode and Decode URL Text Online
Use this free URL Encoder & Decoder to convert text into percent-encoded form or decode encoded text into a readable format. Enter your text, choose Encode or Decode, and view the result in seconds.
This tool can be useful for web development, working with query parameters, troubleshooting links, and understanding how special characters are represented in URLs.
What Is URL Encoding?
URL encoding, often called percent-encoding, represents certain characters using a percent sign followed by hexadecimal digits. It helps represent characters that have special meaning or cannot be used directly in a particular URL component.
For example, a space in a URI component may be represented as %20. The correct encoding depends on which part of the URL is being handled.
What Is a URL Decoder?
A URL decoder converts percent-encoded text back into its decoded form. This can make encoded values easier to read when inspecting links, query parameters, or text copied from web applications.
Decoding only succeeds when the encoded sequence is valid. Malformed percent sequences may produce an error.
How to Use the URL Encoder & Decoder
- Enter the text or URL component in the input field.
- Click Encode to percent-encode the text.
- Click Decode to convert encoded text back into readable text.
- Review the output.
- Click Copy Result to copy it.
Use the Clear button to remove the input and output before starting another conversion.
URL Encoding Example
| Original text | Encoded component |
|---|---|
hello world | hello%20world |
New York | New%20York |
a&b | a%26b |
These examples illustrate component encoding. Encoding a complete URL as if it were one component can also encode characters that normally separate the URL’s parts.
When Should You Use a URL Encoder?
Query Parameter Values
Encoding can help represent spaces and reserved characters inside a query parameter value. Make sure you encode the value rather than unintentionally changing the URL’s separators.
Web Development
Developers may use URL encoding when preparing data for links, testing applications, or inspecting how text is transmitted in URL components.
Troubleshooting Links
Encoding and decoding can help you examine text in a URL and understand how special characters are represented.
Working with Special Characters
Characters such as spaces, ampersands, and percent signs may need special handling depending on their position and purpose in a URL.
URL Encoding vs. HTML Encoding
URL encoding and HTML encoding are different processes.
URL encoding represents data for use in URL components. HTML encoding represents certain characters in HTML markup so they are not interpreted as markup. Use the encoding method appropriate to the context

Frequently Asked Questions
%20 is the percent-encoded representation of a space character in a URL component.
The tool encodes the input as a URI component. It does not parse a complete URL into its scheme, host, path, query, and fragment. For best results, encode the specific component or value you intend to encode.
Decoding may fail when the input contains malformed percent-encoding, such as a percent sign that is not followed by a valid encoded sequence.
No. URL percent-encoding and Base64 are different encoding methods and serve different purposes.
Yes. It can help with simple encoding and decoding tasks during development and troubleshooting. Always verify the output in the context where it will be used.
