The Image Audit automatically finds images that are problematic and groups them together so that you can quickly check and fix them.
Images too big
These images are larger than necessary, which increases the size of your presentation. We recommend compressing these images to reduce file size.
Low compression images
These images are saved using very high quality, or in an inefficient format e.g. a photograph saved as a PNG. We recommend compressing these images to reduce file size.
Cropped images
These images have been cropped but the cropped areas are still in the file, just hidden. To avoid any content being distributed with your presentation, you can quickly pass through and check any cropped portions of images to ensure they don’t contain anything sensitive or incorrect.
You can also remove all the cropped areas of images, either individually or all at once using the compress pictures feature. Compress and choose 'Delete cropped areas of pictures' to reduce file size.
Auto-generated images
These images were created automatically by PowerPoint for backward compatibility. They cannot be directly edited, however if they are too big, you do have options:
SVGs
PowerPoint automatically creates PNG versions of any SVGs to show in PowerPoint 2013 or earlier. Read our guide on how to compress these images.
WDPs
When you add effects to images, PowerPoint creates a WDP file (the original) and a PNG version (with effects); changes to the effects trigger PowerPoint to recreate the PNG from the WDP. Read our guide on how to compress WDP images.
Images that are too small
These images are too small. Some images may appear blurry, grainy or otherwise visually poor. We recommend checking each image to check the quality and replace if needed.
You can also try the new built-in Upscale feature in Picture Format menu.
Distorted images
These images have been scaled more in one dimension than the other, creating distorted images. We recommend that you check each image visually to ensure it’s not problematic, simply right-click and choose "Show in PowerPoint" from the menu to jump to the image.
You will see in the Inspector how distorted the image is, as it lists the scale factors for width (W) and height (H).
If the image is a problem and it needs to be adjusted, Slidewise now has a "Fix Distorted Image" feature. Fixing distorted images can be a little frustrating; standard reset options also remove effects/sizing, and manual scaling using the format shape pane is fiddly. Our new solution simplifies this: right-click a distorted shape (see example) in the Inspector and select "Fix Distorted Image."
The ‘fix’ automatically corrects the aspect ratio by matching the shorter dimension's scaling to the longer one, instantly fixing distortion while keeping the shape's approximate size. Watch the fix in action below.
Flipped/Rotated images
When images are flipped or rotated in PowerPoint, it’s not always possible to tell visually. When you flip an image in PowerPoint, it flips the image shape, not just the image. If you later replace this image, the replacement image will also be flipped.
This can be confusing for users, and it is a bigger problem when working with PowerPoint templates with placeholders that are intended to be replaced every time the template is used.
Slidewise alerts you to any images that are flipped or rotated, and gives you a list that you can check through and fix as needed.
Broken/corrupted images
This category will highlight any images that are corrupted and might need to be replaced. Check any images to see if it is visibly corrupted and replace as needed.
