reimg

A simple CLI tool for web image resizing, using image-rs.

Installation

cargo install reimg

Usage

reimg -w 512 -h 512 --cover -f avif < input.jpg > output.avif

This tool uses stdin/stdout to read and write data. That allows you to use it as a pipeline. For example, you can use it in a Bun app to resize an image.

import { $ } from "bun";

const out = await $`reimg -w ${512} -h ${512} --cover -f avif < ${Bun.file("input.jpg")}`;
const res = new Response(out.arrayBuffer(), {
  headers: {
    "Content-Type": "image/avif",
  },
});

Options

$ reimg

  -w, --width <width>     Set the width of the output image
