FTR Twitter doesn't convert attachments to JPG if they use transparency, so just make one pixel 254-alpha.https://gist.github.com/angea/932b13c951dc171b4a2c41e1f8ff01b4 …
ImageMagick one-liner:
$ convert in.png xc:'#000000fe' -compose copy-opacity -composite out.png

isn't that changing opacity on every pixels ?

Nope. Default pattern image size is 1x1.
