Encode text, URL parameters, or fragments into percent-encoding, or decode encoded strings back to readable text. Supports Chinese, Japanese, Korean, emoji, and common special characters for API debugging, query parameters, and everyday link conversion. Input text and output are processed in the current browser and are not uploaded to LittleOne Tools servers. Decoded results should still be interpreted in the context and security model of the real URL.
