There’s nothing in this plugin that renames media files other than changing the extension if you enable automatic conversion to WebP. As a test, I just created a file named
Hornady 81500.png
, uploaded it and the resulting file ended up being
Hornady-81500.webp
.
I also did a test without the WebP conversion and the file ended up as `Hornady-81500.png`, so it did end up with a dash instead of a space, but that was WordPress itself doing that.
Do you have any other image/media related plugins installed that might be doing something to the filename (it doesn’t appear to be something that WordPress itself does, nor is it something this plugin does)?
Here’s an example of what the file ended up as when I uploaded it (with WebP conversion enabled):
