From real runs

What you get — and what changes

  • DRM protection Lost

    Encrypted Kindle purchases fail before content is read; this path is for personal documents, sideloaded books, and DRM-free AZW3.

  • Pagination Changed

    The reflowable Kindle layout is newly paginated into fixed PDF pages based on page size, margins, and font settings.

  • KF8 CSS Changed

    AZW3 supports more styling than MOBI, but floats, custom fonts, and device-specific layout may simplify in PDF output.

  • Images Changed

    Images are rendered into the page box and may be downscaled, especially on A4/Letter pages with wide margins.

  • Table of contents Kept

    Readable TOC data becomes PDF bookmarks when our ebook engine can extract landmarks and chapter entries.

  • Cover Kept

    A marked Kindle cover is rendered near the front of the PDF, commonly as page 1.

  • Kindle annotations Lost

    Highlights, notes, sync positions, and library state are not stored in the converted PDF.

Options and when to change them

pageSize
Use A4 or Letter for printing; use smaller page sizes only when the PDF will be read on a device.
margins
Adjust margins when tables or diagrams are clipped, or when printed review copies need note space.
fontSize
Change the base font to trade off accessibility, page count, and line length.

Do it yourself

Calibre ebook-convert

bash

Only DRM-free AZW3 files work. Kindle store purchases may be encrypted even when the file extension is .azw3.

AZW3 to PDF by API or MCP

The HTTP API and the MCP server run the exact engine this page uses (Ebook engine); the response carries the same warnings the web converter shows. Check support first with GET /api/v1/pairs?from=azw3&to=pdf.

curl
curl -X POST https://filetypeconverters.com/api/v1/convert \
  -H "Authorization: Bearer $FTC_API_KEY" \
  -F "file=@input.azw3" -F "from=azw3" -F "to=pdf" \
  --output output.pdf

When this is the wrong conversion

  • Do not upload DRM-protected Kindle purchases; they will not convert.
  • Keep AZW3 when you want adjustable Kindle text, dictionary lookup, and e-reader navigation instead of fixed pages.
  • Use the original DOCX, HTML, or EPUB source if you need publication-quality PDF typography.

AZW3 to PDF questions

Do Kindle personal documents convert?

Yes, if the AZW3 personal document is not encrypted. Sideloaded files and internal Kindle documents are the most reliable inputs.

Can this remove Kindle DRM?

No. DRM-protected AZW3 files fail, and the service does not remove or bypass DRM.

Why did the page count change after I changed margins?

AZW3 is reflowable. Smaller margins or fonts put more words on each PDF page; larger margins or fonts create more pages.
