A new tool was added to ArcGIS 10.3 to convert a page in a PDF to TIFF. This is especially useful for the asset management work I do, as I often get pdf drawings or maps which need to be georeferenced. I created a function to wrap around the ArcGIS one to enable the conversion of more than one page in the pdf at a time.
By default, the function will only convert the first page. Specifying a start and/or end page will override the defaults. Link to the code is here.
