URL Encoding Without A Round Trip To A Server

URLs often carry tokens, ids and search terms. This encodes and decodes locally, so the string you paste is never transmitted.

Nothing Leaves The PageYour text is transformed in the browser. No request is made and nothing is stored.

Component Or Whole URLencodeURIComponent for query values, encodeURI when the string is already a URL.

Unicode SafeNon-ASCII characters are percent-encoded correctly as UTF-8.

Round Trips CleanlyDecode what you encoded and get exactly what you started with.

InstantRuns as you type — no button to press and no waiting on a server.

Works OfflinePure JavaScript with no dependencies, so it keeps working with no connection.
