eBook to PDF Converter

How Do You Convert an eBook to PDF?

You convert an e-book to PDF by adding the file to QuickCatPDF's eBook to PDF converter, choosing a page size, and clicking Convert to PDF. The book comes back as a PDF with real, selectable text, its pictures and styles, a bookmark for each chapter and page numbers, ready to read on any device or print.

One page handles every common e-book format: EPUB, MOBI, AZW3 and AZW, PRC, FB2, PDB, CBR and CBZ comics, and DjVu scans. It's free, needs no sign-up and adds no watermark.

How to Convert an eBook to PDF With QuickCatPDF

Converting a book takes four steps.

1. Click Select e-book files or drop your files on the page (up to 10 files).
2. Check the settings for each kind of file: Page size and Text size for books, Page size for comics, Resolution for DjVu.
3. For several files, choose Separate PDFs or One combined PDF.
4. Click Convert to PDF, then download each PDF, the ZIP or the combined PDF.

Settings appear only for the kinds of file in your list, so a single EPUB shows the book settings and nothing else.

Which eBook Formats Can You Convert?

Each family of formats is converted in the way that suits it.

Dedicated pages cover each one in more detail: EPUB to PDF, MOBI to PDF, AZW3 to PDF, CBR to PDF and DjVu to PDF.

Why Does a PDF of an eBook Need a Page Size?

E-books have no fixed pages. Their text reflows to fit whatever screen opens them, while a PDF has pages of a set size, so the converter has to lay the book out like a printer would. The Page size setting decides the shape of those pages.

A5 (148 × 210 mm) is the default because it matches a typical paperback and reads well on tablets and phones. Choose 6 × 9 in for a trade-paperback look, or A4 and Letter for printing on office paper. Text size sets how large the text is on the page, so a larger size gives more pages.

In our test, a three-chapter EPUB with a cover and a picture became 9 A5 pages with the default settings and 6 A4 pages with large text and no cover.

What Does the PDF Keep From the Book?

Text e-books keep the parts that matter for reading:

• the text as real text, so you can search it, select it and copy it;
• the book's own fonts, styles and pictures;
• a bookmark for each chapter, taken from the book's contents;
• links between chapters and to footnotes, as working links;
• the cover as the first page, without a page number;
• the book's title in the PDF's document details.

Each chapter starts on a new page, and headings are kept with the text that follows them. Scripts, forms and anything else that could run inside a book are removed before the layout starts.

Is It Safe to Upload My Books?

Yes. Books, comics and DjVu files are converted on our own server, because a browser can't save a laid-out book as a PDF file by itself. Files travel over HTTPS and are converted in a sandboxed service with no internet access. The original is deleted when the conversion ends and the PDF as soon as your browser downloads it, and nothing is kept more than 1 hour.

For a single EPUB, MOBI, AZW3, FB2 or PDB book there's also Save as PDF on this device. It lays the book out in your own browser and opens the print window, where you choose Save as PDF, so the book is never uploaded. With that option, page numbers, headers and bookmarks depend on your browser's print settings rather than ours.

What Can't Be Converted?

Books with DRM can't be converted. Most books bought from the big e-book stores are protected this way, and the tool tells you when a file has DRM instead of producing an empty PDF.

KFX and LIT files and eReader-style PDB books aren't supported either. Fixed-layout EPUBs, such as picture books, are converted as flowing text, so their page design isn't kept exactly.
