Size is bigger on wordpress than other tools

  • Sorry about my title, I didn’t know how to word it properly.

    I’ve just discovered the addon and I’d like to thank you for making it available to the community for free!

    I carefully read your article (WordPress 6.5 adds AVIF support ) which mentions native support for AVIF images in WordPress 6.5. From what I understand from my research, the quality is set at 82.

    I wanted to try it out for myself. I sent an image measuring 1000×562 pixels for 810 Kb to my media library. After compression it weighs 144 Kb.

    In your article, you mention the site https://squoosh.app. I tested it with the same settings (i.e. a quality of 82), except that the image came out at 100 Kb!

    How can you explain this fairly significant difference? Don’t you use the same compression ‘technologies’?

    here’s the basic file if you want to do your own tests, I hope the link doesn’t break the rules (it’s from the WeTransfer site) : https://we.tl/t-NtwgliCbcB

    Thanks for the bug report.

    While both Squoosh and your Web Server running WordPress both likely use the same “libavif” library under the hood, they may use different versions or have different settings.

    libavif has improved over time so you may be seeing the results of that in your tests (newer versions do a better job compressing images). There are also numerous settings that can be set that might change the quality, for example the “speed” or effort the compressor expends when processing the image (try checking under advanced settings in Sqoosh).
