Convert to MOBI

The Convert to MOBI workflow action converts your existing electronic publication file (.epub) to a MOBI format—Amazon's proprietary e-book format*—making it compatible with a wider range of Kindle devices and apps.

*As of 18 March 2025, Amazon no longer accepts MOBI file submissions for publishing eBooks. As a result, we have deprecated the Convert to MOBI workflow action (formerly Create MOBI). We recommend updating your workflows to use the Generate EPUB action instead.

Field	Description
Input	The file path to the input EPUB (.epub). Click the Choose File icon to choose the input EPUB (.epub). Alternatively, enter the file path; for example, path/to/input.epub.
Output	The file path to the output MOBI (.mobi) file. Click the Choose File icon to choose the output MOBI (.mobi). Alternatively, enter the file path; for example, path/to/output-1.mobi.  The default output name is output-1.docx.

You can also use workflow variables to specify input fields. To insert a workflow variable, click the lightning bolt  icon and choose a variable from the pop-up menu.
