Through an error I think was (inadvertently) caused in your last post, I found an error in my OP and fixed it, logged in the Update 1; the symptom is the "//" in $ for f in [SOURCE_DIRECTORY]/*; do convert "$f" -channel A -threshold 50% -channel RGB -negate -threshold 0 -negate -channel ...

Is there a way to combine your command with the one that was mentioned in the OP (the command on the Super User URL answered by DavidPostill) ? If not I'll have to do it in 2 commands (and I'd rather have it done in 1).

I think it's this forum that is breaking the link if you take what's following discourse-server/ in it, it should work. For the images information $ identify *.png 28c795e4db4c71da104642b271964c3a_(bard).png PNG 1031x1031 1031x1031+0+0 8-bit sRGB 25236B 0.016u 0:00.000 ...

So from some grey-scale images, which are basically monochrome with antialiasing, I used GIMP fuzzy select tool with a 0 threshold then made a mask out of that to make sure I'd end up with a monochrome image, for design purpose, not to save on the file size.

Aaah! Back to about 5 seconds per conversion. :D I knew something I did was wrong as I've heard so much good things about ImageMagick. Thanks again for your help. Just in case this was skipped (I'm not hoping for a reply but it would be nice): Optionally, could you let me know of other differences ...

Well I used your version of the command and got the following error: >"C:\Program Files\ImageMagick-6.6.9-Q16\mogrify" --format png -normalize *.bmp Magick: unable to open image `--format': No such file or directory @ error/blob.c/OpenBlob/2587. Magick: no decode delegate for this image format ...

So should I use the following?

mogrify *.bmp -normalize --format png

Thanks again or letting me know of Mogrify and a difference from Convert. Before entering the command, just changing convert for , I checked mogrify options and all those I previously used (OP 1st paragraph) seemed supported but after running it I got the error >"C:\Program Files\ImageMagick-6.6.9 ...

The 1st time I used ImageMagick (not testing it), it took about 10 hours on this dual 2 GHz with 2Gb (of RAM) to convert about 1000 BMP of about 4Mb (each) into PNG with the command convert *.bmp -normalize -set filename:fname %t +adjoin %[filename:fname].png The 2nd time I was amazed as it took ...
