Chapters become PDF bookmarks
In our test the 12 chapters and two sub-entries of the book's contents list became 15 bookmarks, so a PDF reader lets you jump from chapter to chapter.
AZW3 to PDF Converter
You get a PDF of your AZW3 book: fixed pages you can print, send or open on any device, with no Kindle app needed.
To convert azw3 to pdf, add the AZW3 file, keep PDF as the output format and download the result. The book changes from reflowable text into fixed pages, so it no longer adapts to the screen. In our test a 42 KB book with 12 chapters became a 17-page PDF of 164 KB with 15 bookmarks. A book locked with DRM, as many Kindle Store titles are, cannot be converted.
Transfers use HTTPS, and files converted on the free tier are deleted after 24 hours, so the result is not a long-term archive. Quality depends on the source file, so open the PDF file once before you share it.

AZW3 (Kindle Format 8)
Amazon's Kindle Format 8, introduced in late 2011 with the Kindle Fire. It holds reflowable HTML and CSS, supporting a subset of HTML5 and CSS3, inside a container that also carries a backwards-compatible MOBI layer. It is proprietary and can be locked with DRM. Amazon's newer KFX format has since replaced it for many Kindle Store books.

PDF (Portable Document Format)
The fixed-page format for printing, sharing and archiving. A PDF keeps every line on the page where it was placed, embeds its fonts and opens on almost any computer, phone, tablet or browser.

Why use indox to convert AZW3 to PDF?
Images and tables come along
The cover, a PNG figure with transparency, a JPEG figure and a bordered table all appeared in the PDF, and the table kept its borders.
Fonts are embedded
Every font in our test PDF was embedded as a subset, so the pages look the same on a computer that lacks those fonts.
A contents page is added at the end
In our test a Table of Contents page was appended as the last page of the PDF, after the book's own pages.
No account in our test
We converted anonymously. We saw no sign-in, quota or payment prompt during our four test conversions.
What happens to your book
Stays
- The text and the order of the chapters
- Your original AZW3, which is not touched
- The cover, figures and table, which appeared in our test PDF
- Table borders, which were kept in our test
Changes
- Reflowable text becomes fixed pages that no longer adapt to the screen
- Page size and margins come from Calibre's defaults, 612 by 792 points in our test
- A Table of Contents page is added at the end
- DRM protection blocks the conversion altogether
Which way should you convert?
| If you | Use | Because |
|---|---|---|
| Need a specific page size, margins or page numbers | Calibre on your computer | Its ebook-convert tool exposes paper size, margins and page numbers, while indox uses the defaults |
| Have one or two DRM-free books and no software | This page | You add the file in the browser and install nothing |
| Bought the book with DRM | Keep it in the Kindle app | Converters, including this one, cannot open DRM-locked files |
| Want a book that still reflows on other e-readers | AZW3 to EPUB | EPUB is an open format that most e-readers open |
How do I convert AZW3 to PDF online?
- 1
Add your AZW3 file
Drop the AZW3 file on the box or choose it from your device. Use a copy without DRM, such as a book you wrote, a public-domain title or a file from your own Calibre library.
- 2
Confirm PDF, then start the conversion
Check that PDF is the output format, then start the conversion and wait for it to finish. In our test a 42 KB book took 9.9 seconds from the click to Completed, and a 14 KB Persian book took 7.4 seconds.
- 3
Download the PDF and page through it
Save the PDF and look at the cover, a page with a figure, a table and the bookmarks panel before you print or send it. Keep the AZW3 as your master copy.
What do I get from indox's AZW3 to PDF converter?
You hand over an AZW3 file and take away a PDF with fixed pages, embedded fonts and chapter bookmarks. Nothing is installed on your computer. The page says up front that DRM-protected books cannot be converted and that the layout comes from Calibre's defaults.
- A PDF with your chapters as bookmarks
- Nothing to install on Windows, Mac or a phone
- Results measured on a test book we made
- A plain statement of what changes and what fails
What are the limits for AZW3 to PDF?
Size
The upload box shows the live size limit before you add a file. Signing in raises it; a paid plan does not change it.
Formats
AZW3 in, PDF out. Pick another output on the converter if you need a different format.
Privacy
Files are encrypted in transit over HTTPS and processed on indox infrastructure.
Deletion
Free-tier files are kept for 24 hours after the job finishes, then deleted automatically.
Limits worth knowing
- A DRM-protected AZW3 cannot be converted. indox does not remove DRM, and an encrypted file fails. We did not test a DRM file, so this follows from how the converter is built. Many Kindle Store purchases carry DRM.
- There are no options. Page size, margins, fonts and page numbers come from Calibre's defaults, and you cannot change them here.
- Persian text is shaped and readable, but not polished. In our test the letters joined correctly and the word order was right, yet paragraphs were left-aligned and the final period of each paragraph was drawn at the first-word side of the last line.
- The layout is automatic. A cover can be stretched and a caption can sit apart from its figure, as it did in our test. Look through the PDF before you print it.
- We tested one text book with images and one Persian book. We have not tested comics, image-only books or very large files, so we cannot say how those come out.
When the result is not what you expected
| What you see | Why | What to do |
|---|---|---|
| The conversion fails | The file may be protected with DRM or damaged, and indox does not remove DRM | Use a DRM-free copy, such as a book you wrote or a public-domain file |
| The cover looks stretched | The converter draws the cover across the whole first page | Accept it for reading, or use Calibre on your computer where you can control the layout |
| A caption sits on a different page | Fixed pages break wherever the text runs out | Check the pages you plan to print and edit the source book if it matters |
| Persian paragraphs lean left and the final period looks misplaced | The converter does not right-align the text or place the full stop correctly | Use the PDF for reading, and check the last line of each paragraph |
| You want to keep the book reflowable | A PDF is always fixed | Convert to AZW3 to EPUB instead |

AZW3 to PDF FAQs
How do I convert AZW3 to PDF?
Add the AZW3 file to the converter in your browser, keep PDF as the output and download the result. Nothing is installed. The file must be free of DRM.
Does the PDF keep the formatting?
Mostly, with changes. In our test the chapters, the images, the table borders and the fonts came through, and the chapters became bookmarks. The text is set into fixed US Letter pages, the cover was stretched and one caption moved to its own page.
Can I convert a DRM-protected AZW3 file?
No. A file locked with DRM cannot be read by the converter, and indox does not remove DRM. If you own the book, keep reading it in the Kindle app or device that holds its licence.
Is it free, and is there a limit?
During our test we used the page anonymously for four conversions and saw no sign-in, quota or payment prompt. We did not test beyond that, and limits can change, so the page itself is the final word.
How long does the conversion take?
In our test a 42 KB book with 12 chapters took 9.9 seconds from the click to Completed. A 14 KB Persian book took 7.4 seconds. A larger book will take longer.
How do I open an AZW3 file?
Kindle devices and Kindle apps open AZW3 files, and so does the free calibre ebook manager. Most other readers do not, which is the usual reason to convert it to PDF or EPUB.
What is the difference between AZW3 and EPUB?
AZW3, also called KF8, is Amazon's proprietary format from 2011 and can carry DRM. EPUB is an open standard that most e-readers except Kindle open. For a PDF of an EPUB book, use [EPUB to PDF](/convert/epub-to-pdf).
Does it work with Persian or Arabic text?
The letters are shaped and joined correctly and the word order is right. In our test the paragraphs were left-aligned and the final period of each paragraph appeared at the wrong end of the last line, so check the result before you print it.
Why does a page look nearly empty?
In our test the first page held only the cover image, and one page held only a seven-word figure caption. We saw no blank pages. We have not tested comics or image-only books.
