HTML5 can generally be used as an alternative to Adobe Flash. Both include features for playing audio and video within web pages. It can also be used to play some basic HTML5 browser games and integrated vector graphics made possible with both.
"HTML5" in this article sometimes refers not only to the HTML5 specification, which does not itself define how to do animation and interactivity in web pages, but for HTML5 and related standards such as JavaScript or CSS 3. Animation through JavaScript is also possible with HTML 4.

The table below compares the features of the Flash platform, HTML5 specifications, and features that are implemented in modern web browsers.
Note
- ^ Allows text to overflow to another text box, useful for desktop publishing.
- ^ Static text created through the Flash editor is automatically embedded and anti-alias. Text fields created through ActionScript need to be manually pinned for anti-aliasing to work.

Software support
Flash
The web browser can not render itself Flash media. Instead, Flash is primarily provided through the exclusive Adobe Flash Player, but freely available. Until 2008, no official specifications were used to create alternative players. Alternate players have been developed before 2008, but they support Flash to a lower level than the official one.
The latest version of Adobe Flash Player runs on Microsoft Windows, Apple macOS, RIM, QNX, and Google TV.
The previous version runs on Android 2.2-4.0.x (Flash has been released for 4.0, but Adobe announced that it will stop support for Android 4.1 and higher.) (Flash 11.2), GNU/Linux (Flash 11.2, except for Pepper Flash managed and distributed by Google, not Adobe), PlayStation 3 (Flash 9), PSP (Flash 6). Adobe Flash Lite runs on Wii, Symbian, Maemo Linux, Windows Mobile, and Chumby.
Apple does not allow Flash to run on iOS, the operating system running on iPad, iPhone, iPod Touch and Apple TV. Apple stated that he had no plans to do so.
In February 2012, Adobe announced it would stop developing Flash Player in Linux for all browsers, except Google Chrome, by dropping support for NPAPI and using only Chrome PPAPI. In August 2016, Adobe announced that, starting with version 24, Adobe will continue to offer Flash Player for Linux for other browsers.
HTML5
All web browsers support HTML and other Web standards up to various levels. Adobe released a tool that converts Flash to HTML5, and in June 2011, Google released an experimental tool that does the same thing.
As of December 2013, browser versions like Chrome, Firefox, Internet Explorer, Opera, and Safari apply HTML5 to some extent. However, some parts of the HTML5 specification are still implemented by the browser manufacturer.
Starting January 2015, YouTube defaults to HTML5 player to support more devices better.
Supplier neutrality
Until 2008, the use of Flash was covered by a limiting license. Conditions are prohibited from using specifications to develop any software (including players) that can create or read (and thus convert) SWF files, and require SWF output files to be compatible with Adobe player.
In 2008, restrictions on the use of SWF and FLV/F4V specifications were dropped, and some specifications were released. However, the "File Format SWF Version Specification 10" allegedly does not contain all the required information, does not contain much information that has not been previously known by the community, and itself can not be copied, printed in more than one copy, distributed, resold or translated , without the express written consent of Adobe Systems Incorporated.
Flash is not an open standard. It's controlled by one company, Adobe Systems. In contrast, HTML5 is controlled largely by committees, the Web Application Technology Working Group Hypertext (WHATWG).
Various people praised Flash over the years for consistently displaying platforms. Creating sites in Flash is a way to prevent the ignition of code, where different versions of a site are created for different browsers.
Speaking at 'Adobe Max' in 2011, Itai Asseo also said that, unlike HTML5, Flash offers a way to develop applications that work across platforms. HTML5, he says, is currently applied differently (if any) by various browsers. Although Flash browser plugins are not supported on the Apple iPhone OS, Flash apps can be exported to Adobe AIR, which runs on the operating system as native apps. In the same conversation, Mr. Asseo regretted the return of another browser war (as seen in the late 1990s). If Flash is not favored, he says, web developers need to develop many different versions of their original websites and apps to consider various HTML5 implementations, deny access to browsers that do not support their HTML version, or dramatically reduce the functionality of their sites to send content to the browser the most sophisticated.
Writing
Building a Flash website using Adobe tools is relatively easier than an integrated development environment for CSS, HTML and JavaScript; However, many Adobe tools are expensive and proprietary software.
Tools for HTML5 just started to enter the market; Meanwhile, Adobe has released the first version of the Flash-to-HTML5 conversion tool for existing content and works to create new tools for HTML5 as well, such as Adobe Edge.
Because HTML5 is an open format, tools like that for Flash can also be created for it. Apps like Hype and Adobe Edge are already on the market.
Performance
Flash has a better performance than HTML, as Flash comparisons with HTML in Flash are listed in 2010 as faster than other technologies, when used for non-video animations, even though they are catching up.
Some users, many more using macOS and Linux, complain about the relatively high usage of the Flash CPU for video playback. This is in part because Flash plugins do not use GPUs to render videos. Adobe has responded to some of these criticisms in the 10.1 and 10.2 releases of the Flash plugin by unpacking H.264 video decoding to special hardware and by introducing a new video API called Video Stage. The use of newer ActionScript 3.0 in Flash movies, rather than the older ActionScript 2.0, increases code execution speed by a factor of about 10. Software routines written by developers can also affect the performance of Flash-built applications, reasons that will affect such HTML5 animations too.
Features
Flash has the ability to define measurements in sub-pixel increments. This can result in a sharper and generally more fun view of the Flash website. When confronted with CSS and HTML measurements on a sub-pixel scale, the web browser will be rounded up or down, depending on the browser, leading to inconsistencies and unreliable in the page view.
Flash offers webcam support, while HTML and related technologies were not until recently.
However, there are people who attempt to add "device support" (API devices) to the HTML5 specification, which will allow for video conferencing, access to webcam, microphone, USB-thumbdrives and other USB or serial devices.
DRM
Flash includes DRM support.
HTML5 does not include any digital restriction management functionality. Implementation can support DRM beyond the scope of HTML, for example in codecs. Proposals for adding DRM features to HTML5 itself have been criticized by those who regard the vendor's openness and neutrality (both server-side and client-side) one of the most important properties of HTML, since DRM is not compatible with free software, and in the proposed form potentially no more vendor-neutral than proprietary plug-ins such as Flash.
Accessibility
Both Flash and HTML text can be read by screen readers. However, special care must be taken to ensure the Flash movie is read correctly. For example, if a Flash movie is set to repeat indefinitely, this can cause the screen reader to repeat the content non-stop. Selecting the "Create accessible objects" checkbox in Adobe Flash Professional will create a text-only version of the object for screen readers. It will also hide any movement from the screen reader. Because Flash content is usually placed on a single webpage, the content appears as a single entry on search engine results pages, except techniques like deep links are used with libraries like SWFAddress to provide multiple links within Flash websites and web apps. Widgets of user interfaces in Flash objects do not always behave like their native host counterparts. The keyboard, mouse, and other accessibility shortcuts may not work unless the web page developer explicitly adds support for them.
Search engine
Flash content and HTML content can be indexed by Google, Yahoo !, and Bing, although two-way text (eg Arabic, Hebrew) is not supported by Google. Yahoo! added support for indexing Flash sites in 2008, even though Google had been able to index it for several years before that. Bing added support for Flash sites in 2010.
iOS devices
Apple has promoted HTML5 as an alternative to Flash for videos and other content on iOS, citing performance reasons for not allowing Adobe Flash Player to be installed on iOS devices, including iPhone, iPod touch and iPad. Flash apps can be packaged as native iOS apps through Adobe Integrated Runtime and iOS Packager.
