You need to externally compress the image and then save as normal. there are many online compression tools.

You can use LEADTOOLS Imaging Pro SDK technology in your application. https://www.leadtools.com/sdk/products/imaging-pro You can leverage the RasterCodecs class, which allows you to load any LEADTOOLS supported raster image format and export to any LEADTOOLS supported raster image format. You can utilize the RasterImageFormat enumeration and QualityFactor property, to indicate the image compression type and to specify the tradeoff between quality and compression. https://www.leadtools.com/help/sdk/v21/dh/to/compression-quality-factors.html I am unaware of the file format you are using, so the code below uses JPEG: // Load in source image using (RasterCodecs _codecs = new RasterCodecs()) using (RasterImage _image = _codecs.Load(@ "FILE PATH TO INPUT IMAGE" )) { // QualityFactor takes values between 2 to 255 // 2 being highest quality, 255 being most compression _codecs.Options.Jpeg.Save.QualityFactor = 100; _codecs.Save(_image, @ "FILE PATH TO OUTPUT IMAGE" , RasterImageFormat.Jpeg, 0); }
