Reduce the IronPDF Runtimes Folder Size

IronPDF ships native rendering binaries for every supported platform, so the runtimes folder in a default publish can be large. Targeting a single runtime identifier (RID) at publish time trims it down to just the platform you deploy to.

Publish for one RID and turn off a self-contained build:

dotnet publish -r win-x64 --self-contained false

dotnet publish -r win-x64 --self-contained false

The -r win-x64 switch keeps only the Windows 64-bit natives instead of every platform's, and --self-contained false leaves the .NET runtime out of the output so it isn't bundled alongside a framework-dependent deployment. Swap win-x64 for the RID that matches your target, such as linux-x64 or osx-arm64.

To make sure the folder is included in your deployment in the first place, see Managing the Runtimes Folder.
