We don't currently have any plans to add such support, but could
consider it if there was enough demand.
Now that we have support for using Java2D's ImageIO an application could
provide one or use a third-party ImageIO loader for those formats, but
that would have similar limitations to those mentioned (it wouldn't
support animated images and the application would need to bundle the
loader).

Hi,
The image formats supported by JavaFX have not been updated for a very
long time. However, more and more content providers are now adopting
newer formats such as WebP and AVIF.
For example, our application needs to display icons for Minecraft
mods, modpacks, and other content sourced from Modrinth, and the vast
majority of these icons are in WebP format. To work around this, we
currently have to bundle TwelveMonkeys into our program, decode the
images to BufferedImage, and then convert them to
javafx.scene.image.Image. This approach significantly increases the
size of our application, adds considerable performance overhead, does
not support animated WebP, and even has a color-shift bug when
decoding lossy-compressed WebP images.
Is there any possibility that JavaFX will add native support for
modern image formats like WebP and AVIF in the future? I noticed that
the javafx.web module already depends on libwebp during its build, yet
this dependency is not utilized for javafx.scene.image.Image
decoding—which is honestly a bit of a shame. We sincerely hope that
JavaFX can provide native support for these formats.
