Web Browser Support

The Kendo UI widgets and framework components are designed to support all major web browsers and deliver a cross-browser compatibility, standards compliance, and touch-device support.

However, depending on the specifics of your project, the controls you use, and the versions of the widgets, their browser support may vary.

Regular Support

Most Kendo UI widgets have no specific limitations as of the browser versions they support.

Some features may not be available due to browser limitations.

Edge 20 or later (officially supported versions by Microsoft only)
Internet Explorer* 9 or later
Chrome Current and previous
Firefox Current and ESR releases
(What is ESR?)
Opera 15 or later
OS X Safari 6.2.6 or later

Support for Kendo UI Hybrid

The hybrid UI widgets and framework components are intended for Cordova-based deployments and support the mobile device browsers and corresponding web view components listed in the following table.

Internet Explorer 10 or later on Windows Phone 8.x
Chrome Current and previous
Firefox Not supported
OS X Safari 6.2.6 or later

Support for Data Visualizing Widgets

The Kendo UI widgets which render data visualization, such as the Charts, Gauges, Barcodes, Diagrams, and Maps, may require more recent browser versions according to the following table.

Fully supported browsers

Edge 20 or later (officially supported versions by Microsoft only)
Internet Explorer 9 or later
Chrome Current and previous
Firefox Current and ESR releases (What is ESR?)
Opera 15 or later
OS X Safari 6.2.6 or later
iOS Safari iOS 8 or later
Chrome for Mobile 21 or later

Browsers with limited support

Internet Explorer 10 Dashed lines in canvas are not supported, which affects the image export as well
Android 2.x, therefore, uses non-interactive canvas output
Android 2.3 The Canvas rendering mode is only supported

Support for PDF Export

The Kendo UI PDF generator is tested and supported in the following desktop browsers:

  • Internet Explorer 9 and later.
  • Latest Chrome, Firefox, Safari, and Blink-based Opera versions.

Internet Explorer 9 and Safari do not support the PDF-related option for saving files. To enable PDF export, you need to implement a server proxy.

Officially, PDF export is not supported on mobile because of browser limitations and CORS-related security restrictions in hybrid applications. For example, it is not possible to load locally stored font files in hybrid applications. Even though exporting in PDF might work on some mobile devices in specific scenarios, PDF export is not supported in mobile browsers and hybrid mobile applications.

Providing Best Performance

To boost the performance of your project:

  • Always use an up-to-date browser version.
  • Check Disable Script Debugging from your browser configuration options.
  • Activate Caching in Internet Explorer.

Notes on Web Browser Support

  • As of the Kendo UI 2017 R1 release, Internet Explorer 8 is no longer supported.
  • As of the Kendo UI 2015 Q3 release, Internet Explorer 7 is no longer supported.
  • Since Internet Explorer 11 was released in October 2013, look up the Kendo UI 2013 Q3 SP2 (2013.3.1324) release or a more recent Kendo UI version if you need support for it.
  • Browsers in beta stage are not supported.
  • Zoomed-in pages are not supported.
  • Zoomed-out pages are not supported. Different browsers handle sub-pixel calculations differently and zooming out the page may lead to unexpected behavior—for example, missing borders.
  • Exporting a zoomed-in or zoomed-out page to PDF is not supported.
  • Quirks mode is not supported.

    Always specify a DOCTYPE. Recommended DOCTYPEs include HTML5, XHTML 1.1, XHTML 1.0 Strict and HTML4 Strict. The HTML4 Transitional DOCTYPE fires the Quirks mode and should not be used. XHTML 1.0 Transitional works well in most cases, but may cause issues with the vertical positioning of icons. The correct syntax for all DOCTYPEs is provided on the W3C website.

  • Internet Explorer compatibility modes are not supported. These modes can exhibit different behavior and rendering bugs as compared to the browser versions they emulate.

  • Windows Universal apps and Cordova for Windows 10 environments are not supported, due to the sandbox restrictions of the environment. The recommended UI suite for this environment is UI for Windows Universal.
  • Unexpected behaviors that occur only in a hybrid application, but not in a standalone supported browser, are by default considered to be triggered by the hybrid environment and unrelated to Kendo UI.
  • It is highly advisable to use Internet Explorer Edge mode over a META tag or an HTTP header:

    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
  • Kendo UI uses a progressive enhancement for its CSS styling. As a result, old and obsolete browsers may ignore CSS 3 styles such as rounded corners and linear gradients.

  • Internet Explorer behaves differently when embedded inside a desktop (WinForms) application. It reports to support pointer events, but actually does not. As a result, some events, on which Kendo UI relies, are not fired. To handle this issue, execute the following JavaScript code before the Kendo UI scripts are registered.

        window.MSPointerEvent = null;
        window.PointerEvent = null;
