Legacy ImageMagick Discussions Archive

I've gone through the online documentation, and read many examples, but I'm obviously missing something rather basic.

How does one process a whole folder of image files (jpgs) while keeping the filenames intact, but putting the resulting files in a new folder? (I'm working in a Windows 10 environment, not Linux or Unix)

For example:
convert *.jpg -quality 75 -resize 1920x1920^> -unsharp 10x4+1+0 C:\Resized\
doesn't work as I had hoped.

nor does:
convert *.jpg -quality 75 -resize 1920x1920^> -unsharp 10x4+1+0 C:\Resized
nor does:
convert *.jpg -quality 75 -resize 1920x1920^> -unsharp 10x4+1+0 C:\Resized\*.jpg

So what am I missing?

Uuu-ha You're struggling less with imagemagick than with windows batch scripting !

I'd recommend learning some powershell commands...

another hint is mogrify, which is meant for batch processing (without writing the loops yourself). But in the end I always returned to my own looping, because mogrify is limited (or more complicated) in terms of input patterns and so on.

As olidem mentioned, the mogrify tool is probably better suited for this job. Try a command like this...
That will read all the JPG images in the current directory, resize them, and sharpen them. Then it writes the finished images with their original file names into a directory you specify with "-path ...".

There are some more complicated tasks that can't be done with "mogrify", so running "convert" in a simple "for" loop is the best approach. If your actual command is as simple as your example, "mogrify" should do what you need very well.

Thank you, GeeMack!!! That's exactly what I was looking for/missing!
