Try to reduce PDF size by re-saving it or by flattening pages to images.

One PDF. If the result is not smaller, the original is returned.
Re-saving often changes little, because most PDF size comes from embedded images and fonts that are left untouched.
Flattening renders each page as a JPEG. This can shrink scans and photo-heavy files, but text stops being selectable or searchable, and links and form fields are lost.
A smaller file is not guaranteed. Pixuna does not target a specific size.
