When I used Preview's "Export" feature to export a 1.4MB jpg file to a one page pdf file, the resulting pdf is as large as 14MB, which is really surprising and annoying. I tried to reduce the file size, for instance by "reduce file size" quartz filter, but the pdf became so reduced (56KB) that the result was not readable at all.
Is there anyway to remedy this? A built-in solution is greatly appreciated.
