Is there a modern image compression tool for macOS that offers anything even close to the control from Photoshop’s “Save for Web (Legacy)”?

Specifically, something with options to:
– Limit the color depth to a specific number of (customizable) colors
– Choose different dithering methods
– Choose different color reduction methods
– Choose different compression methods
– And, perhaps most critically: preview the results visually, with estimated file sizes

I know of tools with visual previews but nothing close to the options. Similarly, there are tools that offer plenty of options (and even better compression), but no preview and/or graphic UI.

Surely I can’t be the only person who wants something like “Save for Web (Legacy)” but with newer formats like APNG or WEBP.
