I have a scanned file that I have saved as a pdf. I need to resize to upload but needs to be 1.0m and under. I don't want to lose resolution.
Hello and welcome to the forum!
Not sure what you mean by '1.0m' - I'm assuming that '1 MB' is the likely answer - correct? You might want to tells us about your computer (model/year), OS X installed, and also the current size of the PDF file.
But to address your question, there are a number of options: 1) Free online services - just google 'free online PDF compression'; 2) Using Adobe software; and 3) Using 'Preview' which is an app and part of OS X - see the image below (arrow) where I've opened a PDF in Preview, then under 'File' chose 'Export' -> 'Quartz Filter' -> 'Reduce File Size'.
Now, keep in mind that 'how much' a PDF file can be compressed will depend on many factors - take a look at these links which more thoroughly discusses the choices given above -

ADDENDUM: In Finder, a right-click on a PDF file will bring up the context menu which includes a compression option into a ZIP file - and most forums allow these to be uploaded, so just another consideration.
