IronPDF Package Size

I am trying to use IronPDF, but I am being held up due to the size of the DLL.

For environments that are restricted by initial package size (example: AWS Lambda), please use IronPdf.Slim.

This package contains the IronPdf.dll, but you will then need to set Installation.AutomaticallyDownloadNativeBinaries = true to have the IronPdf.Native.Chrome package for your platform downloaded at runtime.


If targeting a specific target runtime, you can delete the /runtimes folder not in use (either x86 or x64)


Iron Software will split editing functions and Html-rendering in to two separate packages.

This will benefit customers who do not require Html-to-Pdf rendering

Feature Requests:

Please contact if you would like to see separate x86 and x64 package versions.
