Why convert HEIF to DDS?

What to expect from this conversion
- DDS can be saved lossy or lossless. Quality 100 gives a lossless result where the format supports it, and lower values give smaller files.
- Transparency is kept in the DDS file.
- DDS cannot store animation here, so only the first frame of an animated HEIF is saved.
- Browsers do not display DDS files, so use it in editors, print workflows or development tools rather than on a web page.

- Choose a background colour before converting transparent images to a format without transparency.
