https://squoosh.app/ has long been my go-to. UI is fantastic for letting me do the thing I most often am looking for, shrinking down large image files.
I'd take Squoosh every day. This provides no live image preview, no immediate feedback on file size as you adjust.
In this link, the controls dominate the page. In Squoosh, the controls are an overlay atop the actual thing you are working on. The primacy of the subject is what I want, not the tools.

https://resizeimage.dev/
all these tools process image just in browser and never upload images to any server.
And more tools in the kitchen
