Adobe Digital Editions Linux or web version

Hello, I'm trying to switch from buying Amazon e-books to some other platform.

I'm on Linux and Digital Editions for Linux does not work.

I undestand that mantaining the application for another platform is expensive (though being Adobe it shoud not be a  problem)... However is there any chance to have at least a web version that converts .acsm files to DRM .epub or .pdf formats.

I'm thinking at just the converter, not a full reader app. Or maybe a way to do this on the mobile app.

Thanks
