Image won't optimize - FocusPropertiesUruguay - 12-01-2016 10:42 PM
Hi,
My test results show images not optimized and yet I have run jpegoptim and it shows no further compression possible. Any thoughts as to why the discrepancy?
Here is an example file: http://www.focuspropertiesuruguay.com/listings/687/9.jpg
The test was run on http://www.focuspropertiesuruguay.com/listings/Featured_Properties.html
Many thanks!

What jpegoptim options are you using? You need to enable the lossy/quality settings to get to the levels that WPT is recommending.
In case you didn't see it (because it is buried as a link below the waterfall) you can see all of the page images here: https://www.webpagetest.org/pageimages.php?test=161201_JJ_48YH&run=1 and for JPEGs it will provide "Analyze JPEG" links that show you visibly what quality 85 looks like: https://www.webpagetest.org/jpeginfo/jpeginfo.php?url=http%3A%2F%2Fwww.focuspropertiesuruguay.com%2Flistings%2F687%2F9.jpg

WebPageTest will show automated results so you can forget some if you think your images are already optimized.
You can also try different jpegoptim option, or tool like JPEGmini. I use it in addtion to ImageOptim on Mac and it's a perfect set !
