Run Windows Desktops and Applications in Any HTML5 Browser

Access virtual workspaces from anywhere using the Parallels® Web Client. Enable fast access without complex installation or manual setup.

Flexible web-based access to business resources

Parallels RAS (Remote Application Server) enables web access to applications, data, and desktops from any HTML5 browser, on a desktop or mobile device, anywhere—without needing to install a client.

The Parallels User Portal can be used to launch applications with a platform-specific Parallels Client and can both detect the Client and install it if required.

Bidirectional support

Parallels RAS provides drag-and-drop functionality. Local files can be dragged and dropped to published resources opened in HTML5 browsers. It's possible to upload and download files from local devices to remote locations and vice versa.

With bidirectional audio, IT administrators can enable the sound input and output redirection from the local device to remote applications. Microphone redirection enables the endpoint microphone to be used in the remote resource.


With white-labeling, personalization is straightforward. Customize the Web Client with a corporate color scheme and logo and enable corporate branding on all HTML5 browsers.

Different themes can be configured for individual users and groups within the active directory to reflect different departments within companies.

Easy printing

The Parallels Web Client enables employees to immediately use any printer connected to the local machine.

With Parallels RAS, printer redirection is quick and easy—there is no need to install local drivers with Parallels RAS Universal Printing capabilities.

HTML5 auto-login

Decrease login times and enable users to quickly access apps and resources. With automatic login, the end-user does not have to re-input credentials as soon as the Parallels User Portal is opened.

End users may be asked to enable auto-login which can later be managed from the Web Client settings or centrally controlled by administrators from Parallels RAS policies.

Remote working simplified

Quickly implement bring your own device (BYOD), choose your own device (CYOD), and other remote working initiatives via virtual desktops and applications on any HTML5 browser.

Keep users' productivity high by providing the same workspace experience regardless of device used.
