We ported the following functionalities into the asset editor of the Contentful Web App:

• rotate image
• mirror image
• resize image (both maintaining aspect ratio and scaling to desired size)
• cropping images (no aspect ratio, original aspect ratio, custom aspect ratio)
• cropping images to a circle (converts to PNG)
• cropping SVG (converts to PNG)

In the past we provided this functionality through a third party which announced to discontinue that service.
