Every time we have a show, there are issues with the files an artist has sent us. This time one of the artists sent the master image sequence as .tif instead of .png. With 7350 individual images to convert, I need an automated solution. With a quick Google search, I found Batch Image Converter 1.0 for Mac as a free download. Simply change the destination format to png, select all of the files I need to convert and drag and drop onto to conversion window. I even duplicated the application and opened a second instance to convert more than one set of files at the same time.
