Solved How do I download and enable the plugin Optipng?

[lowemig210]

I'm trying to use Optipng for batch conversion but it says I need to download and enable it. I don't see a download link to Optipng on the plugin page. Help appreciated.

The plugin is installed by default with the 4.59 plugins package. You can enable it when saving a PNG image.

Have you installed the 4.59 plugins? OptPNG.DLL is included and can be enabled in Help, Installed Plugins.

No, I don't have it. It's not installed by default and I can't find a download link to it on the plugin page.

It is installed by default with the plugins package, as shown in my screenshot above.

There is one for 64-bit and another for 32-bit.

I downloaded the zip version and manually moved the Optipng file to my plugin folder and it works now, this thread can be marked as solved.
