Add a caption to an image in PowerPoint
If you want to tell your audience what a photo shows on a slide, you can add a caption as visible text below or beside the image. A short caption is often enough for a single photo. The steps in this guide do not assume that menus are identical across PowerPoint versions: verify the options in your own app and check that the caption appears in the right place on the slide.
Do not confuse a visible caption with alt text. Alt text is a separate accessibility description intended to describe an image to people using screen readers. Microsoft also associates alt text in PowerPoint with accessibility, so do not assume that visible text takes its place (Microsoft’s FAQ about alt text).
Choose a method and placement
First, open the presentation, go to the relevant slide, and find the image that needs a caption. Check whether there is enough room to put text below or beside it. If there is an empty area on the image, you could place the text there too; however, choose another location if the text would cover an important part of the image. These are design choices: decide based on your slide’s layout and whether your audience can read the text comfortably.
If you are creating a new slide, Microsoft’s guide to slide layouts notes that PowerPoint includes a layout called “Picture with Caption.” The guide describes choosing a layout via Home > Slide Layout; if you do not see the same names in your version, check your own menu to see whether the relevant layout is available (Apply a slide layout). When adding a caption to an existing slide, you can also use an empty text area or the control for adding text; verify the control’s name and location in your app.
Write and place the caption
- Select the slide where you want to add a caption. If the image’s size and position are already suitable, leave them unchanged; first assess the space available.
- Open the PowerPoint control you use to add visible text to a slide. If the name of the text option looks different in your version or interface, verify it in your app’s menu or by searching its help.
- Place the text near the relevant image. If putting it below makes the connection clear, use that position; if there is not enough room below, choose the empty space beside it. If there is more than one image on the same slide, keep each caption close enough to make clear which image it belongs to.
- Keep the caption concise and accurate. Describe the photo or add context the audience needs to understand it. Do not guess at an unknown location, date, or source.
- Review the slide in presentation view. If the text seems cut off, hard to distinguish from the background, or matched with the wrong photo, adjust its position or wording.
Rather than assuming there is one size for everyone to use for font size, contrast, and spacing, test readability on your own slide. The editing view on screen may not be enough; if the slide will be shown as a presentation, check it in that view too.
A specific example: a field photo
Fictional example: A team uses a single photo in a presentation about work on a coastal walking path. The slide is titled “Fieldwork.” They place the photo on the left and a short caption just below it: “Fictional example: Observation on the coastal walking path in spring 2026.” On the right are two brief pieces of context needed for what the presentation needs to accomplish: “Observation area: walking path” and “Photo: taken during a field visit.”
The date and location in this example are explicitly identified as fictional. In a real presentation, use this information only after verifying it. Leave it out if it is unknown. If the caption becomes several hard-to-read lines below the image, shorten the main point; consider presenting any necessary additional information elsewhere on the slide.
Check while editing
After moving the image or caption, check the position of both again; it should still be clear which image the visible caption belongs to. This guide does not assume that a version- and selection-dependent command such as grouping is a required step. If you are considering using an option that moves objects together, verify that it is available in your own PowerPoint menu and try it on the result first. You can also move the image and text separately and manually check their positions again without using such an option.
If the text is not visible, first check that you are on the right slide and in the right view. If the text blends into the background, change its color or position. If the caption could be confused with another image, move it closer to the relevant image or clarify the wording to indicate what the image shows.
Frequently asked questions
Should I put the caption below or beside the image?
Choose whichever position on your slide connects the text to the image more clearly and keeps it readable. If there is not enough room below, placing it beside the image may work. If there is more than one image, make it clear which one each caption matches.
Is a caption the same as alt text?
No. The caption in this guide is text that appears on the slide. Alt text is for accessibility, and you should not assume that visible text automatically takes its place. Check the alt text settings you plan to use separately in your own version of PowerPoint.
Should the image and caption move together?
That depends on how you edit your slide. If you plan to use a command to move them together, verify that it is available in your own menu. If you are unsure, move the two items separately and check the layout again after each change.
Final checklist
- The caption describes the right image; details such as date, location, and source have been verified.
- The text is close to the relevant image, and it is clear which image it belongs to.
- The text is readable in the slide’s presentation view and does not cover an important part of the image.
- The positions of the text and image have been checked again after either one was moved.
- The visible caption has not been confused with alt text used for accessibility.
