How Do You Convert a PDF to AZW3?
You convert a PDF to AZW3 by adding it to QuickCatPDF's PDF to AZW3 converter and clicking Convert to AZW3. The text is rebuilt as a modern Kindle (KF8) e-book: reflowable text with styled headings, chapters with the Kindle's own table of contents, pictures and a cover.
The PDF is converted in your browser and never uploaded. It's free, with no sign-up and no watermark.
How to Convert PDF to AZW3 With QuickCatPDF
Converting to AZW3 takes four steps.
- Click Select PDF files or drop your PDFs on the page (up to 20).
- Choose where a new chapter starts, and whether to make a cover from page 1.
- Type a range in Pages if you only need part of the PDF.
- Click Convert to AZW3, then download the Kindle book.
What Is AZW3?
AZW3, also called KF8 (Kindle Format 8), is the Kindle e-book format used since 2011. Unlike the older MOBI, it supports style sheets, so headings, tables, pictures and spacing look closer to the original. The chapters are listed in the book's built-in table of contents, and the text reflows to the screen, so you can change the font size.
Kindle e-readers from 2011 onwards, including every Paperwhite, Oasis and Scribe, read AZW3. For older Kindles, use PDF to MOBI.
How Good Is the Result?
QuickCatPDF rebuilds the PDF's headings, paragraphs, lists, tables and pictures, joins lines broken at the end of each PDF line, and leaves out page numbers and running headers. Each chapter becomes its own section, so the Kindle can jump to it.
In our test, a 4-page report became a 137 KB AZW3 in under a second. An independent Kindle-format unpacker read it as a KF8 book with every chapter, and the eBook reader used on this site's AZW3 to PDF tool showed all its text.
PDFs that are mostly running text work best: novels, reports, manuals and papers. Scanned PDFs are read with text recognition first; choose the languages under Scanned pages (OCR).
How Do I Put the Book on My Kindle?
Connect the Kindle with a USB cable and copy the AZW3 into its documents folder; it appears in the library when you unplug it. The Send to Kindle service doesn't accept AZW3, so for that use PDF to EPUB.
