+## `hx-encoding`
+
+The `hx-encoding` attribute allows you to switch the request encoding from the usual `application/x-www-form-urlencoded`
+encoding to `multipart/form-data`, usually to support file uploads in an ajax request.
+
+The value of this attribute should be `multipart/form-data`.
+
+The `hx-encoding` tag may be placed on parent elements.
+
+### Notes
+
+* `hx-encoding` is inherited and can be placed on a parent element

+#### <a name="files"></a> [File Upload](#files)
+
+If you wish to upload files via an htmx request, you can set the [hx-encoding](/attributes/hx-encoding) attribute to 
+`multipart/form-data`.  This will use a `FormData` object to submit the request, which will properly include the file
+in the request.
+
+Note that depending on your server-side technology, you may have to handle requests with this type of body content very 
+differently.
+
+Note that htmx fires a `htmx:xhr:progress` event periodically based on the standard `progress` event during upload, 
+which you can hook into to show the progress of the upload.
