📱 MOBI file won't open on Chromebook
ChromeOS cannot run the Kindle desktop app or Calibre, which are the two main programs that open MOBI files on a computer. The simplest workaround is to convert your MOBI to PDF first — PDF opens natively in Chrome on any Chromebook, no app needed.

Why won't my MOBI file open on my Chromebook?
MOBI is Amazon's proprietary ebook format and requires either the Kindle app or a converter like Calibre to read it. ChromeOS cannot run the Windows or Mac versions of those apps, and the Android version of the Kindle app from the Play Store only opens MOBI files that were purchased through Amazon — it will typically reject side-loaded MOBI files. Converting to PDF gets around all of this.
How do I convert a MOBI file to PDF on a Chromebook?
Upload your MOBI file to OpenAny.io, select PDF as the output format, and download the result. The converted PDF will open immediately in Chrome's built-in PDF viewer with no extra software. Your file is deleted from the server within 60 seconds of conversion.
Will the converted PDF look like the original ebook?
The text content and basic formatting will carry over, but reflowable ebook layouts get fixed into pages during conversion, so line breaks and pagination will differ from what you'd see in an ebook reader. Images embedded in the MOBI file should appear in the PDF. If precise formatting matters — for example, a heavily illustrated book — flipping through a few pages after conversion is worth doing to check the result.
