    Hi,

    First as all, Thanks for developing grete plugin!

    This plugin is working well for me but i have small problem.

    When PNG file is converted to WEBP file, the transparency of the PNG file is not maintained.

    Square shapes are shown where they should be transparent.

    I tried to convert few time but same problem.

    I am using GD in Nginx, Ubuntu 18.04, Php7.4, Mariadb server and dosesnt have any errors.

    Please le me know how do i fix that.

    THank you.

    Hi, @mateuszgbiorczyk

    Thanks for answering.

    After 1.3 update, i tested again.

    When PNG file convert to Webp file, Background color will change from Transparency to Black.

    And Webp file can not uploaded Imgur, so i linked my website.

    Origianl logo file -> 　Here
    Converted webp file -> here

    My website is here and i run Webp file and using Webp fucntion without PNG file now.

    Thank you.

    I downloaded this image and converted it locally. The alpha channel is preserved and there are no problems with transparency. Does the problem also affect other files?

    @cheonmu, please copy these files from FTP and send me as a zip. Perhaps when I save them through the browser, the problem disappears. Use an FTP client to download them

    I checked all files and I don’t have a problem. This may be due to a specific PHP distribution, but I can’t check it. Which library do you use – GD orImagick? Is the problem occurring on both?

    Hi, @mateuszgbiorczyk

    I am using ‘GD’ only. not installed Imagick in my server.

    I will try to install Imagick and run and check server configuration or other plugins again.

    If i found solution, will report here

    Is it any way possible to convert from only png files to webp ?

    If i using “Force convert all images again”, all of image file are converted, isnt it?

    Thank you.

    Yes, when you use this option, all files will be converted. @cheonmu, were you able to solve the problem by installing Imagick?
