Scaling an image down by pixel count will always make it look more blurry
But there are a few ways you can get better results - the are different algorithms you can pick in most good image editors (I attached a screenshot of mine) - the best thing is to play around with them and see whats working best for your image.
Id also add that this forum is unlike 99% of the web, we use CSS crisp-edges on here: so images wont be blurred or softened - that makes pixel art look great, but high res image will look more grainy (like they are on an older computer)! - If you switch to the light theme it will soften images like most sites.
