The  lt input type file gt  element does not by default work with the ng-model directive  It needs a custom directive  Working Demo of select-ng-files Directive that Works with ng-model1  x000D   x000D  angular module  app        angular module  app   directive  selectNgFiles   function       return       require   ngModel       link  function postLink scope elem attrs ngModel          elem on  change   function e            var files   elem 0  files          ngModel  setViewValue files                          x000D   lt script src    unpkg com angular angular js  gt  lt  script gt     lt body ng-app  app  gt       lt h1 gt AngularJS Input  type file  Demo lt  h1 gt            lt input type  file  select-ng-files ng-model  fileList  multiple gt            lt h2 gt Files lt  h2 gt       lt div ng-repeat  file in fileList  gt          file name        lt  div gt     lt  body gt  x000D   x000D   x000D     http post from a FileList  scope upload   function url  fileList        var config     headers     Content-Type   undefined                       transformResponse  angular identity                         var promises   fileList map function file            return  http post url  file  config               return  q all promises       When sending a POST with a File object  it is important to set  Content-Type   undefined  The XHR send method will then detect the File object and automatically set the content type

I am able to upload files using AngularJS by using below code   The file for the argument that needs to be passed for the function ngUploadFileUpload is  scope file as per your question   The key point here is to use transformRequest      This will prevent  http with messing with the contents of the file           function getFileBuffer file                var deferred   new  q defer                var reader   new FileReader                reader onloadend   function  e                    deferred resolve e target result                             reader onerror   function  e                    deferred reject e target error                              reader readAsArrayBuffer file               return deferred promise                     function ngUploadFileUpload endPointUrl  file                 var deferred   new  q defer                getFileBuffer file  then function  arrayBuffer                      http                       method   POST                       url  endPointUrl                      headers                             accept    application json odata verbose                            X-RequestDigest   spContext securityValidation                           content-length   arrayBuffer byteLength                                            data  arrayBuffer                      transformRequest                        then function  data                        deferred resolve data                      function  error                        deferred reject error                       console error  Error   error                                     function  error                    console error  Error   error                               return deferred promise

You can achieve nice file and folder upload using flow js   https   github com flowjs ng-flow  Check out a demo here  http   flowjs github io ng-flow   It doesn t support IE7  IE8  IE9  so you ll eventually have to use a compatibility layer  https   github com flowjs fusty-flow js

I tried all alternatives that  Anoyz  Correct answer  gives    and the best solution is https   github com danialfarid angular-file-upload  Some Features    Progress Multifiles Fields  Old browsers  IE8-9    It s work fine for me  You just have to pay attention to instructions   In server-side i use NodeJs  Express 4 and Multer middleware to manage multipart request

Some of the answers here propose using FormData    but unfortunately that is a browser object not available in Internet Explorer 9 and below  If you need to support those older browsers  you will need a backup strategy such as using  lt iframe gt  or Flash   There are already many Angular js modules to perform file uploading   These two have explicit support for older browsers    https   github com leon angular-upload - uses iframes as a fallback https   github com danialfarid ng-file-upload - uses FileAPI Flash as a fallback   And some other options    https   github com nervgh angular-file-upload  https   github com uor angular-file https   github com twilson63 ngUpload https   github com uploadcare angular-uploadcare   One of these should fit your project  or may give you some insight into how to code it yourself

You may consider IaaS for file upload  such as Uploadcare  There is an Angular package for it  https   github com uploadcare angular-uploadcare  Technically it s implemented as a directive  providing different options for uploading  and manipulations for uploaded images within the widget    lt uploadcare-widget   ng-model  object image info uuid    data-public-key  YOURKEYHERE    data-locale  en    data-tabs  file url    data-images-only  true    data-path-value  true    data-preview-step  true    data-clearable  true    data-multiple  false    data-crop  400 200    on-upload-complete  onUCUploadComplete info     on-widget-ready  onUCWidgetReady widget     value     object image info cdnUrl        gt    More configuration options to play with  https   uploadcare com widget configure

i think this is the angular file upload   ng-file-upload  Lightweight Angular JS directive to upload files   Here is the DEMO page Features   Supports upload progress  cancel abort upload while in progress  File drag and drop  html5   Directory drag and drop  webkit   CORS  PUT html5  POST methods  validation of file type and size  show preview of selected images audio videos  Cross browser file upload and FileReader  HTML5 and non-HTML5  with Flash polyfill FileAPI  Allows client side validation modification before uploading the file Direct upload to db services CouchDB  imgur  etc    with file s content type using Upload http    This enables progress event for angular http POST PUT requests  Seperate shim file  FileAPI files are loaded on demand for non-HTML5 code meaning no extra load code if you just need HTML5 support  Lightweight using regular  http to upload  with shim for non-HTML5 browsers  so all angular  http features are available   https   github com danialfarid ng-file-upload
