How to Create a Liquid Glass Effect in PowerPoint

The “liquid glass” effect is everywhere right now — frosted panels, soft blur, subtle highlights that look like light is hitting curved glass. PowerPoint doesn’t have a “blur background” button but we can fake it.

This effect works because PowerPoint allows you to fill a shape with the slide background. Once you understand that trick, everything clicks.

Let’s build it from scratch.

Step 1: Create a Blurred Background

First, you need two copies of your image.

1. Insert your image onto the slide.
2. Duplicate it (Ctrl/Cmd + D).

One will stay sharp, one will become blurry.

Blur one copy

1. Select one image.
2. Go to Picture Format → Artistic Effects → Blur.
3. Open the Format Picture pane.
4. Increase the blur amount significantly (don’t be shy).

You want it very blurry.

Step 2: Turn the Blurred Image into the Slide Background

1. Cut the blurred image (Ctrl/Cmd + X).
2. Right-click the slide background.
3. Choose Format Background.
4. Select Picture or Texture Fill.
5. Under Picture Source, choose Clipboard.

Now your slide background is the blurred image. Your sharp image should still be sitting on top.

Step 3: Add the “Glass” Shape

1. Insert a shape (rectangle works great).
2. Remove the outline.
3. Right-click → Format Shape.
4. Under Fill, choose Slide Background Fill.

The shape now displays whatever is behind it. As you move it around, it automatically updates to match the background beneath it. That’s the core of the liquid glass illusion.

Step 4: Add the Light Reflection (The Important Part)

Right now, it looks like a blurry rectangle. To make it look like glass, we need a subtle light edge. You can toy around with using 3D bevel effects, but I prefer using a gradient line.

Add a Gradient Outline

1. Right-click the shape → Format Shape.
2. Go to Line.
3. Choose Gradient Line.
4. Remove extra gradient stops until only two remain.

Set the lighting direction

Think about where the light is coming from in your image.

If light is coming from the top left:

• The top-left edge should be brighter.
• The bottom-right edge should be darker/more transparent.

Adjust the angle of the gradient until the white highlight sits where the light source would naturally hit.

Refine the effect

• Make one gradient stop solid white.
• Make the other stop white but highly transparent.
• Reduce the line width (around 1–2 pt usually works well).

Now it starts to feel like glass instead of just a shape.

Step 5: Add Multiple Panels (Optional)

If you add multiple “glass” panels:

• Adjust each gradient line direction individually.
• Make sure the highlight aligns with the imaginary light source.

Otherwise, it won’t feel realistic.

Recap

To create a liquid glass effect:

1. Duplicate your image.
2. Blur one copy heavily.
3. Set the blurred image as the slide background.
4. Add a shape with Slide Background Fill.
5. Add a gradient outline to simulate light.

PowerPoint doesn’t have a blur-behind tool–but it does have enough tools to fake it beautifully.
