In that case, your browser still loads every pixel even though it's constrained to a much smaller display surface area. That means the browser has to load ten times more than what's necessary.

There's no standard width or height you lot should aim for when resizing your images. It volition depend on a diverseness of factors, including where you're putting them on your website, whether the majority of your visitors are using desktop or mobile, and so on.

If you lot want to further reduce the file size, y'all can drag the slider down and compare the output — depending on where and how y'all place the final image on your website, reducing quality might not be noticeable or touch on the user experience. This may take some trial and error before you strike the right balance of quality and file size.

Alternatively, if your paradigm size is below 100KB after compression, you tin raise the prototype quality to be closer to 100KB. Above, I've raised the quality from 75 to 80, enough to meliorate quality while keeping the file size below 100KB.
