After Saving the Assembly as a Part, Save the Part as a neutral file format such as Parasolid, STEP or IGES. Next, Open this new file and SolidWorks should bring it in as a "dumb solid" and this file should be smaller.

I could reduce the part file size by a few meg, but the part vs. assembly file is still larger. Part file is 8mbyte assembly file is 3.8mbyte.
I could set the image quality down to minimum but the save tessalation box is greyed out and I can't remove the check.
Sorry, that option is only available in Part files. Were you able to reduce your file size?
I hadn't done this in a while, so I tried this again this morning. Here's what I got;
I got a 2.8MB assy to a 1.3MB part with no further growth after multiple saves.
Here's what helped;
1. In both the native assy file and later, the new part file, go to tools, options, document, and slide the image quality indicators all the way to the left. And, uncheck save tessellation when saving.
2. When saving the assy as a part, choose exterior faces.
3. When round tripping, save as Parasolid x_t.
4. Again, in the new part file, set the image quality indicators all the way to the left. And, uncheck save tessellation when saving.

I just tried this with a large assy. I saved an assy (15Mb) as a part, file size is reduced to 6Mb. Save again, 12 Mb, save a third time 14.4Mb. I exported as a "dumb solid" and got 5Mb. I hit save, 12.4Mb, once more 13.4Mb. Not much space saving here.......
