What a slideshow is and why Canvas has one

A slideshow in Canvas is a way to display images or documents one at a time, in order, on your screen. Instead of scrolling through a long page or opening ten separate files, you click through them like pages in a book. Canvas — the learning management system used by many schools and universities — includes a slideshow tool built into its file viewer.

You might use this to present lecture notes with images, show a series of diagrams, or display student work one piece at a time. The slideshow runs in full screen or a large window, which makes it easier to see details and keeps the focus on one image rather than a whole page at once.

Key Takeaways

  • Canvas shows slideshows automatically when you upload a folder of images or a multi-page PDF to your course.
  • You navigate through slides by clicking arrows, using keyboard keys, or clicking on a slide thumbnail in the sidebar.
  • The slideshow viewer appears when you click on an image or document in Canvas — you do not need to create or upload anything special.
  • You can present slideshows full screen during class or share the link with students so they can view at their own pace.

How to start a slideshow from an image or PDF you have already uploaded

If you have already uploaded images or a PDF file to Canvas, you can view them as a slideshow without any extra steps. Navigate to the folder or assignment where your file is stored, then click on the image or PDF itself. Canvas will open the file in its viewer, and you will see navigation arrows on either side of the image — a left arrow to go backward and a right arrow to go forward.

If your file is a multi-page PDF, Canvas treats each page as a slide. If you have uploaded a folder containing multiple image files, Canvas will show them in the order they appear in the folder. Click the right arrow to move to the next slide, or click the left arrow to return to the previous one.

Using keyboard shortcuts to move through slides faster

Once you are in the slideshow viewer, you can use your keyboard instead of clicking the arrows. Press the right arrow key on your keyboard to advance to the next slide, or press the left arrow key to go back. You can also press the spacebar to move forward one slide at a time.

If you want to exit the slideshow and return to the Canvas page, press the Escape key. These shortcuts work the same way whether you are viewing on a computer or a tablet with a keyboard attached.

Viewing thumbnails and jumping to a specific slide

When you open a slideshow in Canvas, a sidebar appears on the left side showing thumbnail images of all the slides in your presentation. This is useful if you have many slides and want to jump to a specific one without clicking through each one. Click on any thumbnail to go directly to that slide.

You can also scroll up and down in the thumbnail panel to see slides that are not currently visible. If the thumbnail panel is taking up too much space, you can close it by clicking the small arrow or X button at the top of the panel, giving you more room to view the main slide.

Presenting a slideshow full screen during class

To present your slideshow to a group, click the full-screen button in the bottom right corner of the viewer. This expands the slideshow to fill your entire screen and hides the Canvas menu and other distractions. You can still use the arrow keys or on-screen arrows to navigate, and pressing Escape will exit full-screen mode and return you to the normal Canvas view.

If you are sharing your screen during a video call or in-person class, full-screen mode makes it easier for students to see the content. You remain in control of the pacing — students cannot advance the slides themselves unless you share the link and let them view independently.

Sharing a slideshow link with students

You can share the slideshow with students by copying the link to the file and pasting it into an assignment, announcement, or email. When students click the link, they will see the same slideshow viewer you see, complete with navigation arrows and thumbnails. They can move through the slides at their own pace without you controlling the presentation.

If the file is inside a folder in Canvas, make sure the folder itself is shared with students or that the individual file permissions allow them to view it. You can check this by looking at the file's sharing settings — usually found in a menu next to the file name.

Organizing images into a folder so they display in order

Canvas displays images in the order they appear in a folder, so naming and organizing matters. If you have ten images you want to show in a specific sequence, name them with numbers at the start: 01-title.jpg, 02-diagram.jpg, 03-chart.jpg, and so on. This ensures Canvas shows them in the order you intend, not alphabetically by the full file name.

Upload all the images to the same folder in Canvas, then click on the first image to start the slideshow. Canvas will recognize that the other images are in the same folder and include them in the slideshow sequence. If you later add or remove images from the folder, the slideshow updates automatically the next time someone views it.

Frequently Asked Questions

Can I add music or transitions to a Canvas slideshow?

Canvas's built-in slideshow viewer does not support music, animations, or transitions. If you need those features, create your slideshow in PowerPoint, Google Slides, or a similar tool, then upload the file to Canvas. Students can read and view it with full effects, or you can embed it directly in a Canvas page.

What file types work with the Canvas slideshow viewer?

Canvas shows slideshows for image files (JPG, PNG, GIF) and PDF documents. If you upload other file types like Word documents or videos, Canvas will not display them as slideshows — students will need to read them to view. Stick to images and PDFs for the slideshow feature to work.

Can students edit or read slides from the Canvas viewer?

Students can view and navigate slides, but they cannot edit them directly in Canvas. They can read the original file if you have given them permission to do so. read permissions are set in the file's sharing settings, separate from view permissions.

Why are my images not showing up in the right order?

Canvas orders images alphabetically by file name, not by the order you uploaded them. Rename your files with numbers at the start (01, 02, 03) to control the sequence. If you have already uploaded them, you may need to rename them in your computer's file system, delete them from Canvas, and re-upload them in the correct order.

Can I present a slideshow without students seeing the thumbnails?

Use full-screen mode to hide the sidebar and thumbnails. Click the full-screen button in the bottom right corner of the viewer. In full-screen mode, only the current slide and navigation arrows are visible, giving a cleaner presentation view.
