I have around 400 images that are taken from a 8 megapixel camera. I want to reduce the image size to around 4k pixels. What is the fastest way to do this, I have access to both windows and linux systems.

Really only 4k pixels? Anyway, using GraphicsMagick you can run:

gm mogrify -output-directory 4k -resize 52x78 *.jpg

Or, if you prefer, ImageMagick has pretty much the same syntax.

Irfanview. Does it all and it's free.

  • Yes, Irfanview would be my choice for this job on Windows machine. The gui interface to specify this batch job makes its slightly easier than using command line.

  • Ya, that's what's great about Irfanview. Has a batch processing mode with a ton of options. In fact, batch processing is really all I use it for.

On Windows I've always used nconvert:

nconvert -thumb 78 78 -o $\thumb\% *.jpg

XnView (on the same page) can do the same.

  • Might be that I got the syntax for -o slightly wrong; just didn't have a directory of images to test with.
