URL Encoder / Decoder
Convert URLs Safely Online
About URL Encoder / Decoder
A URL Encoder/Decoder helps encode or decode URLs to guarantee they are safely transmitted over the Internet. It handles special characters, spaces, and Unicode query structures correctly.
How It Works
The tool provides toggles for full URI encoding (preserving protocol/domain structure) and URI component encoding (escaping query parameters fully). It wraps standard browser encoders with clean Unicode handling.
How to Use URL Encoder / Decoder
- Paste your URL text or query payload into the left input editor panel.
- Choose whether you want to perform Encode or Decode operation.
- Select the encoding type (Encode URI for full URLs, or Encode URI Component for query parameters).
- View the resulting output safely escaped/unescaped in the right pane.
FAQ
Why are there two encoding modes?
`encodeURI` preserves reserved characters like `:` and `/` so a full URL stays valid. `encodeURIComponent` escapes them, which is what you want when embedding a value inside a query parameter.
Under the hood
Wraps the platform's `encodeURI`, `encodeURIComponent`, `decodeURI` and `decodeURIComponent` primitives, with an extra recovery pass that re-decodes mojibake-style double encoding when detected.
