Pdf download

hi does anyone know how to upload a pdf onto a site that when people search the companys name they will be able to download their catalog as a pdf?

In acrobat, you can save it as a reduced size pdf. Then just upload it to your site same way you would upload any image, and if they go to that url, they can see it and right click to download. If you want it to download automatically, you need a php download or something like that.
