How to Convert JPG to PNG Using C#
Converting file formats may seem like a routine task encountered by graphic designers. Yet, underestimating its significance would be a mistake. The evaluation of your work might depend on how swiftly and effectively you tackle this task. Typically, original images need conversion into formats better suited for printing or online publication. If the original image originates from a graphic editor, it might be in vector format. In this scenario, it must be rasterized and converted to a raster format for publishing purposes. You have the choice to save the image in an uncompressed format for optimal quality or convert it to a lossless compressed format to reduce file size. In certain contexts, like web publishing, you can opt for lossy compressed formats. Specially designed algorithms for image data compression permit a significant reduction in file size while preserving acceptable image quality. This facilitates fast image file downloads from the internet. In order to convert JPG to PNG, we’ll use Aspose.Imaging for .NET API which is a feature-rich, powerful and easy to use image manipulation and conversion API for C# platform. Open NuGet package manager, search for Aspose.Imaging and install. You may also use the following command from the Package Manager Console.

JPG What is JPG File Format
A JPEG is a type of image format that is saved using the method of lossy compression. The output image, as result of compression, is a trade-off between storage size and image quality. Users can adjust the compression level to achieve the desired quality level while at the same time reduce the storage size. Image quality is negligibly affected if 10:1 compression is applied to the image. The higher the compression value, the higher the degradation in image quality.

PNG, Portable Network Graphics, refers to a type of raster image file format that use loseless compression. This file format was created as a replacement of Graphics Interchange Format (GIF) and has no copyright limitations. However, PNG file format does not support animations. PNG file format supports loseless image compression that makes it popular among its users. With the passage of time, PNG has evolved as one of the mostly used image file format. Almost all Operating Systems have support for opening PNG files. For example, Microsoft Windows viewer has the capability to open PNG files as the OS has by default the support available as part of installation.
