Hello, I want to convert a bunch of photos from jpg to eps. What is the best (ideally free) app to do it? I have PS CS6 but I don't think it can do batch conversion. Changing the file extension from jpg to eps does not work. Thanks.

It sure can! You just need to record an Action (Window>Actions) in Photoshop to save a file as an EPS with the required settings. Then select File>Automate>Batch to apply that action to your files. Or if you feel show-offy, you can create a droplet instead.

Hope that helps!

Thanks. I am trying it. Under EPS option, there is a list under "Encoding". Should I use ASCII85, ASCII, binary, or any of those JPEG options?

I guess it depends on the intended purpose of the files. If you're sending them to a third party, give them a call and get the specs. If its for your own purposes then select whatever settings work for you - trial and error time! ;-)

Changing the file extension never changes a file's format.
Also, changing a JPEG to an EPS file may not do what you're expecting; it will not, for instance, make the contents of the file editable in Illustrator.

I am trying to include some photos taken by my iPhone in a Latex document. It is for academic publishing.

It would be useful to know why you want to convert JPG files to EPS format in order to best answer your question. Do you have an end use that can handle only EPS-format files?
Sometimes I can change the format of a document by changing the extension. Mac OS does the rest automatically. In this case, it failed.

This is all true, of course.

An JPEG is invariably just a grid of pixels. An EPS can be pixels and/or vectors. If you convert a JPEG into an EPS then vectors aren't going to magically appear - but that's only an issue for you if you expected them to! ;-)

If you're looking to vectorise JPEG images then that's a whole different ball game (and a rather nasty, messy one at that).

Yes. EPS files are useful because they can contain postscript; vector art. Simply saving a JPEG as EPS does not magically give one lines and points in the file. You will need to do a live trace or recreate the art for this. JPEGs are flattened, and do not contain any layered art.

Does the journal you are writing for have how-to information for what you're trying to do? A lot of journals do this to help people with the always-painful issue of providing graphics and images for publication. The people who publish the journal know what works for their process and what doesn't.

And there is the ability to add PostScript overlays and such. Good point.

No, this is not something that works natively within the operating system. Can you provide an example where you believe it does?

Usually they require pictures in eps format.

What I'm thinking is that the journal may have information for authors about the best way to convert from format A (JPG in your case) to EPS, "best" meaning ways that work best on the journal's end of things. That could help answer your earlier question about ASCII, binary, etc.
