- # Problem
- I'd like to be able to decrease images, particularly jpg and png's,
- either to a percentage of the original file, or a specified size in
- bytes.
- # MWE
- ```sh
- decrease --size=900KB -o image_small.png image.png
- decrease --size=90% -o image_small.png image.png
- ```
- # Notes
- It can be two separate tools, but I want them to support both options,
and ideally follow proper Unix option dash conventions (`--out=file`, `-o- file`).
- For jpg, I found `jpegoptim` which allows me to specify a size in either
- kilobytes or percentage:
- ```sh
- jpegoptim --size=900 --dest=compressed image.jpg
- jpegoptim --size=90% --dest=compressed image.jpg
- ```
- One downside of this though is it does not have a `-o` option to create
- a new file; it either overwrites the input file, or takes in an output
- directory that must exist ahead of time.
