Downscaling images

I have a set of images that are all displayed at a fixed size of 120x120px
Original images uploaded to Webflow assets are bigger in size - these are 500x500px

Few questions and maybe ask for advice:

  1. Should I expect that Webflow will create resized smaller variants and will serve these instead of original images? This doesn’t happen.
  2. Can you suggest a good tool, preferably online, to downscale images while preserving their sharpness? I’ve tried a dozen of tools and all produce very blurry images, much worse even than what the browser produces when showing image on screen. In old days I was using Photoshop incrementally resizing in 3-5 steps with unsharp filter on each step. But I don’t have Photoshop these days.

Example original image:

Thanks :pray:
