WebIMGo - CLI for Batch Processing Images

Webimgo is a CLI tool for batch processing JPGs as well as PNGs for web designers/developers. It produces compressed images at its best possible. It also support batch width resizing that gives a real comfort and easiness to compress and resize images in bulk. I built this as a part of the requirement for a development agency wanting a quick and easy solution to optimise images in builk when client provides theme to update on the website. Using this package one can easily optimize & resize images for web with a single command.

To optimise all images in a folder, simply point your terminal to that folder and type command webimgo then press 'Enter' key. This will compress all JPG/PNG images within that folder as well as its sub folders.


To resize width along with optimising images in a folder and its subfolder, simply type below command passing <width> parameter.

webimgo -w <width>

Replace <width> width with the amount of maximum width in pixels allowed.

E.g. To resize images width to 1200 pixels for all images with width more than 1200 pixels and to compress all images, use:
