Hello,

You could refer to this Xamarin official Image resizer example: ImageResizer.

After my tests, this code works fine in MAUI Android and iOS. For Windows, you need to replace WINDOWS_UWP with WINDOWS.

Then, you could call this method in your code in the following ways:

imageData = memoryStream.ToArray();
var resizedImgData = await ImageResizer.ResizeImage(imageData, 300, 300); 

Best Regards,
