The Ultimate Guide to Embedding HTML in Digital Signage

Digital signage has become a go-to solution for modern communication in businesses, schools, clinics, and beyond. Whether it’s displaying daily announcements in a school hallway, showcasing wait times at a medical clinic, or running a live dashboard in a busy office, digital screens are now a powerful part of everyday operations. As the demand for up-to-date and engaging content grows, so does the need for flexible tools that keep things simple.

That’s where HTML comes in. By embedding custom HTML, you can take your digital signage to the next level—showing real-time data, interactive tools, live websites, calendars, dashboards, and more. It’s fast, efficient, and fully customizable to suit your needs.

And with Juuno’s Embed Anything app, it’s never been easier. Just paste a URL or embed code, and your screen will display live, dynamic content. It’s the easiest way to turn a smart TV into a powerful, live digital sign in minutes.

How does HTML come into play with digital signage?

HTML (HyperText Markup Language) is the standard language used to create and structure content on the web, and it plays a big role in digital signage too. In the context of digital signage, HTML lets you display live, interactive, and real-time content directly on your screens. Instead of uploading static images or pre-made slides, HTML-based content can change on the fly, respond to user interaction, or update automatically based on live data.

The key difference between static and HTML-based signage is flexibility. Static content—like images or PDFs—never changes unless you manually update it. HTML content, on the other hand, can display live dashboards, up-to-date calendars, booking systems, web forms, and even embedded apps.

This opens the door to all kinds of use cases: showing Google Calendars in waiting rooms, dashboards in corporate offices, forms for check-ins, or news widgets in school hallways. With HTML, your signage becomes smarter, more useful, and always up to date.

Why use HTML for digital signage?

Using HTML for digital signage gives you the freedom to display live, interactive content that updates automatically, with no design team needed. It’s a smart, cost-effective way to keep your screens fresh, engaging, and relevant.

• Dynamic content: Easily show real-time data like sales dashboards, booking calendars, weather updates, news feeds, and more.

• Interactivity: Ideal for kiosks and touchscreen displays where users can interact with menus, maps, or forms.

• Customization: Tailor your screen layout, fonts, colors, and content to match your brand without relying on expensive design tools.

• Low-cost, high-flexibility: Skip the pricey media players. Just use any smart TV or browser-enabled device to run your signage.

How to embed HTML into digital signage

Embedding HTML into your digital signage setup is easier than you might think, and it opens the door to rich, real-time content that goes far beyond static slides. Whether you're showing a dashboard, booking tool, or live website, follow these simple steps to get started.

Step 1: Choose a digital signage platform that supports HTML

Before you can embed HTML, you’ll need to pick a signage platform that makes it possible. Not all software supports HTML embedding, so it's important to choose one that gives you the flexibility you need, without complicating things.

Here’s what to look for:

• Browser-based setup: Choose a platform that runs directly in a web browser, like Juuno, so you don’t need any special hardware.

• Supports iFrames or raw HTML: Make sure the platform allows you to embed custom HTML or iFrame code for full control over what displays.

• Widget and app compatibility: Look for tools that let you add widgets like weather, calendars, forms, or dashboards with ease.

Juuno makes this process incredibly simple—just use a smart TV with a built-in browser. No media players. No complicated setup. Just plug in, log in, and start displaying beautiful, live content.

Step 2: Source or write your HTML

Once you’ve chosen your digital signage platform, the next step is to source or write your HTML content. You don’t need to be a developer to get started. In fact, many tools you already use can be easily embedded into your signage using simple HTML or iframe code.

For example, you can publish a Google Slides presentation to the web and embed it to display announcements or updates that are easy to change anytime. Notion pages also work well, especially for internal communications or visual checklists. Just make the page public and grab the link. If you want to display live metrics or KPIs, tools like Databox or Google Data Studio allow you to embed real-time dashboards that keep your team informed at a glance.

Of course, if you do have access to basic HTML skills (or even just a little curiosity), you can write your own HTML pages with custom layouts, branding, and widgets. Don’t worry if you're not an expert—ChatGPT can help you create or clean up embed code so it displays correctly on your screen. Whether you’re using drag-and-drop tools or custom code, the key is to make sure your content is responsive, clean, and easy to update.

Step 3: Use embed code in the platform

Now that you’ve sourced your HTML content, it’s time to embed it into your digital signage platform. Most platforms that support HTML will give you a place to paste your embed code—typically using an iframe. An embed code looks like this:
<iframe src="https://yourlink.com" width="100%" height="100%" frameborder="0"></iframe>.
This simple tag allows you to display external content like websites, tools, or dashboards directly on your screen.

To make sure your content looks great on any screen, it’s important to set your width and height to 100%. This ensures the content stretches to fill the available space and adapts to different resolutions. If you're embedding content designed for desktop, double-check that it’s mobile-responsive so it doesn't get cut off or look too small.

Step 4: Schedule and preview your HTML content

Once your HTML content is embedded, it’s time to schedule and preview it to ensure everything runs smoothly. Most digital signage platforms like Juuno let you organize your content into playlists and assign them to specific time slots or days of the week. For example, you might want your Google Calendar to display during office hours, a dashboard in the mornings, and an inspirational quote slideshow in the afternoons. With Juuno, you can easily drag and drop content into a playlist and assign it to different screens or times, all from one centralized dashboard.

Before going live, it’s crucial to preview your content. This helps you catch any display issues like stretched layouts or content not loading properly. If your HTML isn’t showing up, common issues include cross-domain restrictions (some sites don’t allow their pages to be embedded) or a missing https:// in your embed code, which is required for most platforms.

Always run a full screen test using the same browser and device that will be used for the actual signage. This way, you can ensure everything looks and behaves exactly as expected. A few minutes of testing can save hours of troubleshooting later—and helps keep your signage looking sharp and professional.
