PDF to Book file size limit

Blurb can accept PDF to Book files as big as 2GB, but no bigger.

2GB should be enough space to handle even 440 page books that are rich with images. If your PDF is larger than 2GB, it probably has far more image information in each digital image than is necessary. Be sure that your images are placed at a resolution no higher than 300 ppi. Or try compressing your .jpg images at the high setting instead of the maximum setting. This should eliminate the extra digital information and create a PDF that you can upload to Blurb.
