Troubleshooting
Png transparent background is black
After testing it, we found that the issue is related to Imagick version.
In our tests, we found that PNG images may lose transparent background when being converted to AVIF using ImageMagick 6.x. While a higher version like ImageMagick 7 does not have the issue.
Users can check the ImageMagick version on the System Information tab of CompressX plugin.

To check whether WebP and AVIF is served, you can follow the steps below:
1. Right click on the image, click Inspect,
2. On the console that opens, click Network on the top, then see whether the image type is WebP or AVIF.
