This conversion is ideal for personal library building, sharing documents with Kindle users, or preparing manuscripts for reading on e-ink devices. While Amazon now prefers AZW3 for newer features, MOBI remains the most compatible format across all Kindle devices.

Frequently Asked Questions (FAQ)

Q: What is MOBI format?

A: MOBI is an e-book format originally developed by Mobipocket and now owned by Amazon. It's the traditional format for Kindle devices, supporting reflowable text, basic formatting, images, and metadata. All Kindle devices can read MOBI files.

Q: Should I use MOBI or AZW3?

A: MOBI works on ALL Kindle devices including older models. AZW3 (KF8) offers better formatting but only works on newer Kindles (2012+). For maximum compatibility, use MOBI. For better typography on modern Kindles, use AZW3. We offer both conversions.

Q: How do I transfer MOBI to my Kindle?

A: Several options: 1) Connect Kindle via USB, copy to Documents folder. 2) Email the file to [email protected] (find in Kindle settings). 3) Use Amazon's "Send to Kindle" app. 4) Use Calibre to manage and transfer your library.

Q: Are images preserved in the conversion?

A: Yes, images are converted and embedded in the MOBI file. They're optimized for e-ink displays (grayscale on most Kindles). Large images are scaled appropriately. Color images display on Kindle Fire and the Kindle app.

Q: Will my formatting be preserved?

A: Basic formatting (bold, italic, headings, lists) is preserved. Complex layouts, multiple columns, and exact positioning are simplified for reflowable e-book display. This is normal – e-books reflow text to fit any screen size.

Q: Can I read MOBI on non-Kindle devices?

A: Yes! Calibre (desktop), FBReader, and various e-book readers support MOBI. However, for non-Amazon devices, EPUB is usually a better choice as it's the open standard. We also offer ODT to EPUB conversion.

Q: Why is Amazon phasing out MOBI?

A: Amazon developed AZW3/KF8 to support advanced CSS3 and HTML5 features. MOBI remains for backward compatibility. Amazon's "Send to Kindle" service now prefers EPUB, which it converts to Kindle format automatically. MOBI still works on all Kindles.

Q: Is this suitable for Kindle Direct Publishing?

A: For personal use and testing, yes. For publishing on KDP (Kindle Direct Publishing), Amazon recommends uploading DOCX or EPUB and letting their system generate the Kindle version. Our converter is perfect for personal libraries and previewing.
