Encode and Decode URL Components
Encode text for use as a URL component or decode a percent-encoded value. The tool handles malformed input clearly and keeps all processing local.
URL components are encoded and decoded locally.
Uses component encoding, so reserved URL characters are escaped as part of the value.
What you can do with this tool
- Encode and decode individual URL components with browser-native functions.
- Handle malformed percent-encoding with a useful validation message.
- Copy or download results without sending input to a server.
How to use URL Encoder and Decoder
- Choose Encode or Decode.
- Enter the source text or percent-encoded component.
- Run the operation, then copy or download the result.
When this tool is useful
- Encode a search value or other text before placing it in a URL query component.
- Decode percent-encoded text when inspecting a URL or request.
Limits and privacy
This tool operates on one URL component, not an entire URL. Encoding a full address can escape separators that must remain structural. Encoding and decoding use browser-native functions locally.
Frequently asked questions
Does this encode a complete URL?
The tool encodes or decodes a URL component. Reserved characters are escaped, so use it for a value or component rather than a complete URL.
What if the encoded text is malformed?
The tool reports malformed percent-encoding and leaves the output empty.
Is my text sent anywhere?
No. URL encoding and decoding use browser-native functions locally.
