Batch convert BMP to JPEG/PNG

[RampantAndroid]

Hi all,

Looking to batch convert a few hundred images from BMP to JPEG or PNG - what's the best way to do this? Is there a app out there that I can just right a shell script for?

Thanks!

If you do want to script, you can use imagemagick

Imagemagick is very powerful, it has more options than most of us will ever need.

Assuming it is installed in the typical manner here is a very simple script to convert all BMP files in the current directory to PNGs:

for %%f in (*.bmp) do (convert %%~nf.bmp %%~nf.png)

Save this as something like "BMP2PNG.CMD" in the folder containing the files you want to convert and run it.

You can add the /R switch to the for command to process files in sudirectories, and any options needed to the convert command.

I second using Imagemagick from shell scripts, it's an integral part of my RAW processing.
