+# JavaScript Canvas to Blob
+
+## Description
+Canvas to Blob is a polyfill for the standard JavaScript
+[canvas.toBlob](http://www.w3.org/TR/html5/scripting-1.html#dom-canvas-toblob)
+method.
+
+It can be used to create
+[Blob](https://developer.mozilla.org/en-US/docs/Web/API/Blob)
+objects from an HTML
+[canvas](https://developer.mozilla.org/en-US/docs/HTML/Canvas) element.
+
+## Usage
+Include the (minified) JavaScript Canvas to Blob script in your HTML markup:
+
+```html
+<script src="js/canvas-to-blob.min.js"></script>
+```
+
+Then use the *canvas.toBlob()* method in the same way as the native
+implementation:
+
+```js
+var canvas = document.createElement('canvas');
+/* ... your canvas manipulations ... */
+if (canvas.toBlob) {
+    canvas.toBlob(
+        function (blob) {
+            // Do something with the blob object,
+            // e.g. creating a multipart form for file uploads:
+            var formData = new FormData();
+            formData.append('file', blob, fileName);
+            /* ... */
+        },
+        'image/jpeg'
+    );
+}
+```
+
+## Requirements
+The JavaScript Canvas to Blob function has zero dependencies.
+
+However, Canvas to Blob is a very suitable complement to the
+[JavaScript Load Image](https://github.com/blueimp/JavaScript-Load-Image)
+function.
+
+## API
+In addition to the **canvas.toBlob** polyfill, the JavaScript Canvas to Blob
+script provides one additional function called **dataURLtoBlob**, which is added
+to the global window object, unless the library is loaded via a module loader
+like RequireJS, Browserify or webpack:
+
+```js
+// 80x60px GIF image (color black, base64 data):
+var b64Data = 'R0lGODdhUAA8AIABAAAAAP///ywAAAAAUAA8AAACS4SPqcvtD6' +
+        'OctNqLs968+w+G4kiW5omm6sq27gvH8kzX9o3n+s73/g8MCofE' +
+        'ovGITCqXzKbzCY1Kp9Sq9YrNarfcrvcLDovH5PKsAAA7',
+    imageUrl = 'data:image/gif;base64,' + b64Data,
+    blob = window.dataURLtoBlob && window.dataURLtoBlob(imageUrl);
+```
+
