Hi,

You can use this library

https://imageprocessor.org/

Here is the documentation,
https://imageprocessor.org/imageprocessor/imagefactory/#methods

Example:
byte[] photoBytes = File.ReadAllBytes(file);
// Format is automatically detected though can be changed.
ISupportedImageFormat format = new JpegFormat { Quality = 70 };
Size size = new Size(150, 0)
using (MemoryStream inStream = new MemoryStream(photoBytes))
{
    using (MemoryStream outStream = new MemoryStream())
    {
        // Initialize the ImageFactory using the overload to preserve EXIF metadata.
        using (ImageFactory imageFactory = new ImageFactory(preserveExifData:true))
        {
            // Load, resize, set the format and quality and save an image.
            imageFactory.Load(inStream)
                        .Resize(size)
                        .Format(format)
                        .Save(outStream);
        }
        // Do something with the stream.
    }
}
