What is a URL Encoder & Decoder?
URL encoding (percent encoding) converts special characters in URLs into a format that can be safely transmitted over the internet. Characters that have special meaning in URLs — like spaces, &, =, ?, #, and non-ASCII characters — must be encoded as percent signs followed by their hexadecimal values. For example, a space becomes %20 and & becomes %26. This ensures the URL is interpreted correctly by servers and browsers regardless of the characters in the original string.
