 Run `grunt wkhtmltopdf` to execute all the targets or `grunt wkhtmltopdf:targetname` to execute a specific target. Every `html` file defined by the `src` parameter will be turned into a PDF and saved to `dest` folder.
 
+### Sending arguments to `wkhtml2pdf`
+
+Arguments sent via the `args` key in the task definition will be forwarded to `wkhtml2pdf` as follow :
+
+```javascript
+    //...
+    wkhtmltopdf: {
+      prod: {
+        src: 'path/to/some/html/file/*.html',
+        dest: 'pdf/output/',
+        args: [
+          '--dpi', '96',
+          '--print-media-type',
+          '--grayscale'
+        ]
+      }
+    },
+    //...
+```
+
+Defining custom arguments will override default ones:
+
+```javascript
+// grunt-wkhtml2pdf default arguments
+var args = [
+  '--dpi', '96',
+  '--print-media-type'
+]
+```
+
+See [wkhtml2pdf documentation][wkhtmltopdf_doc] for available options
