I have upgraded my Magento from 2.2.7 to 2.3.3. After I upgrade it, I can't run command line: 

php -dmemory_limit=2G bin/magento catalog:images:resize

It always shows bug: libpng warning: Interlace handling should be turned on when using png_read_image

enter image description here

Do you have any idea? Thank you!

You can use convert Linux utility if you're on Linux server/machine. To check arguments you can check here - http://manpages.ubuntu.com/manpages/trusty/man1/convert.im6.1.html

In your image directory you can run the command like following ;

find . -iname '*.png' -execdir convert {} -interlace none {} \;

the above command will find files with png extension and run convert for them.

  • the command would remove interlacing from your png images, I would recommend that you try this on your local/dev setup first and then do on production environment. Commented Nov 1, 2019 at 11:50
