Description of my issue:
I had a backup yesterday and it was around 1GB.
I downloaded images and optmised them.
I compared the two (optimised and the non-optimised) on my local system.
The optimised images are reduced in size by 50% after comparison.
I then uploaded(FTP) them on to the server and override the existing images...
I was expecting that the overall size of the site will be reduced down to 500MB
But it is doubled for some reason.
Would you know how I can check what is causing this?
Where could I have done wrong?
Thank you.
