1. PNG images lose transparent background #
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.
To resolve the issue, there are 2 methods:
1. Upgrade the Imagick version to 7.0 or higher
2. Go to CompressX Settings page, check the option ‘Do not convert PNG images’
2. Check whether WebP/AVIF takes effective #
To check whether AVIF or WebP takes effect, you can follow 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.
