You may be asked to make sure that the files you submit to Canvas are less than 500MB. The instructions below describe how to compress your PDF and PPTX (PowerPoint) files.
Compressing PDF files
You can compress PDF files using Adobe Acrobat DC, which you have access to as part of the Adobe Creative Cloud package. To learn more about accessing the Adobe Creative Cloud package, please visit the student intranet.
To compress your PDF file:
Open your file in Adobe Acrobat DC
Select File>Save as Other>Reduced File Size PDF…
Choose the Adobe Version Compatibility you prefer, bearing in mind that the ‘Retain existing’ option is the most compatible file
Choose where you want to save your compressed file
Rename your compressed file so that you don’t overwrite the master file
Compressing pictures in a PowerPoint presentation
If you are working in PowerPoint, you can reduce the file size of your presentation by compressing pictures within your file. Please note, these instructions only work on the desktop version of PowerPoint. Instructions for downloading the desktop version of PowerPoint can be found on the student intranet.
To compress your pictures in your PowerPoint presentation:
Save your presentation and give it a new file name so that your original file is preserved
Select one of the pictures in your presentation
Select Format>Compress pictures
Choose whether you want to apply compression only to this picture or to all of the pictures in your file
Choose whether you want to delete the cropped areas of pictures
Choose the resolution you require bearing in mind that you may want to present high resolution images
You can use the accessibility checker in Microsoft Powerpoint to make your PowerPoint presentations more accessible.
To use the accessibility checker
Select the Review tab
Select Check accessibility
Work your way through all of the errors and warnings in the accessibility report
It’s likely you will be asked to provide alt text for any images or objects in your presentation. You can leave this blank if the images or objects are decorative, but if the images or objects provide information, you should include this information in the alt text.
Take a look at the tech tip below to see a demonstration of the accessibility checker:
You can embed forms into Canvas assigments to provide students with a due date for when they must complete the form by. You might do this if you want students to provide emergency contact details, for example.
You can use the Canvas Icon Maker to create icons and buttons in Canvas that link to other content, such as a Module or Page. These icons are more accessible than any images of text you may have used in the past, because they are in SVG format. SVG files do not get blurry when we zoom in or use Canvas on a phone.
Start by opening the Rich Content Editor (RCE) and then select the Icon Maker
Enter a name for your icon and provide alt text: the alt text should be the same as the text you’re planning to use in your icon
