@ASKE
I have gone through all of your steps, is it normal to be waiting a long period of time for the items to be converted during the last step? I have been waiting a good 15 minutes.

Odds are, the actual file is about the same size. They’re reporting a different measure of space used: Even a one byte file occupies an entire block on the hard drive. Windows is reporting how big the data in the file is, while Mac OS is reporting how much of the hard drive space (one block) the file is using. Also, Mac OS will include the space required for the thumbnail Finder displays along with the image; Windows will hide that space in a different, hidden file.

HI:
I have a whole bunch of images (an album of about 1,000 images) that I need to convert from png to jpg. Is there an easy way to do a large batch like that on a Mac?

I know I can open each png image and convert it to a jpg. Do I have to do them all one by one?

Any advice would be appreciated.

Lorne

You have to hold alt (option) key when you click on the file type to expose hidden types like gif, icns, etc.

You can use the ‘sips’ command-line tool, which I personally find easier than firing up Automator. Check out http://straylink.wordpress.com/2009/01/24/os-x-command-line-image-manipulation/ for examples.

To convert a bunch of TIFs to JPGs, I just did something like:

for x (*.tif)
sips -s format jpeg $x –out outdir/$(basename $x .tif).jpg

Gari, do you have an option for .gif in yours? My older versions of Mac had that extension, but Lion doesn’t seem to. If not, is there a way to add extension options?
