Single command to create multiple file formats from single source file with ImageMagick

Question

I'd like to render a single file say 1.jpg to multiple Read/Write formats ImageMagick supports for eg. 1.png, 1.tif, 1.pdf etc. on a Windows machine. Is there a quick command to do that or do I have to run convert each time to render 1.jpg to each new output format I want?

Like this:

convert 1.jpg \
        \( +clone -write 1.gif +delete \) \
        \( +clone -write 1.png +delete \) \
        1.tif

Thanks it works! Minor irritation is it creates two copies of gif and png files, any ideas on fixing that?

Oh, that's weird. Mine does not do that - I use version 6.8.9. Maybe try and upgrade if you are running an older version.

Mine is 6.8.9-0 and am running it on Win 7 x64.

@MarkSetchell: If you use +write instead of -write then you can save yourself the +delete...

@KurtPfeifle Cool - why do you have \( and \) around your writes by the way? You could equally do convert ... +write a.gif +write a.tif +write a.png a.pnm

To make it create only one copy of GIF, PNG and other written files, use this command (asumuing, you want to convert myinputfile.jpg):

name=myinputfile

convert                     \
    ${name}.jpg             \
   -resize 50%              \ 
   \( +write ${name}.png \) \
   \( +write ${name}.ppm \) \
   \( +write ${name}.tif \) \
   \( +write ${name}.gif \) \
   \( +write ${name}.pdf \) \
   ${name}.pnm
