What version of IronPDF should I use?

I see there are a few different versions of IronPDF. How do I know which one is the best for me?

To avoid missing dependencies issues it is not recommended to use IronPdf.Slim. However, IronPdf.Slim is highly useful when the targeted OS is unknown. To allow Windows, Linux, or MacOS dependencies to be downloaded at run-time  IronPdf.Installation.AutomaticallyDownloadNativeBinaries must be set to true.

Please note that for IronPdf.Slim apart from being portable, it will not save the user any space at run-time. IronPdf relies on two dependencies IronPdf.Slim(contains IronPdf.dll) and IronPdf.Native.Chrome(contains Chrome (default) renderer) based on platform. For example, in windows environment at run-time IronPdf.Native.Chrome.Windows will be downloaded, in Linux IronPdf.Native.Chrome.Linux will be downloaded, and for MacOS depending on which processor is being used either IronPdf.Native.Chrome.MacOS or IronPdf.Native.Chrome.MacOS.ARM will be downloaded.
