Find and Optimize Large Images

Large image files increase page load time and negatively impact the user experience on your site. More information about image requirements and best practices.

The “Images Larger than 2 MB” policy in Siteimprove can help find large images on your site.

Access the Large Images Report

  1. Log in to Siteimprove at siteimprove.boisestate.edu.
  2. In the Siteimprove menu, navigate to Quality Assurance, then select “Summary” and “QA Policies.”
  3. Select the “Images Larger than 2 MB” policy from the list of Quality Assurance Policies.
  4. The Policy Details page will provide a list of images on your site with a file size larger than 2 MB. Use the dropdown arrow in the Pages column to find the corresponding page.

Optimize Image Files

Where possible, upload optimized images (less than 1 MB) as you are creating content. If Siteimprove identifies large images on your site, removing the large image file and replacing it with an image that has been optimized for the web (using Photoshop or other photo editing software) is the recommended process for maintaining the quality of the image. If you need help resizing Boise State photographs, please contact Boise State Visual Services.

Some common image sizes are included in the following table.

It is possible to scale images in WordPress however, be aware that this process may negatively impact the quality of the image, so be sure to review scaled images on your site to ensure photo quality is maintained. Images should never be scaled up, only reduced in size.
