About the MOBI to PDF
MOBI is the e-book format made for older Kindles, and many free books from libraries and Project Gutenberg come in it. A PDF is easier to read on a computer, print, or open on any device without a reading app. This converter reads a DRM-free MOBI or AZW book in your browser and lays out its text, headings, lists and pictures on A4 or Letter pages, with page numbers if you want them. Chapters start on new pages where the book marks them. Nothing is uploaded, and books with DRM are refused with a clear message instead of failing silently.

Why convert a MOBI to PDF
A MOBI file needs a Kindle or a reading app. A PDF opens everywhere: on a laptop browser, on a phone, in a print shop, or on an e-reader that prefers PDF. It is also the simplest way to print a short book or to share a free public-domain title with someone who has no Kindle app.
What gets converted
The converter reads the compressed text inside the book, then the headings, paragraphs, lists, bold and italic text, and pictures. Page breaks that the book marks between chapters become real page breaks in the PDF. The first heading of each chapter keeps its size, so the structure is easy to follow.
- Headings, paragraphs, bold and italic
- Bulleted and numbered lists
- JPG and PNG pictures
- Links that point to a web address
Books that cannot be converted
If a book has DRM, the text is encrypted and cannot be read here; the tool says so. The same goes for a few rare compression formats and for KF8 books. For those, look for a DRM-free copy from the publisher, a library or a public-domain site, and try again.
Getting a nice PDF
Choose A4 outside the United States and Letter inside it. Normal text size works for reading on a screen, and Large is easier on tablets or for printing. Turn page numbers on if you plan to print, so you can keep the pages in order.
Phone and computer
On a phone, pick the book from your files app and save the PDF afterwards. Long books may take a moment, so keep the page open. On a computer you can drop the file straight on the page. The PDF is built on your device, so it also works over a slow connection once the page has loaded.
Good to know
MOBI books carry their chapters in one long document. If a book has no page break marks, the PDF simply flows from chapter to chapter. Tables inside MOBI books are usually flattened by the Kindle format itself, so they appear as text lines. Always glance through the result before you print. A PDF is easy to share, but e-readers use other formats too. Use MOBI to EPUB for a more common e-book format, EPUB to PDF when that is the file you have, and PDF to EPUB to return a document to a reader.

Frequently asked questions
Can it open any Kindle book?
Only DRM-free books in the classic MOBI layout. Books bought from the Kindle store are usually protected with DRM and cannot be read by any converter. KF8 (AZW3) books use a newer layout that this tool does not read yet.
Does it keep the pictures?
Pictures saved as JPG or PNG inside the book are placed in the PDF. Other picture types, such as GIF, are skipped.
Will the PDF look like the Kindle page?
No. The PDF has its own clean layout with a readable font. Fonts, colours and exact page breaks of the original are not copied.
Why do some characters show as question marks?
The PDF font covers Latin alphabets. Greek, Cyrillic, Asian scripts and emoji are not supported yet, and the result page lists the characters that were replaced.
How long does a big book take?
A 300-page novel usually converts in a few seconds. Books with many large pictures take longer, because the pictures are embedded.
Is my book uploaded?
No. The conversion runs on your own device and nothing is sent anywhere.
