Online URL Encoder & Decoder
Safely encode or decode URLs and query parameters for robust web development.
What is URL Encoding?
**URL Encoding** (also 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 replaced by a `%` followed by their two-digit hexadecimal equivalent.
Why Encode URLs?
URLs can only contain a limited set of characters from the US-ASCII character set. Characters like spaces, brackets, and ampersands have special meanings in a URL structure. To pass these as data within a query parameter, they must be encoded to avoid breaking the link or confusing the web server.
Secure & Private
Our **Online URL Decoder** ensures that your data never leaves your browser. All transformations are performed locally using JavaScript, protecting your sensitive API keys or private URLs from being logged on any server.
