Rotate an image to change its orientation or angle - CDN

Alibaba Cloud CDN supports automatic image rotation and manual image rotation. You can rotate images to change the orientation or angle.

Note

The image editing feature of Alibaba Cloud CDN, the image editing feature of DCDN, and the Image Processing (IMG) feature of Object Storage Service (OSS) are three different features.
Image editing is a paid service and is free of charge until further notice.

Automatic rotation

Images that are taken by some cameras carry the orientation property. Automatic rotation applies only to images that contain the orientation property. After you enable the automatic rotation feature, Alibaba Cloud CDN automatically rotates images. For more information, see Enable and use image editing.

Important After you enable automatic conversion to WebP, the cache hit ratio decreases. It automatically increases after a short period of time. Do not enable this feature during peak hours.
