Developers can load, save, and convert Portable Network Graphics (PNG) images in .NET (C# & VB), C/C++, WinRT, iOS, macOS, Java, and web applications. All LEADTOOLS SDK products include full PNG format support. Though natively supported on many platforms, LEADTOOLS achieves superior compression ratios and is able to more accurately decode corrupted PNG files.
