PowerPoint Bullet Lists: How to Change the Bullet Character to a Custom Image

You have a bullet list in a PowerPoint presentation and you want the bullet character to be a small image instead of the default dot, arrow, or checkmark. PowerPoint allows you to use any picture file as a custom bullet, which gives your slides a unique visual style without needing to insert separate icons for each item. This article explains how to replace the standard bullet symbol with a custom image using the Bullets and Numbering dialog, including the supported file formats and size considerations.

How Custom Image Bullets Work in PowerPoint

PowerPoint stores custom bullet images as part of the presentation file, not as linked external files. When you apply a picture bullet, the program embeds a copy of the image into the slide layout or text placeholder. This means the bullet image appears correctly even if you send the file to someone else or move it to another computer.

The image replaces the entire bullet character, not just its background. PowerPoint scales the picture proportionally to fit the line height of the text. If the image is very wide or tall, the program may crop or distort it to fit the square bullet space. For best results, use a square image with a transparent background, such as a 64×64 pixel PNG file.

You can apply a custom bullet to an entire list at once or to individual paragraphs. The feature works in all versions of PowerPoint for Windows, including PowerPoint for Microsoft 365, PowerPoint 2021, PowerPoint 2019, and earlier versions.

Steps to Change the Bullet Character to a Custom Image

Follow these steps to replace the default bullet symbol with a picture file on your computer or from an online source.

1. Select the bulleted list
   Click anywhere inside the bullet list you want to modify. To change all bullets in the list at once, click the text placeholder border so that the entire list is selected. If you want to change only one bullet, click that specific line.
2. Open the Bullets and Numbering dialog
   On the Home tab, in the Paragraph group, click the arrow next to the Bullets button. From the dropdown menu, select Bullets and Numbering at the bottom. The Bullets and Numbering dialog opens.
3. Click the Picture button
   In the dialog, click the Picture button near the bottom-left corner. This opens the Insert Pictures window.
4. Choose your image source
   In the Insert Pictures window, you have three options:
   – From a file: Click Browse and navigate to the image file on your computer. Select the file and click Insert.
   – Bing Image Search: Type a keyword in the search box and press Enter. Select an image from the results, then click Insert.
   – OneDrive or SharePoint: Click the OneDrive or SharePoint link and browse to the image file in your cloud storage.
5. Confirm the bullet change
   After you insert the image, the Bullets and Numbering dialog closes automatically. The selected list now uses your custom image as the bullet character. If the image appears too large or too small, adjust the text font size on the Home tab. The bullet scales with the font.

Using an SVG Icon as a Custom Bullet

PowerPoint supports SVG files as custom bullets. SVG icons scale perfectly at any size without losing quality. To use an SVG file, follow the same steps above but choose an SVG file from your computer or insert one from the built-in PowerPoint icon library. To access the icon library, go to Insert > Icons, select an icon, click Insert, then copy the icon and paste it as a bullet using the Picture option. However, pasting an icon directly as a bullet is not supported; you must save the icon as an SVG file first or use the Insert Pictures dialog to select the SVG file.

Common Issues When Using Custom Image Bullets

The image bullet appears as a black box or shows a white background

This happens when the image format does not support transparency, such as a JPEG file. JPEG images always have a solid white or colored background, which covers the text behind the bullet. Use a PNG or GIF file with a transparent background instead. You can also use an SVG file, which inherently supports transparency.

The bullet image is too large or too small

PowerPoint scales the image to match the font size of the paragraph. If the image is very large, it may appear oversized on small text. To fix this, reduce the font size of the list on the Home tab, or resize the image in an image editor before inserting it. A good starting size is 32×32 pixels for body text at 12pt and 64×64 pixels for headings at 24pt.

The custom bullet does not appear in the Bullets dropdown menu

The picture bullet you insert is applied only to the selected list. It does not become a permanent option in the Bullets dropdown. To reuse the same custom bullet on another list, you must repeat the process. Alternatively, create a slide master with the custom bullet applied to a placeholder, and that bullet will be available for all slides using that master.

The bullet image disappears when I change the theme

Changing the theme or the slide layout can reset the bullet style. To preserve the custom bullet, apply it after the theme is set. If you must change the theme, reapply the custom bullet using the same steps.

Custom Bullet Image vs Default Bullet Symbols

Item	Custom Image Bullet	Default Symbol Bullet
Appearance	Any picture file (PNG, JPG, SVG, etc)	Dot, arrow, checkmark, or other symbol from the Bullets library
File size impact	Adds the image size to the presentation file	No additional file size
Scalability	Scales with font size; may distort if image is non-square	Scales perfectly at any font size
Transparency support	Requires PNG, GIF, or SVG for transparency	Always transparent
Reusability	Must reinsert for each list, or use Slide Master	Available in the Bullets dropdown once added
Theme compatibility	May reset when theme changes	Adjusts color and size with the theme

You can now replace standard bullet characters with any image you choose, including PNG icons with transparent backgrounds, SVG icons, or even small logos. For a consistent look across multiple slides, apply the custom bullet to a text placeholder in the Slide Master by selecting the placeholder, opening the Bullets and Numbering dialog, and inserting the picture there. This saves time when you need the same image bullet on dozens of slides.
