+    As this is a public service, some limitations compared to WebP Cloud are imposed:
+
+    - Fly supports a maximum original image size of 8MB, while WebP Cloud supports up to 80MB.
+    - Fly cache time is 1 day, while WebP Cloud has unlimited time (can be manually cleared at any time).
+    - It does not support parameters like `blur`, `sharpen` for image processing.
