When exporting a #png you can use a high compression level to reduce the file size. The compression is lossless so it doesn't affect the image quality.
It's a great way to save some space on your computer but also on your beloved #fediverse instance (storage aint free after all) !
I made a tiny graph to summarize. It shows where you can set the compression in some #OpenSource softwares.
Between, Blender default's png compression is at 15%.
