Since my (and my friend's) handwritten class notes are stored in binders, I scanned them with my university copier that as ADF. the output PDF, for example, is 28MB for 68pages (I suppose it's jpeg compressed since I can choose to scan to pdf or jpg). Is there a way to shrink the size considered that:
- I have a mix of plain, squared and striped background, (depending on the availability of the paper! )
- Most of the notes are in single color, but sometimes I used some colors
Is there any other tool that can help optimizing the space?
