The percent symbol will need to be escaped on Window's command prompt. This is because the of "Parameter Extensions" functionality defined by the % character. To escape it, use double percent %%. Also, I believe you want to use -quality, as -quanlity is not defined in Command-Line Options.

exec('convert -strip -quality 75%% 0.jpg 00.jpg');
