URL Encoder/Decoder
Privacy First: Your files are processed securely. Whenever possible, processing happens in your browser and files are never stored on our servers.
Convert URLs and query string parameters to and from percent-encoded format. Special characters - spaces, non-ASCII letters, ampersands, equals signs, and punctuation - must be encoded as percent sequences before being included in a URL (space becomes %20, @ becomes %40). In encoding mode, paste any raw text including non-ASCII characters and symbols to get the correctly percent-encoded string. In decoding mode, paste any percent-encoded URL to get the human-readable original text. Supports full URL encoding and component encoding (encoding only URL delimiter characters within a specific component). All processing runs in your browser. No account required.
