How to Make Shapes Transparent in Google Slides: Easy Guide

To make a shape transparent in Google Slides, select the shape, click Fill color (the paint bucket) in the toolbar, click the plus icon under Custom, and drag the transparency slider. Then click OK.

To remove the fill completely, click Fill color > Transparent. The border is a separate setting under Border color.

This guide covers shape fills, borders, gradients, and photo overlays. For images and text, read how to change opacity in Google Slides.

How to Make a Shape Transparent: Quick Steps

These steps are for Google Slides in a browser on a computer.

1. Open your presentation and click the shape to select it.

2. In the toolbar, click Fill color (the paint bucket icon).

3. Under Custom, click Add a custom color (the plus icon). A color window opens.

   

4. Choose the color you want in the color area.

5. Drag the transparency slider. It is the lower of the two sliders. The checkered end is the see-through end.

6. For an exact level, type a number in the A box. 100 is solid and 0 is invisible.

   

7. Click OK.

The shape changes when you click OK. Google Slides saves the color under Custom, so you can use it again on other shapes in the file.

The names Fill color, Border color, and Add a custom color follow Google's Docs Editors Help, which we checked in October 2026. Google's page describes the Hex and RGB boxes of the color window. It does not describe the transparency slider, so those steps follow the screenshots above.

Overview

Use this table to find the right control for each part of a shape.

All of these controls are in the color menus of the toolbar. A color from the standard palette is always solid.

An image is not a shape. For a picture, a logo, or a GIF, use Format > Format options > Adjustments > Opacity. The opacity guide has those steps.

Transparency in Google Slides: What is and Why it Matters

A transparent shape lets the slide behind it show through. This is how you put readable text on a photo or mark one area of a chart.

What is Transparency?

Transparency is how much of the slide shows through an object. Opacity is the same setting counted from the opposite end: 70% transparency is 30% opacity.

For a shape, the setting is part of the fill color. The A (alpha) box in the color window holds it as a number from 0 to 100.

Why Use Transparency in Slides?

• Keep text readable on a photo. A dark see-through rectangle between the photo and the text raises the contrast.
• Point at one area. A light see-through box marks a part of a chart or screenshot and keeps the content visible.
• Show overlap. Two see-through circles make a Venn diagram where the shared area is visible.

Common Uses of Transparency in Presentations

These A values are our suggested starting points. They are not rules or measured data.

Change the value until the text is easy to read in Slideshow mode. Steps of 5 to 10 are enough.

If you need the whole deck and not one overlay, GenPPT designs full slides from a prompt or a file. You get a .pptx file that opens in Google Slides.

Preparing Your Slide for Transparency

Transparency is only visible when something is behind the shape. Set up the layers before you open the color menu.

Selecting the Right Slide

Choose a slide that has a photo, a chart, or another shape behind the place where the shape goes.

On an empty white slide, a see-through fill looks like a lighter solid color. You cannot judge the level there.

Choosing the Shape to Make Transparent

1. Click Insert > Shape > Shapes and choose a shape. A rectangle is the usual choice for an overlay.
2. Drag on the slide to draw it.
3. Move and size the shape so that it covers the area you want.

The fill setting works on closed shapes: rectangles, circles, block arrows, and callouts. A text box takes the same fill setting, and its text stays solid.

A line has no fill. Change its color with the pencil icon in the toolbar, the same tool that sets a border.

Setting Up Your Workspace

• Order the layers. Select the shape and click Arrange > Order to move it in front of or behind other objects.
• Open a group. If the shape is in a group, double-click the shape to select it alone, or click Arrange > Ungroup.
• Check your access. You need edit access to the file. With view or comment access, the color tools are not available.
• Widen the window. In a narrow browser window, the toolbar hides Fill color and Border color behind the More (three dots) button.

Making a Shape Transparent in Google Slides

The quick steps are enough for most slides. This section gives the details for each step, the fully transparent fill, and the border.

Accessing the Format Options

Do not look in Format options. For a shape, the transparency control is in the toolbar.

• Shapes: use the Fill color and Border color icons in the toolbar.
• Images: use Format > Format options > Adjustments > Opacity.

If you open Format options with a shape selected, you see size, position, drop shadow, and reflection settings. You do not see Adjustments, because that section is for images.

Adjusting the Transparency Slider

The color window has two sliders. The upper slider sets the hue. The lower slider sets the transparency.

• Drag toward the checkered end to make the fill more see-through. In our screenshot, that is the left end.
• Type in the A box for an exact level. Use the same number on each slide for a consistent look.
• Read the Hex box. With transparency, the code has eight characters. The last two hold the alpha value.

To use the same fill on other shapes, hold Shift and click each shape. Then click Fill color and click the saved color under Custom.

Make the Fill Fully Transparent

1. Select the shape.
2. Click Fill color.
3. Click Transparent at the bottom of the menu.

The fill disappears. The border and any text in the shape stay visible, so the shape becomes an outline.

If the shape has no border, it is now invisible. Give it a border with Border color.

Make the Border Transparent

The fill setting does not change the border. To fade the outline:

1. Select the shape.
2. Click Border color (the pencil icon next to Fill color).
3. Under Custom, click Add a custom color.
4. Drag the transparency slider or type a value in the A box.
5. Click OK.

To remove the outline, click Border color > Transparent. Overlays and highlight boxes usually look cleaner with no outline.

Previewing the Changes

• Deselect the shape. Click an empty area of the slide. The selection handles hide the edges of the shape.
• Check in Slideshow mode. Click Slideshow at the top right and look at the slide in full screen. Press Esc to exit.
• Undo a bad result. Press Ctrl + Z on Windows or ChromeOS, or Cmd + Z on Mac.

A faint fill can look different on a projector or a shared screen. Check the slide on the screen you will present on.

How to Make Shapes Transparent in Google Slides

Shape Transparency in the Google Slides Mobile App

The mobile apps do less than the browser version.

Google's help pages for the Android app and the iPhone and iPad app tell you how to add, move, resize, rotate, order, and group objects. They list no transparency control for a shape fill.

A 2023 guide from InsideTheWeb reports that the Fill color menu in the app can remove the fill and cannot set a custom level. The option is Transparent on Android and No color on iPhone. We did not test this, and app versions differ.

For a partial transparency:

1. Open the file in a browser on a computer.
2. Set the level with Fill color > Custom > Add a custom color.
3. Open the file in the app again. The level is stored in the file, so the shape keeps it.

Images are different. Google documents an Adjustments control for image transparency in the Android app. The opacity guide has those steps.

Advanced Transparency Techniques

Layering Transparent Shapes

See-through shapes that overlap mix their colors. A Venn diagram is the common example.

1. Insert two circles and give them different fill colors.
2. Set the A value of each fill to 50.
3. Drag the circles so that they overlap. The shared area shows a mix of the two colors.
4. Click Arrange > Order to choose the circle on top.
5. Select the two circles and click Arrange > Group so that they move together.

Each layer makes the area behind it harder to see. Keep to two or three layers.

Fade a Shape with a Transparent Gradient

A gradient lets one edge of a shape be solid and the opposite edge be see-through. Use it for a dark band behind a title at the bottom of a photo.

1. Select the shape and click Fill color.
2. Open the Gradient tab and click Custom at the bottom.
3. Click a gradient stop, click its color circle, and choose Custom.
4. Set the color and the transparency in the color window.
5. Do the same for the other gradient stop, then click OK.

For a clean fade, use the same color on the two stops and change only the transparency.

Google's help pages do not document the gradient window. These steps follow the SlidesCarnival gradient guide, so the labels in your version can differ.

Combining Transparency with Other Effects

The fill is not the only part of a shape with a transparency setting. Third-party guides report that the shadow and the reflection have their own.

• Drop shadow. Click Format > Format options > Drop shadow. The reported settings are color, transparency, angle, distance, and blur radius.
• Reflection. The Reflection section in the same sidebar has a reported transparency setting.

These settings are separate from the fill transparency. The blur radius changes the shadow, not the shape.

The drop shadow names follow the SlideModel drop shadow guide, which shows them on images and text boxes. Google's help pages do not list these settings and we did not test them on a shape, so the labels in your version can differ.

Using Transparency for Highlighting

To mark one area of a chart or screenshot:

1. Draw a rectangle over the area.
2. Set the fill to yellow or a brand color with an A value of 20 to 30.
3. Click Border color > Transparent. For a sharper frame, keep a solid border in the same color.

To dim everything except one item, place four black rectangles around the item, one on each side. Set each fill to an A value of 60 to 70 and remove the borders.

If the highlight covers a text box, right-click the shape and choose Order > Send backward. The text then keeps its full contrast.

Troubleshooting Common Issues

Shape Not Becoming Transparent

• The palette has no slider. The slider is in the custom color window. Under Custom, click Add a custom color.
• You opened Format options. Its Adjustments section is for images. For a shape, use Fill color.
• The object is an image. A picture cropped to a circle or a star is still an image. Use Format options > Adjustments > Opacity.
• The shape is in a group. Double-click the shape to select it alone, or click Arrange > Ungroup.
• You cannot select the shape. It can be part of the theme layout. Click Slide > Edit theme and change it there.
• The tools are missing or gray. You have view or comment access. Ask the owner for edit access.
• You are in the mobile app. Open the file in a browser on a computer.

Transparency Not Displaying Correctly

• The shape still looks solid. Nothing is behind it, or the object behind it has the same color. Move the shape over a photo to check.
• The shape hides the text. The shape is above the text. Right-click the shape and choose Order > Send backward.
• The color looks different. A see-through fill mixes with the colors behind it. Choose a darker fill or raise the A value.
• The outline is still solid. The border has its own setting. See Make the Border Transparent.
• The shape disappeared. The fill is Transparent and the shape has no border. Press Ctrl + Z or add a border color.
• An exported file looks different. We did not test how PowerPoint and PDF exports show see-through shapes. Open the exported file and check those slides before you send it.

Reverting Changes

1. Press Ctrl + Z on Windows or ChromeOS, or Cmd + Z on Mac, to undo the last change.
2. To make the fill solid again, click Fill color and choose a color from the standard palette. Those colors are always solid.
3. To keep the color and remove only the transparency, add the custom color again and type 100 in the A box.
4. To go back further, click the Last edit (version history) icon at the top right and restore an earlier version.

Reset image does not help here. That command is for images only.

Before a large change, select the shape and press Ctrl + D (Cmd + D on Mac) to duplicate it. The copy is your backup.

Practical Applications of Transparency

Creating Watermarks

The method depends on what the watermark is.

• A logo file is an image. Fade it with Format options > Adjustments > Opacity.
• A word such as DRAFT or CONFIDENTIAL can be Word art. Word art takes the same fill control as a shape.

For a text watermark:

1. Click Insert > Word art, type the word, and press Enter.
2. Select the Word art and click Fill color > Custom > Add a custom color.
3. Type a low value in the A box and click OK. We suggest 10 to 20 as a starting point.
4. Click Border color > Transparent.
5. Drag the Word art to the center or a corner of the slide.
6. Right-click the Word art and choose Order > Send to back.

To show the watermark on each slide, add it to the layout in Slide > Edit theme.

Designing Overlays

A dark overlay makes white text readable on a photo.

1. Click Insert > Image and size the photo to cover the slide.
2. Click Insert > Shape > Shapes and choose the rectangle. Draw it over the full photo.
3. Click Fill color > Custom > Add a custom color. Choose black, type 50 in the A box, and click OK.
4. Click Border color > Transparent.
5. Right-click the rectangle and choose Order > Send backward until it is above the photo and below the text.
6. Set the text color to white.
7. Click Slideshow and read the text from a distance.

If the text is still hard to read, raise the A value by 10. The W3C contrast guideline gives a fixed target: a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text.

For a title at the bottom of the photo, use a band with a transparent gradient and keep the top of the photo clear.

Enhancing Visual Appeal

• Use one overlay color in the deck. Click the saved color under Custom on each slide.
• Use one level for one job. For example, set all photo overlays to 50 and all highlight boxes to 25.
• Remove the outline on overlays and highlight boxes.
• Keep to two or three layers. More layers make the slide dark and hard to read.

For more layout rules, see these presentation design tips.

Conclusion

Remember one path: Fill color > Custom > Add a custom color, then the transparency slider or the A box. Use Border color for the outline and Fill color > Transparent to remove the fill.

Then check the slide in Slideshow mode. A fill that looks correct in the editor can look different on a projector.

If you do not want to build each overlay by hand, GenPPT is an AI presentation generator. You start from a prompt, a PDF, a Word document, or a link. It drafts an outline for you to approve, designs each slide, and exports .pptx and PDF files.

The .pptx file opens in Google Slides. If you are new to that step, see how to convert PowerPoint to Google Slides.

The slides are image-native designs that you edit in chat. Check the numbers and claims yourself.

The trial costs $1 for 3 days of full access and needs a card. After the trial, the price is $25 per month or $99 per year. See the pricing page.

Frequently Asked Questions

How do I make a shape 50% transparent in Google Slides?

Select the shape and click Fill color. Under Custom, click Add a custom color, type 50 in the A box, and click OK. The fill is then half see-through.

How can I make an image transparent in Google Slides?

Select the image and click Format > Format options. Open Adjustments and drag the Opacity slider. An image does not use the Fill color control. The opacity guide has the full steps.

Where can I find the transparency tool in Google Slides?

Google Slides has no single transparency tool. For a shape, the control is in Fill color > Custom > Add a custom color. For an image, it is the Opacity slider in Format options > Adjustments.

What types of rectangle shapes can I add in Google Slides?

Click Insert > Shape > Shapes. The menu has a plain rectangle, a rounded rectangle, and rectangles with cut or rounded corners. All of them take a see-through fill in the same way.

Can I make my text transparent in Google Slides?

Regular text has no transparency setting. Use Insert > Word art and set its fill with Fill color > Custom, or choose a lighter text color. A text box fill can be see-through, and the text in it stays solid.

How do I make a shape completely transparent?

Select the shape, click Fill color, and click Transparent at the bottom of the menu. The border and the text stay visible. To hide the border too, click Border color > Transparent.

Is it possible to adjust the transparency of different elements on a slide?

Yes. Each shape has its own fill and border colors, and each image has its own Opacity slider. To give several shapes the same level, select them and click the saved color under Custom.
