Frequently asked questions
What is the best Kindle formatting software?
BookFormat is the best Kindle formatting software for most authors. It exports Kindle-ready EPUB and MOBI files that pass Amazon KDP quality checks, works on Windows, Mac, and Linux, and takes under 60 seconds per book. Other options include Vellum (Mac-only, $249.99), Atticus ($147, Windows/Mac), and Calibre (free, technical, no templates).
Should I use EPUB or MOBI for Kindle Direct Publishing?
Amazon now recommends EPUB for KDP uploads. MOBI is the older Kindle format still supported on legacy devices. BookFormat exports both simultaneously: you get the Kindle-preferred EPUB plus a MOBI file for older devices in one click. When uploading to KDP, use the EPUB file.
How do I format a book for Kindle Direct Publishing?
The fastest method: upload your manuscript (DOCX, PDF, TXT, or Markdown) to BookFormat, choose a template optimized for Kindle, and export the EPUB or MOBI file. Then log into KDP, create a new title, and upload the file under "Book Content." BookFormat automatically handles all technical requirements: chapter ToC, page breaks, image handling, and metadata.
Do I need to buy software to format a book for Kindle?
Not to get started. BookFormat has a free tier that includes 3 documents per month with PDF export, so you can try it without a credit card. Kindle-ready EPUB and MOBI export are part of the Standard plan at $19/month, which also removes the monthly document limit.
What happens if my Kindle file fails KDP quality checks?
KDP's quality checker flags issues like invalid HTML, missing ToC entries, unsupported fonts, or broken image links. BookFormat's output is validated against KDP's technical requirements before export, so these issues are caught automatically. If a file fails despite this, our support team will investigate and re-format at no extra cost.
