+# Jimp ... in a browser
+
+Browser support for Jimp was added by Phil Seaton. This enabled Jimp to be used in [Electron](http://electron.atom.io/) applications as well as web browsers.
+
+Example usage:
+
+```html
+<script src="jimp.min.js"></script>
+<script>
+  Jimp.read("lenna.png")
+    .then(function (lenna) {
+      lenna
+        .resize(256, 256) // resize
+        .quality(60) // set JPEG quality
+        .greyscale() // set greyscale
+        .getBase64(Jimp.MIME_JPEG, function (err, src) {
+          var img = document.createElement("img");
+          img.setAttribute("src", src);
+          document.body.appendChild(img);
+        });
+    })
+    .catch(function (err) {
+      console.error(err);
+    });
+</script>
+```
+
+See the [main documentation](https://github.com/jimp-dev/jimp) for the full API documenatinon.
+
+## WebWorkers
+
+For better performance, it recommended that Jimp methods are run on a separate thread using [`WebWorkers`](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Using_web_workers). The following shows how using two files (`index.html` and `jimp-worker.js`):
+
+```js
+// index.html
+
+var worker = new Worker("jimp-worker.js");
+worker.onmessage = function (e) {
+  // append a new img element using the base 64 image
+  var img = document.createElement("img");
+  img.setAttribute("src", e.data);
+  document.body.appendChild(img);
+};
+worker.postMessage("lenna.png"); // message the worker thread
+```
+
+```js
+// jimp-worker.js
+
+importScripts("jimp.min.js");
+
+self.addEventListener("message", function (e) {
+  Jimp.read(e.data).then(function (lenna) {
+    lenna
+      .resize(256, 256) // resize
+      .quality(60) // set JPEG quality
+      .greyscale() // set greyscale
+      .getBase64(Jimp.MIME_JPEG, function (err, src) {
+        self.postMessage(src); // message the main thread
+      });
+  });
+});
+```
