The new Leopard Preview has some great features, including editing and rearranging pages in a PDF file. However, what you might not know is that you can take some number of images and create a single PDF out of those images.
To create a single PDF from multiple TIFF, JPG, or other supported file types, do this:
- Open any PDF -- single or multi page, it doesn't matter -- in Preview. You'll remove it later, so any image will do.
- Show the sidebar (either Shift-Command-D, or via the menu or toolbar button).
- Drag the single page images you want to use to the sidebar. They will be formated one per page.
- Select the PDF you opened in step one -- use Shift-Click to select multiple pages, then choose Edit » Delete. Don't worry, this image is not actually erased from your hard drive, just 'deleted' from the sidebar.
- Selected File » Save As » PDF, and you're done.
