Twitter Emoji (Twemoji) Build Status

A simple library that provides standard Unicode emoji support across all platforms.

Twemoji v14.0 adheres to the Unicode 14.0 spec and supports the Emoji 14.0 spec. We do not support custom emoji.

The Twemoji library offers support for all Unicode-defined emoji which are recommended for general interchange (RGI).


CDN Support

The folks over at MaxCDN have graciously provided CDN support.

MaxCDN is shut down right now, so in the meanwhile use a different CDN or download the assets. (See Maxcdn has shut down, cdn not working anymore. · Issue #580 · twitter/twemoji).

Use the following in the <head> tag of your HTML document(s):

<script src="" crossorigin="anonymous"></script>

This guarantees that you will always use the latest version of the library.

If, instead, you'd like to include the latest version explicitly, you can add the following tag:

<script src="" integrity="sha384-ICOlZarapRIX6UjKPcWKEpubjg7lGADN7Y9fYP4DU9zm0aPFhgnP5ef+XFaPyKv+" crossorigin="anonymous"></script>


If instead you want to download a specific version, please look at the gh-pages branch, where you will find the built assets for both our latest and older versions.


Following are all the methods exposed in the twemoji namespace.

twemoji.parse( ... ) V1

This is the main parsing utility and has 3 overloads per parsing type.

Although there are two kinds of parsing supported by this utility, we recommend you use DOM parsing, explained below. Each type of parsing accepts a callback to generate an image source or an options object with parsing info.

The second kind of parsing is string parsing, explained in the legacy documentation here. This is unrecommended because this method does not sanitize the string or otherwise prevent malicious code from being executed; such sanitization is out of scope.

DOM parsing

If the first argument to twemoji.parse is an HTMLElement, generated image tags will replace emoji that are inside #text nodes only without compromising surrounding nodes or listeners, and completely avoiding the usage of innerHTML.

If security is a major concern, this parsing can be considered the safest option but with a slight performance penalty due to DOM operations that are inevitably costly.

var div = document.createElement('div');
div.textContent = 'I \u2764\uFE0F emoji!';


var img = div.querySelector('img');

// note the div is preserved
img.parentNode === div; // true

img.src;        //
img.alt;        // \u2764\uFE0F
img.className;  // emoji
img.draggable;  // false

All other overloads described for string are available in exactly the same way for DOM parsing.

Object as parameter

Here's the list of properties accepted by the optional object that can be passed to the parse function.

    callback: Function,   // default the common replacer
    attributes: Function, // default returns {}
    base: string,         // default MaxCDN
    ext: string,          // default ".png"
    className: string,    // default "emoji"
    size: string|number,  // default "72x72"
    folder: string        // in case it's specified
                          // it replaces .size info, if any


The function to invoke in order to generate image src(s).

By default it is a function like the following one:

function imageSourceGenerator(icon, options) {
  return ''.concat(
    options.base, // by default Twitter Inc. CDN
    options.size, // by default "72x72" string
    icon,         // the found emoji as code point
    options.ext   // by default ".png"


The default url is the same as twemoji.base, so if you modify the former, it will reflect as default for all parsed strings or nodes.


The default image extension is the same as twemoji.ext which is ".png".

If you modify the former, it will reflect as default for all parsed strings or nodes.


The default class for each generated image is emoji. It is possible to specify a different one through this property.


The default asset size is the same as twemoji.size which is "72x72".

If you modify the former, it will reflect as default for all parsed strings or nodes.


In case you don't want to specify a size for the image. It is possible to choose a folder, as in the case of SVG emoji.

twemoji.parse(genericNode, {
  folder: 'svg',
  ext: '.svg'

This will generate urls such instead of using a specific size based image.


Basic utilities / helpers to convert code points to JavaScript surrogates and vice versa.


For a given HEX codepoint, returns UTF-16 surrogate pairs.

 // "\ud83c\udde8"


For given UTF-16 surrogate pairs, returns the equivalent HEX codepoint.

 // "1f1e8-1f1f3"

 twemoji.convert.toCodePoint('\ud83c\udde8\ud83c\uddf3', '~');
 // "1f1e8~1f1f3"


Inline Styles

If you'd like to size the emoji according to the surrounding text, you can add the following CSS to your stylesheet:

img.emoji {
   height: 1em;
   width: 1em;
   margin: 0 .05em 0 .1em;
   vertical-align: -0.1em;

This will make sure emoji derive their width and height from the font-size of the text they're shown with. It also adds just a little bit of space before and after each emoji, and pulls them upwards a little bit for better optical alignment.

UTF-8 Character Set

To properly support emoji, the document character set must be set to UTF-8. This can be done by including the following meta tag in the document <head>

<meta charset="utf-8">

Exclude Characters (V1)

To exclude certain characters from being replaced by twemoji.js, call twemoji.parse() with a callback, returning false for the specific unicode icon. For example:

twemoji.parse(document.body, {
    callback: function(icon, options, variant) {
        switch ( icon ) {
            case 'a9':      // © copyright
            case 'ae':      // ® registered trademark
            case '2122':    // ™ trademark
                return false;
        return ''.concat(options.base, options.size, '/', icon, options.ext);

Legacy API (V1)

If you're still using our V1 API, you can read our legacy documentation here.

Attribution Requirements

As an open source project, attribution is critical from a legal, practical and motivational perspective in our opinion. The graphics are licensed under the CC-BY 4.0 which has a pretty good guide on best practices for attribution.

However, we consider the guide a bit onerous and as a project, will accept a mention in a project README or an 'About' section or footer on a website. In mobile applications, a common place would be in the Settings/About section (for example, see the mobile Twitter application Settings->About->Legal section). We would consider a mention in the HTML/JS source sufficient also.

The goal of this project is to simply provide emoji for everyone. We definitely welcome improvements and fixes, but we may not merge every pull request suggested by the community due to the simple nature of the project.

Thank you to all of our contributors.
