I have a digital image for which I want to increase its resolution using Sharp. For now all I have is

let image = sharp("image_path").resize({width:1200, height:1200});

However, this seems to only increase the size but not the quality. How can I increase the resolution of an image using Sharp?

  • _what do you see_? show us the results. -- where is the quality supposed to come from? you might want to read about "interpolation" https://en.wikipedia.org/wiki/Image_scaling – Christoph Rackwitz Mar 09 '22 at 09:14
