+Controls amount of invisible metadata (EXIF data) that should be preserved.

+Color profiles and EXIF rotation are applied to the image even if the metadata is discarded. Content Credentials (C2PA metadata) may be preserved if the [setting is enabled](/images/transform-images/preserve-content-credentials).
+
+Available options are `copyright`, `keep`, and `none`. The default for all JPEG images is `copyright`. WebP and PNG output formats will always discard EXIF metadata.
 
 :::note
-Even when choosing to keep EXIF metadata, Cloudflare will modify JFIF data (potentially invalidating it) to avoid the known incompatibility between the two standards. For more details, refer to [JFIF Compatibility](https://en.wikipedia.org/wiki/JPEG_File_Interchange_Format#Compatibility).
