Reduce File Size Tool is removing my vector transparency. How can I control this?

Question

I am exporting my PDF from GIS Pro - which has a raster aerial and then vector polygons on top which have a transparent fill. I can view the pdf in Revu and everything looks as it should (Raster aerial and transparent vector polygons). However, when I go to reduce file size in Revu, my vector polygons get a solid fill (transparency removed). Is there a way to control this through Bluebeam Revu settings so my raster aerial gets reduced but my vector graphics do not get modified?

Attached is an example file. Thanks for any insight in advance!

Thanks, Dhanush.  I am using Bluebeam Revu x64 Complete Version 21.10.

I honestly am having troubles finding the Optimize PDF tool. Can yo provide a bit more insight as to how I can find that tool?

Hi EADoll

I've seen similar behaviour before. Reduce File Size can sometimes flatten transparency, especially with PDFs that contain both raster images and vector objects. If you haven't already, try Optimise PDF instead, as it gives you a bit more control over what gets compressed. I'd also be interested to know which version of Revu you're using, as that could make a difference. Hopefully someone else has tested this workflow too!

Thank you
