Lightweight command-line image resizer?

Question

I'm looking for an image resizer / thumbnailer that is lightweight and efficient. Something that does a good job with all image types, but most importantly jpeg and png.

I've looked into ImageMagick and GraphicsMagick, but they are too heavy. This is something I want to distribute with my app, so the smaller the better. I don't need all the functionality of *Magick, just simple resizing.

I've found the FreeImage library which people seem to like as a light library. Does anyone know if there's a simple command-line utility that wraps FreeImage?

Thanks!

Although ImageMagick is pretty big (36.2MB), you only need the convert.exe or mogrify.exe binary, depending on whether you want to create a new image (convert), or overwrite the existing one (mogrify).

Download the no-installer version of ImageMagick (currently ImageMagick-6.8.6-8-Q16-x86-windows.zip), then extract the binary you need.

I took mogrify.exe - a total of 5.66MB; not bad!

Have a look at the netpbm toolkit, the toolkit is just a bunch of small single purpose command line programs that you wire together using pipes. You might be able to find what you need in there.
