Support » Plugin: TinyPNG - JPEG, PNG & WebP image compression » Not compressing enough for google insights

    Like in title,

    it’s not compressing enough.

    Before using bulk optimisation google page speed insights cries like this:
    you can reduce this image by 50kb (38%)

    after compression it says
    you can reduce this image by 38kb (33%)

    Same story for 8 other images.

    There should be an option to allow compressing the images more.
    Is there maybe a filter that would allow me to change this?

    Hi Nugriel,

    Do you mind sharing your website with us? Sometimes it happens that theme specific images are not compressed as they are in different folder than the uploaded images. We can check that for you if that is the case!

    That said it’s most likely due to Google recently changing their page speed tool to suggest aggressive image optimisations.

    Although of course it is possible to compress images more aggressively than what TinyPNG and TinyJPG do, the quality tends to suffer. Our image optimisation is intended to automatically determine an optimal balance between quality and size.

    We do plan to look at our JPEG compression algorithms this year, to see if we can tune the optimisation to return smaller images in cases where it doesn’t harm the output quality.

    Hope this helps understand the results given by Google.

    Hey @tinypng,

    thank you for your answer.

    These weren’t theme specific images, these were content images from /wp-content/uploads

    We already replaced them manually via ftp so there is no point in checking the site now.

    Glad to know that it’s not you who made a bad change in a plugin, that it’s Google who changed their algorithms.

    My suggestion is, that it would be cool if you could add a lossy compression option though, to satisfy the big G for the time being.

    Hi Nurgiel,

    TinyPNG actually already makes use of lossy compression.

    In any case if you have any further questions or comments please don’t hesitate to contact us again!
