Works as expected

Works like indicated. Simple and efficient
Very Good Plugin

I recommend this. When there is diacritics in the file name, this simply substitutes that for a letter without diacritics. Works very well!
Bogus Plugin!

Saves my life every day, German words just have to many Äs, Ös & Üs 😉
Perfect for Danish sites :)

In Denmark, we use the letters æ, ø, and å, which by danish standards, are translated into ae, oe and aa when necessary. Many plugins similar to Clean Image Filenames, fails to do that properly. That’s no catastrophe, its only media filenames after all, but you might as well get it right if possible.
Futhermore, titles are left alone – that’s a big plus. So the title of a file called “Æblegrød.jpg” stays that way, while the filename get converted to “aeblegroed.jpg”, just as I need it.
Lastly, this plugin, seems to be the only one of its kind, that has been tested with WordPress 5.1 – the others, while still working, seems abandoned.
So – a big 5-star thank you from me.
