URL Encoder/Decoder
Encode and decode URLs, URL components, and parse query strings. All processing happens locally in your browser.
Component encoding (encodeURIComponent) - Best for query parameters and path segments

What is URL Encoding (Percent-Encoding)?
URL encoding, officially known as Percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). Characters that are not allowed in a URL must be encoded so they can be transmitted safely over the internet.
The encoding consists of a percent sign followed by the two-hexadecimal-digit representation of the character's ASCII value. For example, a space becomes %20, and a pound sign (#) becomes %23.
encodeURI vs. encodeURIComponent: When to Use Which?
Our tool supports both common methods of encoding in JavaScript:
- encodeURIComponent (Component): Encodes almost all special characters, including
/ , ? : @ & = + $ #. This is the best choice for encoding individual query parameter values. - encodeURI (Full URL): Preserves characters that have special meaning in a URL (like
http://). Use this when you want to encode a complete URL but keep the protocol and domain structure intact.
Why Use Our URL Parser?
Beyond simple encoding, our Query String Parser breaks down complex URLs into a readable table of key-value pairs. This is invaluable for debugging tracking pixels, UTM parameters, or complex OAuth redirect URIs. Like all our tools, this parsing happens entirely within your browser for maximum privacy.
🔒 Privacy Commitment
Like all tools in the Dev Tool Kit, this URL Encoder/Decoder operates 100% client-side. Your data is processed locally in your browser and is never sent to our servers. Privacy is not just a feature; it's our core architecture.
