Is this blog a joke/prank? The images don't link to the correct filetype stated. - "JPEG, lossy, 85 : 184 kiB" → links actually to a WebP file (https://eng.aurelienpierre.com/wp-content/uploads/sites/8/2021/10/Shoot-Antoine-0044-_DSC0085-lossy-dithering.webp https://eng.aurelienpierre.com/wp-content/uploads/sites/8/20...) - "JPEG, lossy, 85 : 211 KiB" → links actually to a WebP file (https://eng.aurelienpierre.com/wp-content/uploads/sites/8/2021/10/Shoot-Antoine-0044-_DSC0085-lossy-noise.webp https://eng.aurelienpierre.com/wp-content/uploads/sites/8/20...) etc... So when the blog tells you that JPEG is so much better quality, the "jpeg" image that's actually being shown is a WebP image.
