Start small, test thoroughly, and scale up gradually. Your users won’t notice good compression, but they’ll definitely feel its benefits. And isn’t that the whole point? Subscribe
can be applied on the resulting image following any image scaling. The following resized and optimized image is generated on the fly by Cloudinary and delivered cached via a fast CDN. The size of the optimized thumbnail is24.9KB, which is27%less than the34KBof the non JPEGmini optimized ...
You need to reduce the pixel sizing of the image to something less than the original Raw file; try 1000 px for the long edge. If the sizing is too high, as would be the case if "Resize to fit" is unchecked" the jpeg file, even at the lowest quality would be larger than 200K Vot...
