URL Decoder
Decode a percent-encoded URL component with JavaScript decodeURIComponent.
How to use
- Enter the encoded component and run decoding.
Capabilities and scope
Malformed percent escapes cause URIError rather than a partial result.
How it works
The tool calls decodeURIComponent(input).
Example
hello%20world becomes hello world.
Useful for
- Read encoded query values or path fragments
Before you use it
- The application/x-www-form-urlencoded convention that treats + as a space is not applied automatically.
Frequently asked questions
Does + become a space?
No. decodeURIComponent leaves plus signs unchanged.
