Hi Brent,


Thanks for your inquiry. We have further investigated the issue and would like to update you that the file is successfully saved and after save it is linearized according to Adobe Acrobat. File size change should not be expected because this methods is only to make file linearized for web optimization. For optimizing PDF file size please check following link for the purpose.


Please feel free to contact us for any further assistance.
