Is there any way to convert image formats from Ubuntu terminal?
Particularly from eps to png/jpg or to any other formats.

You can use the
imagemagick command line tool
You can use it like this:
convert myfile.eps foo.png
For anyone who lands here trying to figure out how to work around ImageMagic's
convert: not authorized without reverting the change that was made to the system-wide security policy to close a vulnerability, here's how to rasterize EPS files by calling Ghostscript directly:
gs -dSAFER -dBATCH -dNOPAUSE -dEPSCrop -r600 -sDEVICE=pngalpha -sOutputFile=foo.png myfile.eps
-dSAFERputs Ghostscript in a sandboxed mode where Postscript code can only interact with the files you specified on the command line. (Yes, the parts of EPS, PS, and PDF files that define the page contents are in a turing-complete programming language.)
-DBATCHcauses it to quit when it reaches the end of the input file, rather than switching to an interactive PostScript prompt.
-dNOPAUSEprevents it from prompting to continue after each page
-dEPSCropasks for the rendered output to be cropped to the bounding box of the drawing rather than padded out to the declared page size (See the manual for details.)
-r600specifies the DPI you want to render at
-sDEVICEspecifies the output format (See the Devices section of the manual for other choices.)
UPDATE: I've since learned that
-o foo.png is a cleaner, easier-to-remember shorthand for
-dBATCH -dNOPAUSE -sOutputFile=foo.png so the better command would be this:
gs -dSAFER -dEPSCrop -r600 -sDEVICE=pngalpha -o foo.png myfile.eps
The manual also mentions that, some day, they eventually hope to be able to make
-dSAFER the default though, given backwards compatibility needs, who knows if that will ever happen.
