Why I use Image to convert image from jpg -> png it will cropped in c#

February 4, 2024

In c#, I use Image to convert image from jpg -> png it will cropped. Even I set resolution, still the same

Here is the code:

Image image = Image.FromFile(imagePath);
image.Save("Image.png", ImageFormat.Png);
image.Dispose();

The result (I use android studio icon as example):

>Solution :

Use the Bitmap namespace

    static void ConvertJpgToPng(string imagePath)
    {
        using (Image image = Image.FromFile(imagePath))
        {
            // Create a new Bitmap with the same dimensions as the original image
            Bitmap bitmap = new Bitmap(image.Width, image.Height);

            // Create a Graphics object from the Bitmap
            using (Graphics g = Graphics.FromImage(bitmap))
            {
                // Draw the original image onto the new Bitmap
                g.DrawImage(image, 0, 0, image.Width, image.Height);
            }

            // Save the new Bitmap as PNG
            bitmap.Save("Image.png", ImageFormat.Png);
        }
    }
