Online URL Decoder
Decode percent-encoded characters, query strings, and URLs
Tip: In URLs, percent codes like %20 decode to spaces, while %26 decodes to &. If decoding double-encoded data, switch on Multi-pass decoding.
What Is URL Decoding?
URL decoding is the process of converting percent-encoded characters in a URL back into their original, readable form.
URLs often contain characters represented using percent-encoding. For example, a space can be represented as %20, while an ampersand can be represented as %26.
A URL decoder reverses this process.
URL decoding is useful when you need to inspect query parameters, understand encoded links, troubleshoot URLs, or recover the readable value contained within an encoded URL component.

How Does URL Decoding Work?
URL encoding uses percent-encoded sequences to represent characters that need to be represented in a URL-safe format. These sequences begin with % followed by two hexadecimal characters.
A URL decoder recognizes these percent-encoded sequences and converts them back into their corresponding characters.
contains %20, which represents a space. After decoding the relevant URL data, the readable value becomes:
URL Decoding Examples
These examples illustrate how percent-encoded characters can be converted back into their original representation.
| Encoded value | Decoded value | Description |
|---|---|---|
| hello%20world | hello world | Percent-encoded space converted to standard space |
| hello%26world | hello&world | Ampersand recovered safely |
| price%3D100 | price=100 | Equals sign restored from parameter value |
| %23section | #section | Hash symbol restored without triggering browser jump |
| search%3Fquery%3Dtest | search?query=test | Question mark and parameter assignments decoded |
| 100%25 | 100% | %25 represents a literal percent character |
| caf%C3%A9 | café | Multi-byte UTF-8 character restored |
| %F0%9F%8C%8D | 🌍 | 4-byte UTF-8 emoji symbol decoded |
What Does a URL Decoder Do?
A URL decoder converts percent-encoded characters into their corresponding readable characters. For example, %26 becomes &, and %3D becomes =.
This is particularly useful when inspecting URL query parameters. Consider this URL:
The value of the q parameter contains encoded characters. After decoding the parameter value, it becomes:
The decoder makes encoded URL data easier to read, inspect, and understand.
When Should You Decode a URL?
There are several situations where an online URL decoder can be useful:
Reading encoded URLs
URLs copied from applications, browsers, logs, or other systems may contain percent-encoded characters that make them difficult to read. Decoding them makes the underlying values readable.
Inspecting query parameters
Query strings frequently contain encoded values like ?q=hello%20world. Decoding reveals original parameters and simplifies troubleshooting.
Debugging web applications
Developers encounter encoded values while debugging redirects, API requests, links, or application-generated URLs, avoiding tedious manual ASCII calculations.
Working with API URLs
API endpoints frequently transmit query parameters with spaces and reserved symbols. Decoding helps developers understand the exact payload being sent.
Analyzing tracking URLs
Marketing and analytics links can contain nested parameters and encoded values. Decoding helps inspect attribution values and UTM tags clearly.
URL Decoder vs URL Encoder
URL encoding and URL decoding are opposite operations.
URL Decoding
Reverses percent-encoding and converts codes back into readable values.
URL Encoding
Converts plain characters into percent-encoded representations.
If you have normal text that needs to be safely represented as part of a URL, use a URL Encoder.
Go to URL EncoderURL Decode vs URL Unencode
You may see the terms URL decode, URL decoding, and URL unencode used when searching for the same type of operation.
In practical terms, they generally refer to converting percent-encoded URL data back into its original character representation. For example, hello%20world can be decoded or “unencoded” to hello world.
The term URL decoding is the standard industry terminology used throughout this page.
What Do Common Percent-Encoded Sequences Mean?
Detailed breakdown of the most frequent characters encountered when decoding URLs:
What Does %20 Mean in a URL?
%20 represents a space character in percent-encoded URL data. For example, 'hello%20world' decodes to 'hello world'. If you encounter %20 in a URL, it usually indicates that a space has been percent-encoded.
What Does %26 Mean in a URL?
%26 is the percent-encoded representation of the ampersand character (&). This distinction matters because & has a special structural role separating query parameters. Encoding it allows an ampersand to be a literal part of a parameter value.
What Does %3F Mean in a URL?
%3F represents the question mark character (?). A question mark has structural meaning in a URL because it normally indicates the beginning of a query string. When part of a value, it appears in encoded form as %3F.
What Does %3D Mean in a URL?
%3D represents the equals sign (=). The equals sign commonly separates a query parameter name from its value. When an equals sign is part of the actual parameter value, encoding it as %3D avoids structural ambiguity.
Can You Decode a Full URL?
Yes, but it is important to understand the difference between a URL's structure and its individual components.
Not every character in a URL should simply be decoded indiscriminately. For example, characters such as ?, &, =, and # have structural meanings within a URL.
For this reason, URL encoding and decoding are often performed on individual URL components or parameter values rather than blindly transforming an entire URL.
When troubleshooting a URL, inspect the encoded component and decode the data that actually needs to be interpreted.
URL Decoding and Query Strings
Query strings are one of the most common places where encoded URL data appears. A URL can contain parameters such as:
Here, q=hello%20world contains the encoded value hello world, while category=shoes contains a value that does not require percent-decoding.
Understanding this distinction is useful when working with web applications, APIs, analytics URLs, and search parameters.
URL Decoding vs Base64 Decoding
URL decoding and Base64 decoding are completely different operations.
URL decoding reverses percent-encoding (hello%20world → hello world).
Base64 decoding converts Base64-encoded strings (often containing padding like ==) back into their original binary or ASCII text data representation.
A Base64 string may look like encoded text, but that does not mean it should be processed with a URL decoder. Use a URL decoder for percent-encoded URL data and a Base64 decoder for Base64-encoded data.
Why Use an Online URL Decoder?
An online URL decoder is useful when you need to inspect encoded data quickly without writing code. Lnkeee's URL Decoder lets you:
It can be useful for developers, SEO professionals, marketers, students, and anyone who works with URLs.
Is URL Decoding Safe?
URL decoding itself is a safe transformation of encoded text into its corresponding character representation. However, decoding a value does not automatically make the resulting content safe to open, execute, or trust.
For example, a decoded URL may point to an external website or contain data that you did not expect. Treat decoded URLs as data and review them carefully before opening unfamiliar links or using decoded values in an application.

About Lnkeee's URL Decoder
Lnkeee provides practical browser-based tools for working with URLs and links. The URL Decoder is designed to make it quick to inspect and convert percent-encoded URL data without requiring additional software.
For accurate results, pay attention to which part of a URL is encoded. URL structure characters such as ?, &, and = can have specific meanings, so decoding an entire URL indiscriminately is not always appropriate.
