 ## Syntax
 
 ```js-nolint
+copyBufferToBuffer(source, destination)
+copyBufferToBuffer(source, destination, size)
 copyBufferToBuffer(source, sourceOffset, destination, destinationOffset, size)
 ```
 
 ### Parameters
 
 - `source`
   - : The {{domxref("GPUBuffer")}} to copy from.
-- `sourceOffset`
+- `sourceOffset` {{optional_inline}}
   - : The offset, in bytes, into the `source` to begin copying from.
 - `destination`
   - : The {{domxref("GPUBuffer")}} to copy to.
-- `destinationOffset`
+- `destinationOffset` {{optional_inline}}
   - : The offset, in bytes, into the `destination` to begin copying to.
-- `size`
+- `size` {{optional_inline}}
   - : The number of bytes to copy.
 
+> [!NOTE]
+> The `sourceOffset` and `destinationOffset` can be omitted if you are copying part of the source buffer at a `0` offset in both the source and destination buffers. The `sourceOffset`, `destinationOffset`, and `size` can be omitted if you are copying the entire source buffer to the destination buffer.

 ### Return value
 
 None ({{jsxref("Undefined")}}).
