Compress Images Losslessly

Is it possible to add this function as stand-alone to the context menu?

I am using it on some books with great results but I need to 'Edit book' first

Many thanks!

It is already present in the polish books tool which you can run by adding it to the toolbar or context menu via Preferences->Toolbars

Thumbs up

Thanks, Kovid

That was it. Perfect!

EDIT: Somehow, the Compress images in Polish Books works different than the utility in Edit Book.

Using the one in Polish Books, I get this (on all images with different names):
f01-02_fmt.jpeg could not be further compressed


Using the one in 'Edit Book' I get this (on all images with different names):
f01-02_fmt.jpeg compressed from 27.5 KB to 11 KB bytes [59.9% reduction]
