URL Encoder & Decoder
Encode a URL component with percent escapes or decode a percent-encoded string without changing unrelated text.
About this tool
How it works
- Copy the encoded component into a query parameter, or verify the decoded string before reuse.
- The operation applies to one URL component, not an entire address; malformed percent escapes cause a decoding error.
Type the value of a URL query parameter, such as café & tea, then select Encode or Decode.
Example: hello world & café
