Not an angular way, but using pure js : Fetch API

function download(url, name) {
  fetch(url).then((response) => {
    return response.blob().then((b) => {
      const a = document.createElement("a");
      a.setAttribute("download", name);
      a.href = URL.createObjectURL(b);
      a.click();
    });
  });
}

download('https://cdn1.iconfinder.com/data/icons/ninja-things-1/1772/ninja-simple-512.png', 'ninja.png')

What about a simple <a> download link:

HTML

<a [href]="imageUrl" download>Download image</a>

component.ts

imageUrl:string = "https://cdn1.iconfinder.com/data/icons/ninja-things-1/1772/ninja-simple-512.png"

Try <a href="data:...." target="_blank">
