%22 is the URL-encoded double quote (").
In a URL, %22 stands for the double quote ("). Here is when to encode it, what it does in each part of a URL, and what every major language outputs.
Quick facts
| Character | " |
|---|---|
| Name | Double quote |
| Unicode | U+0022 |
| UTF-8 bytes | 22 (1 byte) |
| Percent-encoded | %22 |
| Lowercase form | %22 — identical meaning |
| Double-encoded | %2522 |
| HTML form encoding | %22 |
| RFC 3986 class | Not allowed in URLs |
| HTML entity | " |
What it means in a URL
A double quote is not allowed raw in a URL and must always be encoded as %22. Browsers encode it automatically in paths and queries because a raw quote would end an HTML attribute such as href="…".
RFC 3986 class: Not allowed in URLs. It is outside the characters RFC 3986 permits, so it must always be percent-encoded.
When to encode it
| Where it appears | What to do |
|---|---|
| Path segment | Encode |
| Query value | Encode |
| Fragment | Encode |
| Form body | Encode |
The mistake to watch for
Building a link inside HTML without encoding the quote, which closes the href attribute early and breaks the page — or opens it to injection.
What each language produces
Every function in this table encodes it. Output for the single character, UTF-8 input, tested against the real runtimes (see the encoding comparator for your own strings).
| Function | Output | |
|---|---|---|
| JavaScript encodeURIComponent(s) | %22 | encoded |
| JavaScript encodeURI(s) | %22 | encoded |
| JavaScript URLSearchParams | %22 | encoded |
| Python urllib.parse.quote(s) | %22 | encoded |
| Python quote(s, safe="") | %22 | encoded |
| Python urllib.parse.quote_plus(s) | %22 | encoded |
| PHP rawurlencode($s) | %22 | encoded |
| PHP urlencode($s) | %22 | encoded |
| Java URLEncoder.encode(s, UTF_8) | %22 | encoded |
| Go url.QueryEscape(s) | %22 | encoded |
| Go url.PathEscape(s) | %22 | encoded |
| Ruby URI.encode_www_form_component(s) | %22 | encoded |
| Ruby ERB::Util.url_encode(s) | %22 | encoded |
| C# / .NET Uri.EscapeDataString(s) | %22 | encoded |
Decoding it
decodeURIComponent('%22') returns the double quote ("). Python: urllib.parse.unquote('%22'); PHP: rawurldecode('%22'). Paste any string into the URL decoder to decode it in your browser.

Common questions.
%22 is the percent-encoded form of the double quote ("), whose byte value is 0x22. Decoding the URL turns it back into the character.
Yes. Hex digits in percent-encoding are case-insensitive, so %22 and %22 mean the same thing. RFC 3986 recommends uppercase, and mixing cases can make caches and analytics count one URL as two.
Use your language’s encoder on the value: encodeURIComponent in JavaScript gives %22, Python’s quote(s, safe="") gives %22, PHP’s rawurlencode gives %22.
