use the Image class provided by the System.Drawing namespace

using System.Drawing;
using System.Drawing.Imaging;

// Load the JPG image from file
Image jpgImage = Image.FromFile("path/to/image.jpg");

// Create a new bitmap with the same dimensions as the JPG image
Bitmap pngBitmap = new Bitmap(jpgImage.Width, jpgImage.Height, PixelFormat.Format32bppArgb);

// Draw the JPG image onto the new bitmap, which will convert it to PNG format
using (Graphics graphics = Graphics.FromImage(pngBitmap))
{
    graphics.DrawImage(jpgImage, new Rectangle(0, 0, jpgImage.Width, jpgImage.Height));
}

// Save the PNG image to file
pngBitmap.Save("path/to/image.png", ImageFormat.Png);

// Dispose of the temporary objects
jpgImage.Dispose();
pngBitmap.Dispose();

In this code, we first load the JPG image from file using the Image.FromFile method. We then create a new Bitmap object with the same dimensions as the JPG image, and draw the JPG image onto it using the Graphics.DrawImage method. This converts the JPG image to PNG format. Finally, we save the PNG image to file using the Bitmap.Save method with the ImageFormat.Png parameter.

Note that we dispose of the temporary objects at the end of the code using the Dispose method, which releases the resources used by them.
