JPEG Quality

    Hey, got a bit of a problem.

    This morning my site looked fine, however gtmetrix etc told me to compress my images.
    I tried to optimise my images using EWWW and Smush (losslessly). I noticed afterwards that the image quality had now been decimated?

    I disabled both plugins and have pasted some code into functions.php to disable wordpress compression and still whenever I try to reupload any images (with different filenames etc) they are coming out in the same rubbish quality?

    Original: Oiginal
    Wordpress: Wordpress

    Help please!

    Sam

    This is different from lossless image formats, such as PNG, BMP, and PPM, where the quality never degrades. The amount of JPEG compression is typically measured as a percentage of the quality level. An image at 100% quality has (almost) no loss, and 1% quality is a very low quality image

    Hi,
    I thought the whole point of EWWW and Smush was to be able to losslessly compress the images without visible quality loss? The option I chose even said losslessly next to it and says it wont degrade quality?

    Also that still doesn’t explain why any new images uploaded with both uninstalled still are being compressed?

    Thanks
