AZW3 to PDF
Turn Kindle ebook (AZW3) files into PDF document files on your own Mac, Windows or Linux computer. Asteria is free, works offline, and never uploads your files.
How to do it
- Download Asteria and open it. It's free and needs no account.
- Drop your AZW3 files onto its window, or press ⌘O (Ctrl O on Windows) to choose them. Drop as many as you like.
- Type convert ebook to pdfand press Enter. PDF from an e-book.
- The first time, Asteria asks to download Calibre, a free add-on from Kovid Goyal, under the GPL-3.0-only license. It shows the download size before you say yes, and needs no administrator password.
- Press ⌘↵ (Ctrl ↵ on Windows) to save. The PDF files appear next to the originals, which stay exactly as they were.
What it needs
AZW3 to PDF uses Calibre, a free program for ebooks. Asteria doesn't bundle it. The first time you need it, Asteria offers to download it, checks the download against a pinned checksum, and keeps it in its own folder, where Settings can remove it again. If Calibre is already on your computer, Asteria uses that copy.
How it was tested
A real AZW3 file was converted on Linux, and the PDF that came out was opened and checked with poppler pdfinfo to make sure it is what it says it is.
