How to Resize Images for Canvas LMS
Upload your image to imgresizr.com. For a Canvas course card image (the thumbnail shown on the dashboard), use the Crop tool to set approximately a 2.66:1 ratio, then resize to 1012×380px. This fills the course card area cleanly without cropping awkwardly. For course content images embedded in pages, resize to 800–1000px wide — this ensures images display correctly in Canvas's fluid content layout without causing horizontal scroll. For profile pictures, resize to 300×300px in a 1:1 square ratio. Always compress to under 500KB for fast page loading within course modules.
Canvas LMS Image Tips
- Course card images should have minimal text — they display very small on the dashboard
- Use high-contrast, colourful images for course cards — they help students distinguish courses visually
- Embed images at specific widths in Canvas pages rather than letting them scale dynamically
- PDF-converted images should be at least 150dpi for readable text within Canvas
