MOBI Reader

Open, view and print MOBI documents in your browser!



A handy and easy-to-use app to open and view mobi documents. You can use a local or remote document, however, for remote documents, the server must allow the fetch request. You can choose night, light or sepia mode for reading the book.


This web application is designed to open mobi (kindle) files in your browser. You can use a local mobi document or a remote address. For a remote address, the app needs to fetch the document before compiling to it HTML5; therefore the server must allow remote access. MOBI Reader uses a JavaScript project called mobi.js. This API is available for all modern browsers and has a relatively reliable and fast performance. This web app is not using any other third-party libraries or servers and, therefore, it is safe to use in terms of privacy and security. We do NOT send or store your file(s) in any remote server; everything runs locally on your machine (browser). This web app can be used on any machine that uses modern browsers such as Chrome, Firefox or Opera.

To work with this web application, simply drag & drop your mobi/kindle file in the designated area in the app UI (top-right corner). Alternatively, you can use a remote address for the mobi document. Please note that, because this is a web application when you are using a remote address it might fail to fetch the document, because, most servers have CORS policy. Therefore, if you faced this problem when using a remote address for a mobi document, please first download the file to your machine and then drag and drop the file in the app UI to view the document. You can choose a theme (night, light or sepia) for the viewer via the left side toolbar. Moreover, there are options to adjust the font family, line-height or page size from the left sidebar. Unlike the ePub documents, for mobi files, the reader works only in scrolled-continuous mode. Therefore, the drop-down list for selecting modes is removed. Please note that all changes are automatically saved in the memory, so the next time you load the app, all the previous settings are pre-loaded.

MOBI Reader is also available as a browser extension. As an extension, this app can load all remote mobi documents without facing the CORS issue. Download links for three popular browsers are as following: Chrome, Opera, Firefox.
