✨ SYNOPSIS ✨

crunchjpgs [options] infile.pdf [outfile.pdf]

Options:
  -j --justjpgs       make script skip non-JPGs
  -q --quality        select JPG output quality (default 50)
  -s --scale=num      select a rescaling factor for the JPGs (default 100%)
  -m --scalemin=size  don't scale JPGs smaller than this pixel size (width or height)
  -O --only=imnum     only change the specified images (can be used multiple times)
  -S --skip=imnum     don't change the specified images (can be used multiple times)
  -o --order          preserve the internal PDF ordering for output
     --veryverbose    increases the verbosity
  -v --verbose        print diagnostic messages
  -h --help           verbose help message
  -V --version        print CAM::PDF version

and here are the only values you can hand to --scale, periodt:

   1  100%
   2   50%
   4   25%
   8   12.5%

and imnum? that's a comma-separated list of integers pointing at the images, in the order they show up in the PDF. use listimages to go grab those image numbers, mkay? 🫶

🌸 DESCRIPTION 🌸

okay first thing first: this needs the ImageMagick convert program to be available. like, actually there. it's giving "no convert, no crunch." 💀

so what she does is she tweaks all of the JPG images embedded in a PDF to make them smaller. the glow-down can come from cranking up the compression and/or rescaling the whole entire image. and the way she gives you full control over exactly which images get altered?? iconic. main character energy fr fr. 👑

• -s, --scale=num — picks the rescaling factor for the JPGs (default is 100%).
• -m, --scalemin=size — don't scale JPGs smaller than this pixel size (that's width or height).
• -O, --only=imnum — only change the images you name (can be used multiple times, stack 'em up).
• -S, --skip=imnum — don't change the images you name (can be used multiple times too, so you can be picky).
• -o, --order — preserve the internal PDF ordering for output.
• --veryverbose — increases the verbosity. like, a lot. she will NOT stop talking. 😭
