+### Splitting PDF files
+`$ convert -density 600 (input.pdf) -crop 50x100% +repage (out.pdf)`  
+
+```
+-density: adjusts the quality of the resulting pdf. Higher values look better, but take longer to process
+-crop 50x100%: this splits the pdf into "left" and "right". 100x50% would split into "top" and "bottom"
