I need some Graphic Design/product brochures altered

I have some high resolution 2 sided printable product brochures which are a non standard size. \r\n\r\n1. I would like them to be resized to A5, but if that is too small, I can work with A4. I do not want the layouts changed.\r\n \r\n2. they need to be converted to a pdf product brochure to be uploaded on our website (remove the printing guidelines and any filename text etc)\r\n\r\nI have uploading one, but there are 63 in total to be done.\r\n\r\nthanks
