Optimize
Reduce file size using a quality profile suited to screen, balanced, or print output.
Make a PDF small enough to email or to fit an upload limit. Choose a profile: screen gives the smallest file for reading on a display, balanced keeps images clear at a sensible size, and print keeps enough resolution for paper. Scanned and image-heavy documents shrink the most; a PDF that is mostly text may already be close to its minimum size.
It depends on what is inside. Scans and photos often shrink by more than half; text-only files may barely change because there is little to compress.
Yes. Compression re-encodes images and streams inside the file; it does not turn pages into pictures.
Balanced. If the portal still rejects the size, try screen, which is the smallest.
