EPUB to PDF

Convert EPUB ebooks to PDF. Server-side Calibre engine. Free, no signup, no watermark. Conversion can take 30-90 seconds for large books.

Your EPUB uploads over HTTPS, gets converted by Calibre, then deleted immediately. Nothing logged or stored.

Convert EPUB ebooks to PDF for printing or PDF readers. Calibre engine preserves chapters and TOC.

EPUB to PDF is the conversion you need when an ebook needs to leave its reader and become a printable, shareable, archivable document. EPUB is brilliant for reflowable reading on Kindle, Kobo, or Apple Books — but PDF is the lingua franca for printing, university submissions, legal archives, and any system that demands fixed-page format.

Pick Rack's EPUB to PDF tool uses [Calibre](https://calibre-ebook.com/), the gold-standard open-source ebook converter maintained for over 15 years. Calibre handles EPUB 2 and EPUB 3, preserves your table of contents as PDF bookmarks, embeds chapter structure, and applies clean typography defaults.

Free, no signup, no watermark. Files up to 50MB are supported. Conversion typically takes 30-90 seconds for novel-length books due to Calibre's full text-flow analysis.

Key features

  • Calibre conversion engine — The same engine used by millions of Kindle users to convert their personal libraries. Robust, predictable, well-tested across thousands of EPUB variants.
  • Table of contents as PDF bookmarks — Your EPUB's chapter structure becomes navigable bookmarks in the PDF — clickable in any modern PDF viewer.
  • Hyperlinks preserved — Internal cross-references (footnotes, chapter links) and external URLs remain clickable in the converted PDF.
  • Cover image included — If your EPUB has a cover image, it appears as the first page of the PDF.
  • No watermark, no signup — Output PDF has zero added marks. Most online EPUB→PDF tools watermark heavily — Pickrack is genuinely free.

How to use

  1. Step 1: Upload your EPUB — Drop a single .epub file (up to 50MB) into the dropzone.
  2. Step 2: Click Convert to PDF — Calibre processes the ebook server-side. Wait 30-90 seconds — Calibre does full text-flow analysis to produce clean output.
  3. Step 3: Download the PDF — A green download button appears. The PDF includes cover, table of contents (as bookmarks), and all chapters.

When to use

  • Print a Kindle book by converting EPUB → PDF first (most printers don't accept EPUB)
  • Submit an ebook as an academic reference when the journal demands PDF format
  • Archive personal library in PDF format for long-term cross-platform access
  • Annotate an ebook in a PDF reader (GoodReader, PDF Expert) that has better markup tools than Kindle
  • Send an EPUB to someone without an ebook reader — they can read the PDF in any browser
  • Convert public-domain Project Gutenberg EPUBs for offline PDF distribution

Frequently asked questions

What's the difference between EPUB and PDF?

EPUB is reflowable — text wraps to fit any screen size, font size is adjustable, and the layout is dynamic. PDF is fixed-page — each page is exactly the same on every device, like a printed page. EPUB is better for reading on phones; PDF is better for printing, archiving, and exact-layout sharing.

Does this preserve the table of contents?

Yes. Calibre converts the EPUB's nav.xhtml or toc.ncx into PDF bookmarks. Open the PDF in Adobe Reader, Preview, or Foxit and click the bookmarks icon to see the navigable chapter list.

Will the output PDF have the EPUB's cover image?

Yes, if your EPUB includes a cover image (most do). It becomes page 1 of the PDF.

Can I convert DRM-protected EPUBs (Kindle, Apple Books, Adobe DE)?

No. DRM-protected ebooks cannot be converted by any tool — including this one — without first removing DRM, which is illegal in many jurisdictions. Only convert EPUBs you own DRM-free (Project Gutenberg, Standard Ebooks, books from DRM-free publishers like O'Reilly, No Starch Press, Pragmatic Bookshelf).

Why does conversion take 30-90 seconds?

Calibre does full text-flow analysis: cleaning up CSS, normalizing font sizes, generating page breaks, embedding fonts, and rendering each page. The result is a much cleaner PDF than a faster "dump-to-PDF" converter would produce.

What about EPUB 3 features like fixed-layout, multimedia, MathML?

Fixed-layout EPUB 3 (used for comics, picture books) converts but layout fidelity depends on the source. Multimedia (audio, video) is not embedded in the PDF. MathML equations render as text or images depending on Calibre's interpretation.

Can I customize page size, margins, or font?

v1 uses Calibre defaults (Letter size, 1-inch margins, 12pt serif). Custom page sizes (A4, A5, Kindle-sized) and margin controls are on the roadmap. For full control, install Calibre desktop locally and use ebook-convert with custom CLI flags.

What's the file size limit?

50MB EPUB. Most novels are 1-5MB; technical books with images are 10-30MB; image-heavy comic books can exceed 50MB and would need to be split first.
