  • Encode full URI

Privacy

Encoding and decoding runs entirely in your browser using native Web APIs. No data leaves your device.

Frequently Asked Questions

URI Component encoding escapes almost every special character, making it ideal for query string values. Full URI encoding leaves characters like : / ? # untouched since they're structurally meaningful in a complete URL.

The tool detects decoding errors and shows a clear message instead of crashing.
