About this tool
Encode and decode URLs and query parameters for safe transmission. URL encoding (percent-encoding) replaces unsafe characters with a % followed by two hexadecimal digits — for example, spaces become %20, ampersands become %26, and non-ASCII characters are encoded as UTF-8 byte sequences. Our tool encodes text for use in URL query strings, path segments, and form data, and decodes percent-encoded strings back to readable text. Essential for building API requests, constructing query strings, debugging encoded URLs, and working with any system that transmits data via URLs. Uses the standard encodeURIComponent/decodeURIComponent functions for full Unicode support.
