An enhanced HTML 5 file input for Bootstrap 3.x with file preview for various files, offers multiple selection, and more. The plugin allows you a simple way to setup an advanced file picker/upload control built to work specially with Bootstrap CSS3 styles. It enhances the file input functionality further, by offering support to preview a wide variety of files i.e. images, text, html, video, audio, flash, and objects. In addition, it includes AJAX based uploads, dragging & dropping files, viewing upload progress, and selectively previewing, adding, or deleting files.

Documentation and Demo

  1. Bootstrap 3.x
  2. Latest JQuery
  3. Most modern browsers supporting HTML5 (inputs and FileReader API) including CSS3 & JQuery. For Internet Explorer, one must use IE versions 10 and above. IE9 and below will work as a normal file input, and will not support multiple file selection or the HTML 5 FileReader API.
  4. With release 4.0, AJAX uploads are supported. AJAX uploads require that the browser support HTML5 FormData and XHR2 (XMLHttpRequest 2). Most modern browsers support FormData and XHR2. The plugin will automatically degrade to normal form based submission for browsers not supporting AJAX uploads.


Using Bower

You can use the bower package manager to install. Run:

bower install bootstrap-fileinput

Using Composer

You can use the composer package manager to install. Either run:

$ php composer.phar require kartik-v/bootstrap-fileinput "@dev"

or add:

"kartik-v/bootstrap-fileinput": "@dev"

to your composer.json file

Manual Install

You can also manually install the plugin easily to your project. Just download the source ZIP or TAR ball and extract the plugin assets (css and js folders) into your project.


Step 1: Load the following assets in your header.

<link href="" rel="stylesheet">
<link href="path/to/css/fileinput.min.css" media="all" rel="stylesheet" type="text/css" />
<script src="//"></script>
<!-- canvas-to-blob.min.js is only needed if you wish to resize images before upload.
     This must be loaded before fileinput.min.js -->
<script src="path/to/js/plugins/canvas-to-blob.min.js" type="text/javascript"></script>
<script src="path/to/js/fileinput.min.js"></script>
<!-- bootstrap.js below is only needed if you wish to the feature of viewing details
     of text file preview via modal dialog -->
<script src="" type="text/javascript"></script>
<!-- optionally if you need translation for your language then include 
    locale file as mentioned below -->
<script src="path/to/js/fileinput_locale_<lang>.js"></script>

If you noticed, you need to load the jquery.min.js and bootstrap.min.css in addition to the fileinput.min.css and fileinput.min.js. The locale file fileinput_locale_<lang>.js can be optionally included for translating for your language if needed.

NOTE: The canvas-to-blob.min.js file is the source for the JavaScript-Canvas-to-Blob plugin by blueimp. It is required to be loaded before fileinput.js if you wish to use the image resize feature of the bootstrap-fileinput plugin. For ease of access, the plugin source for JavaScript-Canvas-to-Blob is included in the js/plugins folder of this project repository.

Step 2: Initialize the plugin on your page. For example,

// initialize with defaults

// with plugin options
$("#input-id").fileinput({'showUpload':false, 'previewFileType':'any'});

The #input-id is the identifier for the input (e.g. type = file) on your page, which is hidden automatically by the plugin.

Alternatively, you can directly call the plugin options by setting data attributes to your input field.

<input id="input-id" type="file" class="file" data-preview-file-type="text" >
