Is there any way to batch convert .jpg files into single .pdf files?
Never forget your little fellow Automator, sitting in a hard drive near you :)
Launch Automator, create a new workflow. Now you need to add two actions:
Your workflow should look like this:
Now read the options for each Action and customize accordingly. Investigate similar actions (especially in the Files & Folders category) and perhaps the Photos if you want to transform your images from JPG to something else. In fact, go ahead and look all over automator, there are a lot of interesting things there. :)
When you're satisfied with your Workflow, click "Run" on the top right corner. Watch the magic happens and depending upon the number of items and your CPU power, you might go grab a coffee/tea.
I don't know if this works with .jpg files but the easiest way I know to convert text is to select print in the file menu, then in the lower left of the print menu select save as PDF.
I'm more at ease with commandline tools such as ImageMagick, which you can install through Homebrew:
After that you can simply do this in a Terminal:
and if the resulting PDF is a bit too big you can try:
Of course ImageMagick also works on other Unix systems, and even on cygwin.
