How to use JpegTran to recursively process all images by overwriting them in a directory using Windows?

Question

Now I have the following batch file that I use to process my images:

@echo none cd %1 md "%~1\ProcessedJPEGS" for %%i in (*.jpg) do "C:\Program Files\Image Optimization\jpegtran.exe" -optimize -progressive -copy none "%%i" "%~1\ProcessedJPEGS\%%i" move /Y "%~1\ProcessedJPEGS\*.*" "%~1" rd "%~1\ProcessedJPEGS" pause 

As you can see, this is not perfect, but my skills are ridiculous at best, so I need help here :)

What I want to do is run this batch in a directory and recursively process all the images and overwrite them.

Thanks in advance, Arky

Based on your command line, this should process all JPG files from the current folder and below. Check it out on a sample set of files / folders to make sure it works for you.

 @echo none for /f "delims=" %%a in ('dir "*.jpg" /b /s /a-d') do ( echo processing "%%a" "C:\Program Files\Image Optimization\jpegtran.exe" -optimize -progressive -copy none "%%a" "%%a.tmp" move /Y "%%a.tmp" "%%a" >nul ) pause
