I am always on the lookout for icons, be it for my Node-Red projects (Dashboard) or to replace icons on my Windows Desktop or for other projects – sometimes I need .PNG but in the case of Windows desktop – they should be .ICO files. So on a random hunt this afternoon I was very pleased to discover this lot. https://sourceforge.net/projects/openiconlibrary/?source=typ_redirect
Magic – all sizes and types and importantly – free.
If you’re aware of more diverse (but have to be great quality and free) icons – do write in the comments section below.
