Recently I found myself needing to quickly and easily convert some .eps files to .pdf. You can simply double click on the EPS in OS X and Preview will convert it however this cannot be done in batch and you have to go through the process of saving the .pdf.

There is a quicker and free solution to this in OS X and it is already built in…. Terminal.app.

1. Open terminal.app
2. Navigate to the directory where the .eps files are located… use ‘cd’ followed by a folder or directory string to move to the folder ‘cd ..’ to move up a directory level and ‘ls’ to tell you what is in the directory your currently in.
3. When you have located the files type the following: epstopdf filename.eps 
4. epstopdf will now convert that eps file to a pdf and place it in the same directory as: filename.pdf
