I've noticed when I save an image as a JPG (using "Save For Web") I can get a good compression to quality ratio, however when I simply use "Save As" and choose JPG, the file size is much larger. I've played around with the quality sliders but I can't seem to obtain that good quality / hi-compression that the "Save For Web" feature Provides.
As an example I saved an image out using "Save for Web" with Medium quality Jpg settings. This file came out at 60k (the image size is 1536 x 1024). I saved the same file out using "Save As" (jpg) with the quality set to 3. Of course this made the image look blocky and its file size was 124k.
The only reason I am asking is because I need a way to Batch numerous images that don't get 'blocky' and have a small file size. Any suggestions would be greatly appreciated.
