It depends on the compression settings you use. PDF permits lossless compression, lossy compression, or no compression at all.

Hi Tacit,

I use PS v. 7.0. When I tried to convert a graphic file into pdf, I do not see any option for compression.
What I see is "Encoding – Zip or Jpeg".
Could you please more specific? TIA

The compression format of the JPG is set with what ever software you used initally when creating the JPG, not during the process of conversion to PDF.

That’s what that means.

Encoding: JPEG means use JPEG compression. JPEG compression is lossy.

Encoding: ZIP means use ZIP compression. ZIP compression is lossless.

Huh?

When you save a PDF, you are given the option of what kind of compression to use (including JPEG compression) and how much to compress. Remember, JPEG is a *comprssion scheme*, not a *file format.* (What people call a "JPEG file" is, technically, a JFIF file compressed using the JPEG compression system.)

so if I am sending a print job use ZIP? and if I want it to share online use JPG?
I am just learning about all the features in Acrobat, there are so many variables

It depends. How is the job being printed? How is the PDF being sent? If the job is being printed on a press, and it’s being sent in such a way that file size is unimportant, then lossless compression is best. However, you’re best off talking to your print shop *before* you start making PDFs (or indeed any other kinds of files!). They can tell you what they need; for example, if you’re working for print, you should probably be working in CMYK, not RGB, and so on.
