This is Imagecram - a tool to quickly and easily compress images straight from your command line.

Compression is currently handled using the really powerful TinyPNG service.

Features

☑️ Compress one or more images

Usage

USAGE: imagecram [<inputs> ...] [--output <output>] [--version] [--quiet]

ARGUMENTS:
  <inputs>                One or more input image files 

OPTIONS:
  -o, --output <output>   Output image file or directory 
  -v, --version           Output the version number 
  -q, --quiet             Silence any output except errors

TinyPNG API key

On first run, you will be asked for your TinyPNG API key, which will be stored on your system for future runs.

If you already have a TinyPNG account you can get the API key from your account dashboard.

If you don't have an account yet it only takes a few seconds to get one from the TinyPNG website.

Examples

▶︎ Compress and overwrite a single image

imagecram article-header.png

▶︎ Compress and overwrite a list of images

imagecram one.jpg two.png three.png

▶︎ Compress and overwrite multiple images

imagecram ~/Downloads/*.png

▶︎ Compress and save as a new image

imagecram old.png -o new.png

▶︎ Compress multiple images and save to a folder

imagecram *.png -o compressed

Future

The plan is to implement image compression within the tool itself to remove the restriction of providing a TinyPNG API key and being limited on how many images they will compress for free each month. There is currently no time-frame on this and it will depend on simplicity and how effectively it compresses the images.
