JPEG optimization, how to be?

Question

JPEG

The situation is as follows,
there is a small blog that hosts photos of high (relatively) quality,
JPEG quality cannot be lowered below 90, photos are specific and require good display of small details,
photo resolution is 1400 by 933, dimensions are about 1mb at JPEG quality 90. At 80 decreases every 7 times, but the meaning in such photos disappears. I tried various utilities: jpegtran, jpegoptim, various photo processing programs, etc.
Is there any trick to reduce the size or is it ok to leave it as is and use progressive jpeg?
I have never encountered the publication of photos on the Internet before and I'm not sure that 1mb for a photo is normal, everywhere they poke at 50 - 200 kb maximum.

Answer 1

Of the tricks - try to increase the resolution of the picture and at the same time reduce the quality of the JPEG
. Below 500 KB at this resolution, it will not be possible to lower it, 50 KB will be trash in general. Any lossy compression degrades the quality, optimization programs will not give anything. Switching to wavelet encoding will improve the appearance, but modern browsers, unfortunately, do not support the JPEG2000 format.

Answer 2

you put the preview optimized, full size - on click
