how to compress scanned pdfs - TR4720

[LMHudson]

I have used Canon IJ Scan Utility Lite.app to set PDF Compression to High. It seems to have no effect. A one-page US Letter scanned document weighs 2MB on Standard and the same on High. If I compress it using Adobe Acrobat, it weighs 113 KB without any loss of quality. How can I scan to the compressed size without having to use Adobe Acrobat?

Using MacOS 14.2.1 Sonoma

What are you scanning? Text-only documents? Images? Forms (mixture of text and graphical elements)?

Thank you. I am running on macOS Sonoma 14.2.1. My Pixma TR4720 is new. It replaced a TR8520 yesterday. I notice that its install introduced a new Canon IJ Scan Utility Lite.app but left untouched the Canon IJ Scan Utility.app which bears a Date Modified in 2018, when the TR8520 was first installed. I am scanning a text document on 300 dpi in black & white.
