Decode URL-encoded text instantly, accurately, and privately. Convert confusing percent-encoded strings back into readable characters right in your browser.
Why Use Our URL Decoder?
A professional-grade utility designed for speed, accuracy, and privacy.
Browser-Based Privacy
Decoding happens locally in your browser using JavaScript. We never send your sensitive URLs or API tokens to a server.
Query String Support
Includes an explicit option to treat the plus sign (+) as a space, perfectly handling application/x-www-form-urlencoded data.
UTF-8 Unicode Ready
Safely decodes complex international characters, emojis, and special symbols encoded in standard UTF-8 format.
What Is URL Decoding?
URL decoding is the process of translating percent-encoded characters back into their original, readable form. Because the internet relies on strict protocols (like RFC 3986), URLs can only be transmitted using a limited set of ASCII characters.
When a URL contains a space, a special symbol, or a non-English character, the browser "encodes" it by replacing the unsafe character with a percent sign (%) followed by two hexadecimal digits (e.g., a space becomes %20).
Our tool instantly reverses this process, allowing you to read the original text.
URL Encoding vs URL Decoding
| Process | Description | Example |
|---|---|---|
| Encoding | Converts unsafe characters into URL-safe hexadecimal sequences. | Hello World → Hello%20World |
| Decoding | Converts safe hexadecimal sequences back into readable text. | Hello%20World → Hello World |
Who Uses This Tool?
- Web Developers: Debugging API requests, testing GET parameters, and inspecting server logs.
- SEO Professionals: Analyzing complex, encoded URLs to understand tracking parameters and UTM tags.
- QA Testers: Inspecting form submissions and ensuring data is transmitted correctly.
- General Users: Cleaning up messy, unreadable links before sharing them with others.
Understanding Query Strings and the Plus Sign (+)
One of the most confusing aspects of URL decoding is how spaces are handled. In the path of a URL, a space is encoded as %20. However, in a query string (the part of a URL after the ?), HTML forms submitted via the GET method use a standard called application/x-www-form-urlencoded. Under this standard, spaces are replaced with a plus sign (+).
This is why our URL Decoder provides an explicit option: Treat + as space. Use this option when decoding data from form submissions or query parameters.
