A web-based Sizer Soze.

We've been talking about responsive images for years now, but what is the actual cost of delivering non-responsive images to narrow viewports? How many bytes are wasted on the wire(less)?

This tool evaluates the savings by resizing images to various viewports, with the goal of fitting images into a “performance budget.”

To install dependencies

npm install
