How to Compress Image Size in C#

This quick tutorial shares information on how to compress image size in C#. You’ll learn to manage the compression of various image types, such as JPEG, PNG, and BMP, while maintaining quality.

Benefits of Compressing Image Sizes

  1. Reduced File Size:
    • Saves storage space.
  2. Faster Uploads and Downloads:
    • Improves performance when sharing images online.
  3. Optimal Performance:
    • Enhances application responsiveness by minimizing image load times.

Prerequisites: Preparing the Environment

  1. Set up Visual Studio or any compatible .NET IDE.
  2. Install the Aspose.Imaging library via NuGet Package Manager.

Step-by-Step Guide to Compress Image Size in C#

Step 1: Configure the Project

Start by configuring your project to use Aspose.Imaging for image compression.

Install-Package Aspose.Imaging

Step 2: Load the JPEG Image

Load the source JPEG file into an Image class object.

using (var originalJpegImage = Image.Load("SampleJpeg.jpg"))
{
    // Processing will follow here
}

Step 3: Initialize Compression Options

Create an instance of the JpegOptions class to configure compression settings.

var jpegOptionsToCompress = new JpegOptions();

Step 4: Set Color Type for Compression

Configure the color type to Grayscale to help reduce the size.

jpegOptionsToCompress.ColorType = JpegCompressionColorMode.Grayscale;

Step 5: Set Compression Type

Set the compression type to Progressive to improve loading speed visually.

jpegOptionsToCompress.CompressionType = JpegCompressionMode.Progressive;

Step 6: Save the Compressed Image

After configuring, save the compressed image to the disk.

originalJpegImage.Save("result.jpg", jpegOptionsToCompress);

Complete Code Example for Compressing Image Size

Here’s the complete code that demonstrates how to compress an image:

// Load the original image to be compressed
using (var originalJpegImage = Image.Load("SampleJpeg.jpg"))
{
    // Create JpegOptions class object to customize output image
    var jpegOptionsToCompress = new JpegOptions()
    {
        ColorType = JpegCompressionColorMode.Grayscale,
        CompressionType = JpegCompressionMode.Progressive,
    };

    // Save the output compressed image on the disk
    originalJpegImage.Save("result.jpg", jpegOptionsToCompress);
}

Conclusion

This tutorial has guided you through compressing image sizes in C# using Aspose.Imaging. With the ability to configure various properties during compression, you can effectively manage image sizes without compromising quality. For additional functionality, consider learning about resizing images or other image manipulation techniques in C# using Aspose.
