or click to browse - works for EPUB 2 and EPUB 3 ebooks

EPUB (Electronic Publication) is the open standard ebook format maintained by the W3C and used by virtually every publisher and ebook store except Amazon. Apple Books, Kobo, Google Play Books, and most library lending platforms all distribute .epub files. A reliable EPUB viewer lets you read these books on any device with a browser - no Kindle, no Kobo, no app installation.
Technically, an .epub file is a ZIP archive containing XHTML chapters, images, stylesheets, and metadata. That structure is exactly what this viewer unpacks in your browser. If you ever want to inspect the raw files inside an EPUB, you can open it in our Archive Viewer - rename it to .zip or open it directly and browse the chapter files yourself.
EPUB 2 (2007) established the core format: reflowable XHTML content with an NCX table of contents. EPUB 3 (2011, updated since) replaced the NCX with an HTML5 navigation document and added support for audio, video, MathML, and fixed layouts. This viewer handles both - it reads the EPUB 3 navigation document when present and falls back to the NCX for older books.
The key difference is reflow. EPUB text adapts to your screen size and font preference, which makes it far more comfortable on phones and tablets. PDF preserves a fixed page layout, which is better when exact formatting matters - forms, contracts, and academic papers. For plain text notes, our TXT Viewer and Markdown Viewer cover the lightweight formats, while the DOCX Viewer handles Word documents.
Upload your .epub file by dragging it onto the upload area or clicking to browse. The book is unpacked and rendered directly in your browser - no software, no signup, no upload to any server. The table of contents appears on the left and you can read chapter by chapter immediately.
You do not need a Kindle, Kobo, or any e-reader app. Upload the .epub here and read it in your browser on Windows, Mac, Linux, Chromebooks, and mobile. Chapters, images, and the table of contents all work just like in a dedicated reader. Note that Kindle uses its own formats (AZW3, KFX) - those need conversion before they can be read as EPUB.
EPUB (Electronic Publication) is the open standard ebook format used by virtually every publisher and ebook store except Amazon. Technically, an .epub is a ZIP archive containing XHTML chapters, images, styles, and metadata - you can even browse the raw files in our Archive Viewer. EPUB 3, the current version, adds audio, video, and improved navigation support.
Yes. The viewer reads the EPUB 3 navigation document when present and automatically falls back to the EPUB 2 NCX table of contents for older books. Chapter content, embedded images, and metadata work for both versions.
No. Books protected with Adobe DRM or other encryption schemes cannot be opened by any standard EPUB reader, including this one. DRM-free books - the kind sold by most independent publishers and provided by Project Gutenberg - open perfectly.
EPUB text reflows to fit any screen size, which makes it ideal for phones and e-readers. PDF preserves a fixed page layout, which is better for documents where exact formatting matters. For reading novels and most non-fiction, EPUB is the more comfortable format. To view fixed-layout documents, use our PDF Viewer.
