01
Stay in the flow
No minimizing, no hunting for the right tab. The live content is already on the slide, so your presentation never breaks stride.
01 — The bridge
The web comes to the slide.
Most rooms still run PowerPoint — and they deserve better than screenshots. SparkEmbed puts a live, interactive web page directly on your slide: dashboards that stay current, demos that stay clickable, all without leaving the presentation. It's the bridge between the deck you have and the medium you're heading toward. Cross it at your own pace.
Yes, you can embed a live website in PowerPoint. SparkSlides Embed is a PowerPoint add-in that loads any web page directly onto a slide so it stays interactive while you present. It works on Windows, Mac, and PowerPoint on the web.
The Web Viewer is gone. Live slides are back.
Put a living web page inside your PowerPoint slide.
Charts that update. Calculators your audience can use. Your own app, running right on the slide. No tab-switching, no breaking the flow of your presentation.
Works on Windows, Mac, and PowerPoint on the web. Built for people who like things that just work, and don't mind a five-minute setup.
Already bought it? Jump to setup →The moment that started this
You know the pause. The one where you leave your slides.
You are presenting, the room is with you, and then you need to show the live thing. The dashboard. The calculator. The prototype. So you minimize PowerPoint, find the browser, wait for the page, and the spell breaks. The audience watches you fumble between windows instead of watching the idea.
For years there was a quiet fix for this. Microsoft's Web Viewer add-in let you drop a live web page straight onto a slide. Then it was retired, and the people who relied on it were left switching windows again, searching for something to replace it and mostly coming up empty.
SparkSlides Embed is that replacement, rebuilt on the modern, supported add-in platform. It does one thing with care: it shows a live, interactive web page on your slide, and keeps it fully usable while you present. Your charts stay current. Your demo stays clickable. Your flow stays unbroken.
"A presentation should not have to stop being a presentation just to show something real."
This page is part story and part manual. First the why, because it changes how you think about a slide. Then the how, step by step, honestly, including the parts that take a little patience. If you have ever wished your slides could do more than sit still, you are in exactly the right place.

Why it changes the room
Three things it does that a screenshot never will
02
Always current
The page loads live every time, so a dashboard or chart shows real numbers as of this moment, not a screenshot from last week.
03
Let them touch it
Hand the audience a working calculator, a configurator, or your actual product, and let them watch it react in real time.
See it, don't take our word
This is a live, interactive embed. Right here on the page.
The box below is a real web tool, running live, exactly the way it would sit on your slide. Click into it and use it. This is the experience your audience gets, without you ever leaving PowerPoint.

Full walkthrough
Watch the complete setup and demo
See the add-in installed, configured, and used in a live presentation — start to finish. Five minutes of watching saves five minutes of guessing.
One honest word before you start
This is a tool with a setup that is a little more hands-on than clicking install. Because it is not yet in the Office store, you add it manually, a process that takes about five minutes and a bit of care. The guide below walks you through every step. If you are the kind of person who enjoys making capable tools work, you will be done before your coffee cools.
Setup Guide
01
Download the manifest file
The manifest is a small file that tells PowerPoint where to find the add-in. Download it and remember where it lands.
Download via Etsy SparkSlides shop02
Put it in a simple shared folder
Create a plain folder with no spaces in the name, for example on your C drive, and move the manifest into it.
C:\PPTAddinRight-click the folder, choose Properties, open the Sharing tab, click Share, pick your own username, then Share and Done. The Sharing tab now shows a network path that begins with two backslashes, such as
\\YOUR-PC\PPTAddin. Copy that path.03
Tell PowerPoint to trust that folder
Open PowerPoint, then go to File > Options > Trust Center > Trust Center Settings > Trusted Add-in Catalogs.
- Paste the network path into the Catalog Url box and click Add catalog.
- Tick the Show in Menu checkbox on that row. This step is easy to miss, and the add-in will not appear without it.
- Click OK to close both windows.
04
Restart, then insert it
Close PowerPoint completely and reopen it. On the Insert tab, open the My Add-ins dropdown and choose the Shared Folder tab. Select SparkSlides Embed and click Add.
05
Embed a page and present
The add-in lands on your slide. Paste a web address that allows embedding, click Embed, then press F5 to present and interact with it live.
Good to know: use a page you own or one that offers an embed option. Some sites block embedding for security, and those will show a blank box. That is set by the site, not by the add-in.
01
Download the manifest file
The manifest is a small file that points PowerPoint to the add-in. Download it to your Mac.
Download via Etsy SparkSlides shop02
Open the PowerPoint add-in folder
In Finder, choose Go > Go to Folder and paste the path below. If the final
weffolder does not exist yet, create it.~/Library/Containers/com.microsoft.Powerpoint/Data/Documents/wef03
Drop the manifest in
Move manifest.xml into that wef folder. That is the whole installation on Mac.
04
Restart, then insert it
Quit PowerPoint fully and reopen it. On the Insert tab, open My Add-ins, find SparkSlides Embed, and add it to your slide.
05
Embed a page and present
Paste a web address that allows embedding, click Embed, then start your slideshow and interact with it live.
Good to know: use a page you own or one that offers an embed option. Some sites block embedding for security, and those will show a blank box. That is set by the site, not by the add-in.
Troubleshooting
The add-in does not appear in the Shared Folder list
Almost always one of three things, in order: PowerPoint was not fully restarted after adding the catalog, the Show in Menu box was not ticked, or the path you pasted was a regular folder path instead of the network share path that begins with two backslashes. Fix whichever applies and restart.
The embedded page is blank or says it cannot be displayed
That page blocks being shown inside other apps, which is a security setting on the website itself and cannot be changed from PowerPoint. Use a page you own, or one that offers an embed option. If it is your own site, you can adjust its embedding setting on your hosting platform.
It works for me, but the embed is blank for someone I sent the deck to
Anyone who opens your presentation also needs the add-in installed to see the live content. Share this guide with them, and once they have set it up, the embed will appear.
Nothing loads at all
The page loads live, so you need an internet connection. Check that you are online and that the address opens normally in a browser.
I changed the manifest and PowerPoint still shows the old version
PowerPoint caches add-ins. Clear the cache by emptying the contents of %LOCALAPPDATA%\Microsoft\Office\16.0\Wef\ on Windows, then restart. Changes to the embedded web page itself do not need this, just refresh.

Can you embed a live website in PowerPoint?
Yes. A PowerPoint content add-in such as SparkSlides Embed displays a live web page directly on a slide, and the page stays interactive while you present, so you can click, type, and use it without leaving PowerPoint. The address you embed is saved in your own presentation file.
Does the embedded website update automatically?
Yes. Because the page loads live each time you open the presentation or start a slideshow, it always shows the most current content. There is nothing to refresh manually — dashboards, charts, and data pages reflect real-time information automatically.
Can you embed a webpage in PowerPoint without the Web Viewer add-in?
Yes. Microsoft retired the Web Viewer add-in, but you can still embed live web pages using a modern content add-in like SparkSlides Embed. It is built on the current Office add-in platform and works on Windows, Mac, and PowerPoint on the web.
Can you embed interactive HTML in PowerPoint?
Yes. Any web page that allows embedding can be loaded onto a slide as a live, interactive HTML frame. The audience can click, scroll, type, and interact with the content during the presentation, just as they would in a browser.
Does it work on Mac?
Yes. SparkSlides Embed works on Mac, Windows, and PowerPoint on the web. On Mac you install it by placing the manifest file in the PowerPoint wef folder, then restarting PowerPoint.
What happens to the embed offline or without internet?
The embedded web page requires an internet connection to load. If you are offline, the embed area will remain blank until connectivity is restored. Your presentation file itself is unaffected — the add-in simply cannot reach the web page without a network.
How much does the add-in cost?
SparkSlides Embed is a one-time purchase on the SparkSlides Etsy shop. There are no subscriptions, usage fees, or hidden costs. You install it once and use it in as many presentations as you like.
Is it safe? Does it access my data?
SparkSlides Embed stores the web address you enter inside your own presentation file and nothing else. It does not collect personal data, does not phone home, and does not access any content on your computer beyond the PowerPoint slide it runs on.
What is the best way to make a PowerPoint presentation interactive?
The most direct way to make a PowerPoint slide truly interactive is to embed a live web page on the slide, so your audience can use a real tool, dashboard, or calculator during the talk. PowerPoint's built-in animations, triggers, and hyperlinks add movement and navigation, but only embedded live web content lets people interact with real, current software inside the slide itself.
Are HTML presentations replacing PowerPoint?
Web-based presentation tools that use HTML, such as reveal.js and Slidev, are a growing trend because they make slides interactive and easy to share online. In practice PowerPoint still dominates, because it offers dependable offline presenting, presenter view and timing controls, fine-grained slide control, and near-universal familiarity at work. For most people the realistic path today is not an immediate switch but a combination: keep PowerPoint for flow and control, and embed live web content on the slides where interactivity matters.
Why will some web pages not embed in PowerPoint?
Some websites block being displayed inside other apps using a security setting known as a frame policy. This is set by the website itself and cannot be changed from PowerPoint. Pages you own, and pages that offer an official embed option, embed reliably; many dashboards, charts, and tools provide such an embed link.
Does an embedded web page stay interactive during a live presentation?
Yes. In slideshow mode the embedded page is live, so clicking and typing work just as they would in a browser. For the smoothest experience, choose content that fits in the slide area without needing to scroll inside the embed.
What replaced the PowerPoint Web Viewer add-in?
Microsoft retired its Web Viewer add-in, which used to embed web pages in slides. SparkSlides Embed is a modern replacement built on the supported Office add-in platform, and it works on Windows, Mac, and PowerPoint on the web.
Can I combine the interactivity of the web with the control of PowerPoint?
Yes. By embedding a live web page onto a slide with a content add-in, you keep everything PowerPoint does well — presentation flow, presenter view, offline reliability, and slide-by-slide control — while adding the live, interactive content that the web does well.
