I found your page on Google (Jasc Image Robot – October 2009) and was just wondering if you still have Image Robot or if you know where I can get a copy of it?
No, and no.
But a quick look at Google shows that XnConvert might do what they want. It will read 500+ image formats, and output to 100+ formats.
And it’s freeware.
I also briefly looked at Advanced Batch Image Convertor, but the two problems I had with it were that a) it won’t read PaintShop Pro images (PSP) and b) only 5 export formats.
