Technical Overview: RTF to AZW3

Understanding Kindle Format 8 features and how RTF formatting translates to e-readers.

Why AZW3 (KF8) Over Legacy AZW/MOBI

Kindle Format 8 (AZW3) replaced legacy MOBI/AZW, introducing full HTML5 and CSS3 support. AZW3 allows custom font selections, drop caps, justified margins, and richer paragraph styling. Output generated by ScanPDF is strictly genuine KF8/AZW3, never renamed legacy PalmDOC files.

Formatting Preservation Details

Standard RTF text elements—such as bold, italic, underline, paragraph spacing, and basic bullet points—are accurately translated into HTML/CSS inside the AZW3 archive. Complex word processor drawing canvas shapes, OLE embedded objects, and macro fields from RTF are omitted to comply with e-book rendering standards.

Frequently Asked Questions

Which Kindle devices support AZW3 files?

AZW3 is natively supported by Amazon Kindle Paperwhite, Kindle Oasis, Kindle Scribe, Kindle Basic (5th Gen and newer), and the Kindle apps for PC, Mac, Android, and iOS.

How do I transfer AZW3 files to my physical Kindle?

Connect your Kindle to your computer using a USB cable, navigate to the "documents" folder on the Kindle drive, and drag and drop your downloaded .azw3 file. It will appear immediately in your Kindle library.

Does ScanPDF retain any part of my RTF manuscript?

No. ScanPDF practices zero persistence. Your RTF document and the generated AZW3 are held only in isolated temporary storage during processing and purged as soon as you receive the download.
