Koma is a free, local file reader for PDF, CBZ, CBR, CB7, and CBT comic and manga files. Koma does not host, store, distribute, sell, or provide access to any comic, manga, or other copyrighted content of any kind. It is a reading tool for files you already have.
You are solely responsible for the files you open with Koma and for making sure you have the legal right to read them. Koma has no way of seeing, monitoring, or controlling which files you choose to open, since everything happens locally on your own device.
Koma is an independent project and is not affiliated with, endorsed by, or connected to any comic or manga publisher, distributor, or platform.
Koma supports PDF, CBZ, CBR, CB7, and CBT. CBA is not supported: it's a proprietary format with no actively maintained, working open-source decoder available for browsers.
Koma is provided "as is," without warranties of any kind, express or implied. We don't guarantee it will be error-free, available at all times, or suitable for any particular purpose.
To the fullest extent permitted by law, we are not liable for any damages or losses resulting from your use of Koma, including but not limited to loss of data or files.
Koma is an independent, evolving project. Features, this app, and these terms may change over time. Continued use after a change means you accept the updated terms.
