What is URL Encoder?
URL encoding (percent-encoding) replaces characters that aren't allowed in a URL with a % followed by their hexadecimal code. URLs can only contain a limited set of characters, so spaces, symbols and non-ASCII text must be encoded to travel safely.
There are two common scopes: encoding a whole URL (leaving structural characters like / and ? intact) and encoding a single component such as one query value (escaping everything that isn't safe). Choosing correctly prevents broken links.
About the URL Encoder
The URL Encoder converts text into percent-encoded form so it can be safely placed in a URL or query string. Spaces become %20, ampersands become %26, and other reserved characters are escaped — preventing broken links and malformed requests.
Developers encode URLs constantly: building query parameters, passing values in links, constructing API requests, and handling user input that contains spaces or symbols. This tool offers both component encoding (for individual values) and full-URL encoding, so you pick the right level.
It runs in your browser and is free. Need the reverse? Use our URL Decoder.
