Features

  • Multiple file upload:

  • Drag & Drop support:
    Allows to upload files by dragging them from your desktop or file manager and
    dropping them on your browser window.
  • Upload progress bar:
    Shows a progress bar indicating the upload progress for individual files and
    for all uploads combined.
  • Cancelable uploads:
    Individual file uploads can be canceled to stop the upload progress.
  • Resumable uploads:
    Aborted uploads can be resumed with browsers supporting the Blob API.
  • Chunked uploads:
    Large files can be uploaded in smaller chunks with browsers supporting the
    Blob API.
  • Client-side image resizing:
    Images can be automatically resized on client-side with browsers supporting
    the required JS APIs.
  • Preview images, audio and video:
    A preview of image, audio and video files can be displayed before uploading
    with browsers supporting the required APIs.
  • No browser plugins (e.g. Adobe Flash) required:
    The implementation is based on open standards like HTML5 and JavaScript and
    requires no additional browser plugins.
  • Graceful fallback for legacy browsers:
    Uploads files via XMLHttpRequests if supported and uses iframes as fallback
    for legacy browsers.
  • HTML file upload form fallback:
    Allows progressive enhancement by using a standard HTML file upload form as
    widget element.
  • Cross-site file uploads:
    Supports uploading files to a different domain with cross-site XMLHttpRequests
    or iframe redirects.
  • Multiple plugin instances:
    Allows to use multiple plugin instances on the same webpage.
  • Customizable and extensible:
    Provides an API to set individual options and define callback methods for
    various upload events.
  • Multipart and file contents stream uploads:
    Files can be uploaded as standard “multipart/form-data” or file contents
    stream (HTTP PUT file upload).
  • Compatible with any server-side application platform:
    Works with any server-side platform (PHP, Python, Ruby on Rails, Java,
    Node.js, Go etc.) that supports standard HTML form file uploads.

fixed vulnerabilities

Please also read the SECURITY document for instructions on how to
securely configure your Web server for file uploads.

Setup

jQuery File Upload can be installed via NPM:

npm install blueimp-file-upload

This allows you to include jquery.fileupload.js and
its extensions via node_modules, e.g:

<script src="node_modules/blueimp-file-upload/js/jquery.fileupload.js"></script>

The widget can then be initialized on a file upload form the following way:

$('#fileupload').fileupload();

Requirements

Mandatory requirements

Optional requirements

Cross-domain requirements

Cross-domain File Uploads
using the
Iframe Transport plugin
require a redirect back to the origin server to retrieve the upload results. The
example implementation
makes use of
result.html
as a static redirect page for the origin server.

The repository also includes the
jQuery XDomainRequest Transport plugin,
which enables limited cross-domain AJAX requests in Microsoft Internet Explorer
8 and 9 (IE 10 supports cross-domain XHR requests).
The XDomainRequest object allows GET and POST requests only and doesn’t support
file uploads. It is used on the
Demo to delete uploaded files
from the cross-domain demo file upload service.
