Use of the mobile internet is growing faster on a daily basis. More and more users access the internet from their mobile devices – think of smartphones, netbooks, iPhones and in the near future: iPads. In the mobile world, bandwidth is still an issue (unlike in the world of desktop-internet). It’s even more important therefore to keep down the filesize of PDFs that you want users to download from your website. It’s not too complicated to reduce file sizes without any quality loss e.g in images. You just have to do it.
