Is it possible to batch convert a folder of JPEG images using jpegtran on Windows?
I normally use the following command for one file, but I'm not sure how to apply it to an entire directory of JPEG files:
jpegtran -copy none -optimize a.jpg b.jpg
Thank you.
Run optimize.bat (Run as administrator) to optimize all images in C:/Program Files/Image Optimization (change path in line 3 if you want to optimize another folder).
@echo off
echo Optimizing Images...
cd "C:\Program Files\Image Optimization"
forfiles /s /m *.jpg /c "cmd /c @\"C:\Program Files\Image Optimization\jpegtran.exe\" -copy none -optimize -outfile @file @file"
echo. & echo Process done!

The procedure to optimize all images in a folder is described in the following link. I think it might help you.
