Reduce Image File Size to a specific size ?

Post by niha »

Hi guys,

I did some searchs and found out that ImageMagicK is capable of reducing image file size.

But, if I have a 1,5MB jpg file and I want to reduce the file size to EXACTLY 500KB ( for upload an avatar and highest quality ), is there a way to do so ?

You can use -quality or -compress, but as far as I know, neither will let you specify a desired file size. You have to do that by trial and error until you get the size you want. I don't believe that IM has such a feature.
