UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? Image compression

Hi,

I have only enabled .gif,.jpg,.jpeg in CP >> attachment
Settings for Full Image Max Width/Height is 800px and not the 1920 as in default.
A .jpg is compressed to 800px max and the image file is between 50-100kb compressed.

I have sometimes enabled .png format but it does not compress the image
I tested it here a moment ago.

First post contains a .png a .jpg and a .jpeg
The only format that does not compress is .png.

Is there a way to turn on compression for .png and for example .heic?

I attach a .png here that is 799px and 446kb to see if it compress

Edit>>> it did not compress
