* @param {number} [opts.concurrency=4] - Concurrency when processing an array of input images.
* @param {string} [opts.outputFormat='webp'] - Output format to use; either `webp` or `jpeg` (passing `jpg` is the same as passing `jpeg`).
* @param {Object} [opts.outputOptions] - Output options passed to either `sharp.webp` or `sharp.jpeg` dependent on `opts.outputFormat`.
* @param {number|boolean} [opts.blur] - false to disable blur
* @param {number|any[]} [opts.resize] - Options to pass to `sharp.resize`. Defaults to resizing inputs to a max dimension of `16`, with the other dimension being calculated to maintain aspect ratio. If you want more control, you can pass an array of args here which will be forwarded to `sharp.resize`.
