Scans and embedded images usually drive the size
Most “huge PDF” problems are not caused by text. They come from scanned pages, large images, repeated graphics, or a document that was effectively turned into many high-resolution pictures inside one file.
Do not split the file blindly
Splitting can work, but it is often a workaround rather than the real fix. First figure out whether you need page extraction, better image handling, or a different file-sharing workflow.
What to try first
Inspect the document, remove pages you do not need, and decide whether the destination truly requires one large PDF. Many sharing problems disappear once the file contains only the necessary pages.
