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.
