Hello there,

I'm having a hard time here, I'm trying to convert all .jpeg I have in a folder thanks to the command
convert –resize 1600x1200 *.jpg
but I have always have this error showing up :

Microsoft Windows [version 6.1.7601]

C:\Users\Cyril>cd C:\Users\Cyril\Desktop\Photos\Resize

C:\Users\Cyril\Desktop\Photos\Resize>convert -resize 1600x1200 *.jpg

My computer is running with Windows 7 x32

Thanks for your help

convert –resize 1600x1200 *.jpg

Convert does not work this way. It needs one input specified and one output. You would have to loop over each image and process it.

But mogrify works the way you want. It process all files in a folder and makes an output for each.
But you will walk over each input with the output, unless you use the -path option.

Well, I'm very new to this...it worked 2 times then begun to bug.
Is there any software or command that I can use to do multiple resize ? Like it work with a Droplet: with photoshop but with a free software ?

Yes, IM can do that, but you need to write a script. In your case, for droplet, it would be a Windows Bat file and I do not use Windows. So one of the other Windows users would need to help you. Here is the basic command of the form you need for each image. See

since in Windows, parentheses are not escaped by \ and new lines are symboled by ^ rather than \

I will see what I can do ! Thank you for help
