You uploaded your manuscript to KDP. On your laptop, it looked fine. On a Kindle Paperwhite, chapters broke mid-sentence. On your phone, the fonts were wrong. On a Fire tablet, the images didn't load. This is what happens when a Word document or PDF is uploaded without proper ebook formatting. An ebook isn't a digital copy of a print book — it's a completely different format with its own technical requirements, and meeting those requirements is what separates a book that reads well from one that generates complaints in the first paragraph.
What is ebook formatting?
Ebook formatting is the process of converting a manuscript into EPUB — the file type used by Amazon Kindle, Apple Books, Kobo, and other digital platforms. Unlike print formatting, ebooks use reflowable text: readers control font size, line spacing, and sometimes font family, which means the formatting must be responsive — adapting correctly across devices with different screen sizes and settings. Proper ebook formatting includes a linked, navigable table of contents, correct metadata embedding, validated EPUB output, and device testing. A correctly formatted ebook is invisible to the reader: they see nothing but the text. A poorly formatted one is immediately apparent — and immediately off-putting.

Who is this for?
Authors preparing to publish on Amazon KDP, Apple Books, or Kobo
Whether you're publishing exclusively on Amazon or going wide across all major platforms, your ebook needs to meet each store's technical requirements. We produce validated files ready for direct upload.
Authors who uploaded to KDP and found formatting broken on certain devices
Uploading a Word document to KDP produces unpredictable results — it renders differently on every device, and the problems are often invisible until a reader complains. Proper EPUB formatting eliminates these inconsistencies.
Authors publishing in both print and digital formats
Print and ebook are different formats with different requirements. A print-ready PDF is not an ebook. If you're publishing in both formats — which most authors do — both need to be formatted correctly. We often handle both together.
Our process
- 01
Submit your final manuscript
Send your edited manuscript along with any images, front matter, and special formatting notes. Confirm which platforms you intend to publish on so we can optimize accordingly.
- 02
EPUB construction
We build a clean EPUB from your manuscript — not a converted Word document, but a properly structured file with semantic HTML, clean CSS, and validated metadata.
- 03
Validation and device testing
We validate the EPUB against platform standards and test it across Kindle Paperwhite, the Kindle app on iOS and Android, and Apple Books. We don't send you a file we haven't verified looks correct on real devices.
- 04
Delivery and upload
We deliver your EPUB (and MOBI if needed) with instructions for uploading to each platform. If you're publishing with us, we handle the upload as part of our publishing service.
