EPUB Reader & PDF Exporter

Read EPUB ebooks in your browser with chapter navigation, font size control, and reading themes. Export any page to PDF.

About EPUB Reader & PDF Exporter

EPUB Reader & PDF Exporter lets you open any EPUB ebook file directly in your browser without installing dedicated software. Drop or select your .epub file and the reader renders the book's content inside a paginated reading pane powered by epub.js. The table of contents sidebar lists all chapters so you can jump to any section with a single click. Navigate page by page using the Prev and Next buttons or click any chapter title to jump directly. Three reading themes are included — White for standard reading, Sepia for a warm paper-like feel that reduces eye strain, and Dark for low-light environments. A font-size slider adjusts text from 14px to 28px to suit your preference. When you want a portable copy of the current page, the Export PDF button renders it to a standard A4 PDF using html2pdf.js.

Examples

Open a Project Gutenberg book

Input: alice-in-wonderland.epub

Output: Renders the full novel with chapter ToC and Prev/Next navigation.

Tips

  • Use the Sepia theme for long reading sessions — its warm tone is gentlest on the eyes.
  • If the table of contents is empty, the EPUB lacks navigation metadata; use Prev/Next instead.
  • For DRM-free books from Project Gutenberg, the reader works flawlessly.
  • Increase font size for accessibility — the slider goes up to 28px which suits readers with vision needs.
  • To export the full book as PDF, use a dedicated EPUB-to-PDF converter — this tool exports one page at a time.

Frequently Asked Questions

Is my ebook uploaded to your server?▾
No. epub.js reads the file directly from your device's memory using the FileReader API. Nothing is uploaded.
Which EPUB versions are supported?▾
epub.js supports EPUB 2 and EPUB 3 files. Most ebooks downloaded from standard sources use one of these formats.
Why does the PDF export only capture one page?▾
The Export PDF feature captures the currently visible rendered page. EPUB reflowable content is paginated dynamically, so exporting the full book would require iterating through every page, which this tool does not automate.
Can I export the whole book as PDF?▾
Not automatically. Use the Export PDF button on each chapter individually, or consider a dedicated EPUB-to-PDF conversion tool for full-book exports.
The table of contents is empty — why?▾
Some EPUB files do not include a standard NCX or navigation document. In this case epub.js cannot extract the chapter list, and you can only navigate with Prev / Next.
Does the font size change persist between sessions?▾
No. Settings reset when you close or reload the page. The tool is stateless and stores nothing.
Are there any DRM-protected EPUBs that won't work?▾
Yes. EPUBs with Adobe DRM, Apple FairPlay, or other digital rights management cannot be opened by epub.js. The tool works only with DRM-free EPUB files.
Can I bookmark or save my reading position?▾
No. The reader is stateless — closing or reloading the page resets your position. Use the table of contents to jump back to where you left off.
