An iFrame or inline frame is an HTML element that lets the website load another HTML page within the document. In simple words, an extra page gets loaded on the parent page.

You can understand this with a few examples, such as the advertisements, embedded videos, web analytics, and other interactive content that you see on a web page. Basically, a parent page lets all these page layers appear on top of it.

The iFrame is supported by all major web browsers. Notably, when a browser encounters an iFrame, it creates a new HTML document to load it within the web page.

The name Inline Frame comes from the fact that to the user, all content is available on a single page. Moreover, the iFrame loads its own JavaScript and CSS separate from the parent frame.

This means that you can interact with the child iFrame, refresh it, or even change the size and position of the child iFrame within the parent iFrame.

However, web page administrators are advised not to use more than one iFrame because they require additional memory and processing power, which may cause the website to crash or load pages very slowly.

In this guide, we will give a list of browsers that support iFrame. Let us get right into it.

Do iFrames work on all browsers?

Yes, all modern web browsers support iFrame since it’s included in the latest HTML5. Google Chrome being the father of Chromium browsers support iFrame.

Other Chromium browsers also support iFrame. The ability is called lazy loading of iFrame content in Chrome and other Chromium-based browsers.

This new feature lets you properly balance the loading speed of the web page by scheduling the loading of web content.

A web browser that supports iFrame will let you embed a YouTube video or Google Maps content on a web page. Web analytics tools also make use of the iframes that are hidden to monitor the user without them noticing.

In short, all modern desktop and smartphone browsers support iFrame, but not all of them are capable of responding to the new attributes from HTML5.

Does HTML5 support iFrame?

Yes. HTML5 supports iFrame or inline frame. In fact, the iFrame is the only type of frame allowed in HTML5. The <iframe> element is still valid in HTML5.

HTML uses the <iframe> tag to specify an inline frame, or as referred to in HTML5, a nested browsing context. Let us go through the list of the best browsers that support iFrame. </p>

Is iFrame a bad practice?

Well, there is no straight answer to this question. Notably, if you are using an iFrame on a properly developed site, then that is a bad practice. However, sometimes, you can get away with it.

The reason for considering it as a bad practice is the fact that iFrames are now getting abused as well. It shouldn’t be used as an integral part of the website, but just as a piece of content within a site.

Moreover, using iFrame content doesn’t make your website more or less secure than other websites. So, web admins should be very careful in selecting an iFrame that is trusted and reliable.

What disadvantages does using iFrames involves?

Some of the disadvantages of iFrames are:

  • It is memory and processor extensive
  • There is no control over third-party websites

  • iFrame could phish your user’s data without your knowledge, by adding a submittable form.
  • Could run a malicious plug-in
  • Change the source of the URL
  • Often breaks the browser’s back button
  • May suddenly open an iFrame content in a new browser window
  • Navigation of websites stops because of malicious iFrame

One of the major impacts that iFrames could cause is SEO problems. Besides, Google has clearly stated at their Webmasters Help Forum:

IFrames are sometimes used to display content on web pages. Content displayed via iFrames may not be indexed and available to appear in Google’s search results. We recommend that you avoid the use of iFrames to display content. If you do include iFrames, make sure to provide additional text-based links to the content they display, so that Googlebot can crawl and index this content.

What replaced iFrames?

You can use embed tag as an alternative to iFrames. Because of the fact that embed tag is used for the same purpose as the iFrame, and has some advantages over it such as letting you embed various external resources in a web page, embed media like PDF, image, audio, video, etc. embed tag is widely used in place of iFrames.

Moreover, embed tag is supported by all major browsers including Google Chrome, Internet Explorer, Microsoft Edge, Mozilla Firefox, Apple Safari, and Opera browser.

What can I use instead of iFrames in HTML5?

The list mentions all the alternatives that you can use instead of iFrames in HTML5:

  • Object tag: Lets you embed multimedia components and even set the height and width of the container.
  • Embed tag: Lets you embed media like PDF, image, audio, video, and web pages. It can also set the height and width attributes of the container like the Object tag.
