Quick guide
- Choose Complete URL for a whole address or Component for one query value, then paste the input.
- Choose Encode for a readable URL or Decode for an existing percent-encoded value.
- Complete URL preserves structural separators. Component escapes characters such as &, =, and / so the output can be inserted as one query value.
Check
Validate the result
Encode https://example.com?q=서울 역 and then decode the result. A correct round trip returns the original text while representing the space and Korean text with percent sequences.
Limits
Know the limits
Complete URL pairs encodeURI with decodeURI; Component pairs encodeURIComponent with decodeURIComponent. Complete URL decoding preserves escaped reserved separators such as %2F. Re-encoding an encoded input causes double encoding.

FAQ
Frequently asked
Are %20 and a plus sign always the same kind of space?
%20 is a percent-encoded space. A plus sign may represent a space in form-encoded query data, but a general URL decoder can preserve it as a literal plus sign.
