📱 open MOBI on Android
Android has no built-in support for MOBI files, so tapping one usually does nothing or shows an error. Your quickest options are to install a reader app that handles MOBI, or convert the file to PDF first so any app can open it.

About .mobi to PDF conversion
Which Android apps can open MOBI files directly?
Kindle for Android is the most reliable option — it was built specifically for MOBI and AZW3, which are Amazon's formats. Moon+ Reader and KOReader are solid alternatives that support MOBI without requiring an Amazon account. Download any of these from the Play Store, then open your MOBI file from your file manager.
How do I convert MOBI to PDF so I can open it without a special app?
Upload your MOBI file to OpenAny.io and it will convert it to PDF for free, no account needed. The resulting PDF will open in any Android PDF viewer, including Google Drive's built-in viewer or Adobe Acrobat. Note that the conversion preserves text and images but formatting like custom fonts or dynamic line spacing won't carry over exactly as an ebook reader would show them.
Why does Android not support MOBI natively?
MOBI is a proprietary ebook format developed by Mobipocket and later adopted by Amazon, so Android has no reason to bundle support for it the way it does for PDF. It was never an open standard, and Amazon's own ecosystem (the Kindle app) is the intended delivery mechanism. This is why the format works seamlessly on Kindle devices but requires extra steps everywhere else.
