🔗 URL Encoder
URL-encode or decode text for safe use in query strings.
Percent-encode a URL or a query string so it survives being passed as a parameter, or decode an escaped URL back into readable text.
How to use the URL Encoder
- Paste the URL or the text you want to encode.
- Choose Encode or Decode, and switch between component and full-URI mode.
- Copy the escaped result.
Why people use it
- Fixes the classic bug where an ampersand inside a query value silently truncates the parameter.
- Component mode escapes :, / and ? so a nested URL can be passed as a single value.
- Decoding turns a wall of percent signs back into something readable.
Frequently asked questions
What is the difference between encodeURI and encodeURIComponent?
encodeURI leaves the structural characters :, /, ?, &, = and # intact so a whole URL stays a valid URL. encodeURIComponent escapes those too, which is what you want when a URL is being passed as a value inside another URL.
Why do spaces appear as %20 or as +?
%20 is percent-encoding, used anywhere in a URL. The + sign is a separate convention from HTML form encoding in query strings. Both decode to a space, but they are not interchangeable in every context.
Do I need to encode an entire URL?
Usually not. Encode only the parts that carry data, such as a search term or a redirect target, and leave the scheme, host and path separators alone.
