How to Convert EPUB to PDF

The core trade-off: EPUB text reflows to fit any screen. PDF locks layout to fixed pages. Converting makes sense when you need to print, share with someone who has no EPUB reader, or submit to a system that only accepts PDF. Here's what each method produces and what you give up.

Method 1: Epublys

1. Open the EPUB to PDF converter
2. Upload your EPUB (up to 10MB free)
3. Click Convert to PDF and download — no watermarks, no account

Output is A4 by default. Embedded fonts are used if present; otherwise falls back to a clean serif. Images are included at original resolution; SVGs are rasterised at 150dpi. Chapter navigation is converted to PDF bookmarks. Conversion runs in-memory on Cloudflare Workers — your file is never written to disk and is gone the moment the response returns.

Before converting: validate your EPUB to catch broken internal links that would produce blank pages, and use the metadata editor to set the correct title — it ends up in the PDF's document properties.

Method 2: Calibre (More Output Control)

Calibre lets you set page dimensions (A4, Letter, or custom), margins, font size, and override stylesheets. Use this when the default output doesn't match what you need.

1. Add your EPUB to Calibre and click Convert books
2. Set output format to PDF
3. Under "PDF Output": configure page size, margins, font
4. Click OK — PDF conversion is noticeably slower than other formats in Calibre

Calibre uses its own rendering engine, not a browser engine. Very complex CSS may not render perfectly. For typographic precision, Pandoc with a LaTeX backend produces cleaner output.

Method 3: Pandoc

pandoc input.epub -o output.pdf
# Custom page size:
pandoc input.epub -o output.pdf -V geometry:a4paper
# Custom font (requires XeLaTeX):
pandoc input.epub -o output.pdf --pdf-engine=xelatex -V mainfont="Georgia"

Pandoc re-typesets through LaTeX — it strips EPUB styling and applies its own layout rules. The output is clean and professionally typeset but looks different from the source EPUB's design. Best for academic or technical documents where presentation matters more than matching the original.

What Survives the Conversion

Text, headings, tables, and inline images come through cleanly. What changes:

• Multi-column layouts collapse to single-column
• Fixed-layout EPUBs (manga, magazines) are rendered page-by-page as images — quality depends on original resolution
• EPUB 3 JavaScript interactivity is dropped entirely
• Precise CSS positioning is approximated by the converter's layout engine
