I scan my material at the highest resolution possible. Each scan is about 3 mg in jpg. format. When you convert to PDF the entire file is compressed anyway. With PDF you can increase the size so scan and keep as original.

A really good video here that describes what you want with resolutions of 300 by 300

scratch that ,first page came out at 17megs and that was at 300dpi,so a little trial and error is called for i think.

Can you not use OCR to get the text then scan in any pictures seperately?

Or convert to greyscale and only use colour for images.

I normally use 100-150dpi

Ideal for quick, good quality scanning.

The file size is usually around 1mb per jpg
