In Email to PDF toolbar, click ‘Output Settings’. Under PDF optimization section, you can choose between two levels – Optimize for Quality and Optimize for Publishing. The former will give you the best quality of the generated PDF, but the downside is it would have larger file size. On the other hand, the later option will generate the PDF output in compressed format, thereby leading to smaller size of the PDF file. This option is ideal for hosting the PDF files on the web, or for emailing, because of the smaller size advantage.
