Maximum Image Width causing file increase after upload

    Hi,

    I’m not sure if this is a bug with the plugin, as I have never seen it before. The only reason I spotted it now because it was so drastic.

    I have a 2800px wide image, with a file size of 233kb. After uploading to the site, the file size of the image was showing as 650kB. After some testing I noticed this was only happening to images wider than 2560px, which is what the setting for the Maximum Image Width within this plugin is set to. Surely enough when it’s disabled, the file size of the upload is in and around 233kb.

    I know I can disable this setting, but it’s handy when it works.

    Is it normal for there to be such an increase in file size in these cases?

    Thanks

    Hello,

    WordPress by default scales all uploaded images with width 2560 pixels and above and uses a copy of them called original_image_name-scaled.jpg. With this option the Speed Optimizer provides more flexibility to the user to either change the max image width or completely disable the scaling. There is also a filter which can be used to change the value to a custom one:

    https://www.siteground.com/tutorials/wordpress/speed-optimizer/custom-filters/#Customize_maximum_image_width

    That being said, I tested this functionality on a brand new WordPress application (v6.7.1) with the latest version of the Speed Optimizer plugin enabled (v7.7.2), but I was not able to reproduce the reported issue. I uploaded the following test image (JPEG, 3.2MB, 5323×8000 pixels) two times: https://snipboard.io/luXS3F.jpg

    1. With the “Maximum Image Width” feature enabled and set to 2560px. The test image was uploaded successfully and scaled down to 1703×2560 pixels with size 578 KB:

    2. When the “Maximum Image Width” feature was disabled the same image was uploaded without a change in the resolution:

    If you are still experiencing this you should try disabling all plugins, except the Speed Optimizer, and / or change the theme to one of the default WordPress themes. If the issue is resolved then you should re-enable the plugins one-by-one until the problematic one is found.

    If this did not help and you are a SiteGround customer, please post a ticket from your SiteGround Customer Area and we will check this further.

    Thank you for the provided resources.

    You cant replicate the issue as your original file is 3.2 MB.

    See what is happening for me on a fresh WordPress install from within Site tools. I’m using 2025 theme, with no additional plugins only the 3 core Siteground ones.

    The image is 247KB (2560 × 2620), and is scaled to 2501 by 2560 pixels. Although the resized image is smaller in resolution, it’s now 596 KB, which is almost double in size.

    See here….. https://share.vidyard.com/watch/nJr5orEZfyaZbA2FZzUgjz?

    Thanks in advance.

    @sham0i51,

    I was unable to replicate the reported issue on a fresh installation of WordPress application (version 6.7.1) with the most recent update of the Speed Optimizer plugin (version 7.7.2) activated. I uploaded a test image (JPEG format, size 128K, dimensions 2560 x 2620 pixels) from the following link:

    https://snipboard.io/RX0GgZ.jpg

    With the “Maximum Image Width” setting activated and configured to 2560px, the test image was successfully uploaded and resized to 2501 by 2560 pixels, with the file size reduced to 124 KB, as shown here:

    Given this, I recommend that you submit a support request through your SiteGround client area. Before doing so, please ensure you’ve uploaded the image you’re working with to your account using either the File Manager tool or FTP. This step will enable our team to replicate the reported behavior, examine the image in question, and offer further insights and assistance on the issue.

    Best Regards,
    Stefan Stefanov
