maratoolHow to convert EPUB to PDF online
Upload an EPUB, preview its chapters, and download as PDF, HTML, or plain text — all without sending your file to a server.
EPUB is the standard format for e-books from publishers, libraries, and self-publishing platforms. Sometimes you need a PDF for printing, an HTML archive, or plain text for search and analysis. The EPUB Converter handles all three output formats in your browser.
How it works
- Upload — drop an unencrypted .epub file. EPUB is a ZIP archive; the tool unpacks it locally with JSZip.
- Parse — reads the OPF manifest and spine to determine chapter order, then loads the table of contents from the nav document (EPUB 3) or NCX (EPUB 2).
- Preview — click any chapter in the sidebar to render its XHTML content with images and styles resolved from the archive.
- Download — choose PDF, HTML, or TXT and save the converted file.
Output formats
PDF — chapters are combined into a single document and rendered with html2pdf.js. Complex layouts and large image-heavy books may take longer; very large files are limited by browser memory.
HTML — exports one standalone .html file with all chapters in reading order. Useful for archiving or opening in any browser without an e-reader app.
Plain text — strips HTML tags and outputs chapter headings plus body text. Good for word counts, grep, or feeding into other tools.
Limitations
- DRM — copy-protected EPUBs (Adobe DRM, Kindle formats) cannot be opened. Only standard, unencrypted EPUB files work.
- PDF fidelity — browser PDF rendering preserves text and basic layout but may not match a dedicated desktop converter for complex typography.
- File size — large illustrated books consume more RAM during conversion. If the browser tab crashes, try HTML or TXT instead of PDF.
