Supported Web Browsers

TinyMCE uses advanced JavaScript techniques to normalize inconsistencies among browsers to ensure a uniform user experience. The primary focus is on:

  • Google Chrome

  • Mozilla Firefox

  • Microsoft Edge

  • Microsoft Internet Explorer

  • Apple Safari

TinyMCE may not function as expected on unlisted browsers. Try out the TinyMCE examples on to determine any functional limitations of an unlisted browser.

Browser Windows Mac GNU/Linux






IE 11






TinyMCE does not support browsers running in Quirks or backward compatibility modes.

TinyMCE supports the most recent version of all browsers listed above. TinyMCE also supports the latest Extended Support Release (ESR) from each vendor (e.g. Firefox). TinyMCE provides support for the prior major version for 60 days after the release has been superseded by a new major version (e.g. Chrome 71 vs. Chrome 72).

Supported Mobile Platforms

TinyMCE mobile is available in TinyMCE versions 4.7+ and 5.

TinyMCE mobile is designed to run on iOS Safari and Android Chrome. TinyMCE mobile is tested on the following platforms:

OS Browser Device

Android 10


Mobile phone

Android 11


Mobile phone

iOS/iPadOS 13



iOS/iPadOS 14



Visit TinyMCE mobile documentation for information on TinyMCE mobile setup and configuration.

Supported Application Servers: Self-hosted Enterprise

The TinyMCE spell checking server-side component requires a Java Web Application Server that supports Servlet Implementation API 3.0.

Java Development Kit


Java (J2EE) Application Servers

  • Eclipse Jetty:

    • 9.4+

  • WebSphere Application Server (WAS) 8 or later

  • Apache Tomcat:

    • 10 (See note below)

    • 9+

    • 8.5.12+

    • 8.0.42+

    • 7.0.76+

Tomcat 10 will require WAR files to be placed in the webapp-javaee directory rather than the webapps directory due to the change to Jakarta servlets. Jetty 11 is not currently supported due to this change.

Operating Systems

  • Windows Server 2008 SP2

  • Red Hat Enterprise Linux v6

  • Red Hat Enterprise Linux v5

Minimum Hardware Requirements

  • CPU: Dual Core Processor ~ 2Ghz. For higher loads, a quad core or higher is recommended.

HTML Cleaning

On all browsers, PowerPaste provides basic HTML cleaning. For browsers where HTML5 support is not available, PowerPaste uses the browser DOM to import and clean HTML. This mechanism is the primary cleaning method on browsers where HTML5 clipboard APIs are not available. While the resulting content is clean HTML the direct conversion to a browser DOM can result in some loss of content structure and/or formatting information.

Improved HTML Cleaning

On browsers that support HTML5 APIs, PowerPaste is able to use improved HTML cleaning techniques. Improved HTML cleaning uses the HTML5 clipboard APIs to access the clipboard directly. The original document structure and formatting (when importing formatting) is more likely to be preserved. Where available this approach gives the highest fidelity copy and paste from supported applications to HTML.

Image Import

On browsers that support HTML5, PowerPaste is able to import images embedded in the content (e.g. from Microsoft Word) into the editor. These images can then be uploaded via a HTTP post as required.
