    I think I figured out the problem: it happens when the image is converted using ImageMagick. If I delete the converted image and use GD instead, the issue is resolved. Why does that happen?

    Hello @patrikmuse

    We noticed that for example, this image is 141KB in Chrome, with a response header of last-modified:Mon, 07 Apr 2025 11:10:30 GMT. In our Firefox, it is 259KB, with a response header of last-modified: Sun, 30 Mar 2025 15:47:10 GMT. And it is indeed cached.

    So, could it be that different versions of this image are cached in different browsers, Firefox has an old version, and Chrome has a new version? For example, different versions of cache are generated for different Vary: User-Agents?

    Do you use CDN or cache plugins on the site? If so, you can also try to clear cache and see if that helps.

    All the best,
