PDF files by their very nature are already “compressed.” I think you are asking about reducing the file size, typically done by downsampling raster images and using lossier compression. (Raster images are typically the source of most of the file size for very large PDF files!) Such functionality simply does not currently exist in the Acrobat Reader for iOS which even with certain subscription functions is nowhere near the functionality of Adobe Acrobat Pro (Windows or MacOS) or Adobe Acrobat Standard (Windows only).
