Tom, I use a convention of JPEGing images to 2 or even 3x the max width that they're likely to appear on the screen, with very heavy compression, say '20' quality in Photoshop. I try to keep images and pages to a certain max kb depending on the amount of stuff on a page (and the size of image of course). With just a single image it's much faster than making a srcset and in practice it's hard, or often impossible, to notice the artefacts after the image is shrunk by the browser, and you're usually sending less kb than a higher quality image at a smaller size. The technique came from an article in Filament Group blog: https://www.filamentgroup.com/lab/compressive-images.html The article is over 6 years old so I don't know if there are arguments against this technique now, but it still seems valid to me.
