01How to use the URL Encoder/Decoder

  1. 01Choose Encode component for a single query value, Encode full URL for a whole address, or Decode.
  2. 02Paste your text.
  3. 03Copy the result.

02Encoding rules

Unsafe characters become % followed by their UTF-8 bytes in hex.
  space → %20      é → %C3%A9      & → %26

Encode component   also encodes : / ? # & = +
                   (use for a single parameter value)
Encode full URL    keeps : / ? # & = so the URL still works
Decode             also treats + as a space

03Examples

“café & crème” as a component: caf%C3%A9%20%26%20cr%C3%A8me.

https://example.com/a b encodes to https://example.com/a%20b as a full URL.

%E2%9C%93 decodes to ✓.

04Frequently asked questions

Which mode should I use?

Use Encode component for values you insert into a URL, such as a search term. Use Encode full URL only when you have a complete address with spaces or non-ASCII characters.

Why is + decoded as a space?

HTML forms encode spaces as + in query strings. If your data has a literal plus sign, it should be encoded as %2B.

What does “invalid percent-encoding” mean?

A % must be followed by two hexadecimal digits that form valid UTF-8. A lone % or %ZZ can’t be decoded.
