Convert EPUB to PDF: read anywhere, fully private

Turn an EPUB ebook into a PDF you can print, annotate, or open on any device. pdfcosmos unpacks and renders it entirely in your browser, so your library never leaves your device.

Chapters are rendered in reading order as real, selectable text. The layout reflows into a clean theme (author CSS isn't reproduced, images become alt text, nothing is fetched), so it's ideal for text-first books. DRM-protected files can't be converted.

  • Real selectable text

    Copy, search, and highlight, not an image of the page.

  • Reading order preserved

    Chapters follow the ebook's spine order.

  • Private by design

    Unpacked and rendered in your browser. Nothing is uploaded.

  • Batch to one ZIP

    Convert up to 30 ebooks at once. Several download together as a ZIP.

How to convert EPUB to PDF

  1. Add your EPUB files

    Drop one (or up to 30) .epub files into the upload area.

  2. Pick page size

    Choose A4 or US Letter. Chapters are laid out with real, selectable text.

  3. Convert & download

    Click “Convert to PDF”. Each ebook is rendered in your browser (a ZIP for several).

Frequently asked questions

Are my EPUB files uploaded to a server?
No. The ebook is unpacked and rendered entirely in your browser. It never leaves your device. You can confirm it in your browser's Network tab: no data is sent.
Is the text selectable in the PDF?
Yes. Chapters are rendered as real, selectable text (not images), in reading order, using clean built-in fonts (Latin scripts).
What about the ebook's images and styling?
The text reflows into a clean layout. The author's CSS isn't reproduced, and embedded images appear as their alt text (to keep everything local, nothing is fetched). It's best for text-first books.
Does it work on DRM-protected ebooks?
No. DRM-protected EPUBs (e.g. many store purchases) are encrypted and can't be converted. Use a DRM-free EPUB.
Can I convert several ebooks at once?
Yes. Add up to 30 .epub files. One downloads as a PDF, and two or more download together as a single ZIP.
Is EPUB to PDF free?
Yes, it's completely free to use, with no sign-up and nothing to install.
