Best way to Compress Image in Asp net core

Question

I want to Compress all uploaded image before it gets Uploaded on the websites disk.
I have allot of small thumbnail sized images (shopping page) on a page so the images need to be at there minimal size while stil be in good quality so it will not take that long to load a page

How I upload the images right now:

                        string name = Guid.NewGuid().ToString() + "_" + image.FileName;  
                        string filepath = Path.Combine(root, name);  
  
                        using var stream = System.IO.File.Create(filepath);  
                        await image.CopyToAsync(stream);

You can do something like the below,

Bitmap resizedImage = new(image, new Size(256, 256));  
using var stream = new MemoryStream();  
resizedImage.Save(stream, ImageFormat.Jpeg);  
byte[] bytes = stream.ToArray();  

// Write bytes to your desired location
