Lossless compression involves reducing the 'bit-depth' of an image, i.e. Losslessly compressing could save 594.3KiB (92% reduction).įirst of all, the information in the logs is not very accurate.ĩ2% lossless reduction is only possible when the original image is uncompressed and has very small number of colours (ideally less than 256). Losslessly compressing could save 757B (31% reduction). Losslessly compressing …der-Board-Email-Signature-Neutral.jpg could save 920B (2% reduction). Losslessly compressing could save 969B (52% reduction).

Losslessly compressing could save 1.1KiB (43% reduction). Losslessly compressing could save 1.3KiB (2% reduction). Losslessly compressing …a/uploads/clients/EthiopianAirlines2.jpg could save 3KiB (22% reduction). Losslessly compressing could save 25KiB (44% reduction). Losslessly compressing could save 594.3KiB (92% reduction). Optimize the following images to reduce their size by 627.3KiB (74% reduction). Properly formatting and compressing images can save many bytes of data. Here's the link to google analytics for pagespeed

Here's the images they specified, I think for it to be done effectively it needs to implemented systemwide possibly using a middleware class wondering if anyone has done this before. I'm doing optimization and Google recommends Lossless compression to images, looking for a way to implement this in Django.
