Connect Browser Plug-in

The Aspera Connect Browser Plug-in is a self-installing web browser plug-in that powers high-speed uploads and downloads with the Aspera Connect Server, also enabling web-based transfers for Aspera web application faspexTM and Shares. Compatible with most standard browsers and sporting a very light system footprint, Aspera Connect integrates all of Aspera’s high-performance transport technology in a small, easy-to-use package that provides unequaled control over transfer parameters.

Use Cases

Browser-based file transfers

Enable teams, customers and partners to easily transfer files and directories at high speed to and from your Aspera servers via any web browser. Without any software to download and install, users can transfer data via any computer, at any time, over any connection (WAN, satellite, wireless).

Product Highlights

Localized Languages

The latest version of our Web browser plug-in now supports Simplified Chinese, Japanese, French, and Spanish in addition to English. The high-speed transfer plug-in automatically sets the language based on your system's language settings.

Lightweight and browser-independent

Aspera Connect will install and launch automatically when a web application such as Aspera Shares initiates FASP® transfers. The transfers are performed independent of the browser, without locking the page during the transfer, so that users can continue working.

Reliable and secure

With built-in automatic resume of partial transfers and retry of failed transfers, Aspera Connect assures that critical files make it across the network on time and intact. All files can be encrypted in transfer and at rest, ensuring security of digital assets, without compromising transfer speeds.

Real-time transfer monitoring and control

An easy-to-use interface provides real-time status of transfer progress and transfer rate, allowing users to adjust transfer rates on the fly and to cancel/pause/resume queued transfers.


Aspera’s Connect SDK allows developers to easily integrate Aspera file transfer capabilities into their web applications with complete control over branding and the end-user experience. From installation to delivery, Aspera Connect SDK gives developers full control over how Aspera file transfer capabilities are exposed to their end-users with an "in-browser" user experience. By leveraging the JavaScript APIs, developers are able to control both the look and feel and workflow of transfer initiation, transfer progress, transfer control (such as pause, resume, cancel, etc.), error handling, and full control over transfer parameters.

Unrivaled Aspera performance

  • Powered by Aspera’s patented FASP® transport technology, content is sent at high speed, regardless of file sizes, transfer distances or network conditions.
  • Precise bandwidth control ensures the entire allocated bandwidth is utilized to achieve maximum transfer speeds, while remaining fair to other business-critical network traffic.
  • 100% reliable data delivery with auto resume of failed or incomplete transfers.
  • Real-time reporting of transfer progress and performance.
  • Automatic, fast and lossless inline compression reduces data set transfer sizes, providing further boost to Aspera's industry-leading transfer performance.
  • Ability to switch to slower HTTP-based transfers for highly restrictive network environments.

Simple, lightweight plug-in

  • A simple plug-in that installs and launches automatically within the browser, as needed by the web application.
  • Connect Browser Plug-in 3.6 is available with new “plug-in-less” architecture.
  • Transfers happen independent of the browser, so that users can continue their work uninterrupted.
  • Easy-to-use interface provides real-time visual monitoring of transfer progress and queued packages.
  • Ability to adjust bandwidth utilization on the fly is ideal for boosting transfer speeds for time-critical content or throttling down less important transfers to leave bandwidth for other business-critical network traffic (e.g. video conferencing)
  • Automatic UI language selection, based on operating system language setting, supports English, Spanish, French, Japanese and Simplified Chinese, providing an easy-to-understand interface during installation and use.

Bullet-proof security

Keep your business-critical digital assets safe with Aspera’s enterprise-grade security features.

  • Through SSH authentication establishes secure connections between the plug-in and the transfer server.
  • AES-128 data encryption in transit and at rest ensures that files are accessible only to those with the right password to decrypt them.
  • FIPS 140-2 compliant cryptographic module provides strong encryption that is accredited by the US Government.
  • Data integrity verification for each transmitted block guards against man-in-the-middle attacks and attempts at data or content theft.
