Convert AZW3 to PDF.
Turn a DRM-free AZW3 (Kindle KF8) ebook into a PDF that opens on any device and prints cleanly.
What AZW3 is
AZW3, also called KF8, is the Kindle format that replaced MOBI. It supports richer layout and styling. Self-published authors, Calibre users and DRM-free stores often produce it.
Why convert to PDF
A PDF lets you read the book on a computer without Kindle software, share a chapter for study, or print it. Fixed pages are ideal for printing and annotation.
Prefer reflowable text?
If you want to keep the book reflowable for another ereader, convert AZW3 to EPUB instead, which most non-Kindle readers use.

AZW3 to PDF
This re-flows the book into PDF, carrying chapters, the table of contents and images. Reflowable ebook formats adapt to the reader's screen and font size. Heavy fixed layouts (comics, textbooks) convert less cleanly.
Common questions
Is it free?+
Yes. Convert AZW3 to PDF free. No signup and no watermark. Free covers 10 server conversions a day, up to 100 MB a file. Pro removes the daily limit and raises the file limit to 2 GB.
Is my file private?+
Your file is uploaded to a private bucket, converted on our own engine, and auto-deleted after 1 hour. It is never sent to a third-party converter.
Does it work on Kindle Store purchases?+
Only on DRM-free files. Most Kindle Store books are protected by DRM, which cannot be converted by FileWhirl or any legitimate converter.
Is the formatting kept?+
Chapters, headings, images and emphasis carry across. The text is set onto fixed pages, so line and page breaks differ from what a Kindle shows.
