externalization for generating plots in my document. For heavy plots the output PDF for a figure can grow to few hundred KB. I used Adobe Acrobat to optimize the PDFs which resulted in a significantly reduced size (from 300 KB to 20 KB). My
tikzpictures purely contain plots but no text.
First, what kind of information is stored in the original file which makes it huge compared to the optimized version?
Second, to optimize the files, one way is to use Ghost script for post-processing the PDF files, however, is there anyway we can get
tikz to generate smaller files in the first place? Or can we make LaTeX optimizes the PDFs generated by
tikz externalization without the need for separate post-processing?
