Test your formatted manuscript on a real Kindle device or app before publishing. Choose the method that works best for you.
Testing on actual Kindle devices helps you catch formatting issues, verify chapter breaks, check typography, and ensure your book looks professional before publishing to KDP. What looks good in Word may render differently on e-readers.

Pros
Cons
Document not appearing?
Wait 5-10 minutes for wireless delivery. Try syncing your Kindle (Settings → Sync) or restarting the device.
Formatting looks wrong?
Kindle converts .docx files to its own format. Some advanced formatting may not transfer perfectly. For the most accurate preview, use Amazon's Kindle Previewer tool.
File too large for email?
Email has a 50MB limit. Use USB transfer for larger files, or compress images in your document.
