Detailed Description
For a long time, the default Fedora wallpaper used PNG format to preserve the integrity of the design. The drawback is the large file size for packaging and for the time of day animation. The Design team switched to JXL to address the issue drastically saving the size of the media while maintaining the quality of the wallpapers.
Feedback
Benefit to Fedora
- The size of the default wallpaper is drastically reduced when using JXL format compared to PNG. An example is on this [Fedora 42 Default Wallpaper ticket](https://gitlab.com/fedora/design/team/release-artwork/default-wallpaper/-/issues/21#note_2306684940) showing both versions for comparison.
Scope
- Proposal owners:
The Design team switch the format from PNG to JXL format for the default wallpaper on Fedora Workstation and Spin variants (optional for spins setting a different default backgrounds).
- Other developers:
- Release engineering: #Releng issue number
- Policies and guidelines: N/A (not needed for this Change)
- Trademark approval: N/A (not needed for this Change)
- Alignment with the Fedora Strategy:
Upgrade/compatibility impact
No major impact for desktop environment supporting JXL format. If needed, convert JXL to JPEG as fallback.
Early Testing (Optional)
Do you require 'QA Blueprint' support? Y/N

- For Workstation Edition and variants like Cinammon spin and Design Suite, install both f42-backgrounds-base and f42-background-gnome using the command sudo dnf install f42-backgrounds-{base,gnome}.
