Frequently Asked Questions

What is an EPUB file?

EPUB (Electronic Publication) is a widely-used open standard for digital books and publications. It’s supported by most e-readers and reading applications, offering reflowable text that adapts to different screen sizes and reading preferences.

Which EPUB formats does this tool support?

Our EPUB viewer supports EPUB 2 and EPUB 3 formats, including books with embedded images, tables, and basic multimedia content. The tool handles most standard EPUB files created by popular publishing platforms and conversion tools.

Is my uploaded file stored on your servers?

No, your EPUB files are processed entirely in your browser using client-side JavaScript. Files are never uploaded to our servers, ensuring complete privacy and security of your personal reading materials.

Can I use this tool offline?

Once the page is loaded, you can read your uploaded EPUB files without an internet connection. However, you’ll need internet access initially to load the tool and whenever you want to upload new files.

How do I navigate between chapters?

Use the Table of Contents panel on the left side to jump directly to any chapter. You can also use the Previous/Next buttons at the bottom of the reading area or click on chapter titles in the navigation panel.

Can I search for specific text within the book?

Yes, use the search box in the text controls area to find specific words or phrases throughout the entire book. Search results will be highlighted in the text, and you can navigate between matches.

Are my reading preferences saved?

Your reading preferences including font size, font family, and theme selection are automatically saved in your browser’s local storage. Bookmarks and reading progress are also preserved for future sessions.

What should I do if my EPUB file won’t open?

Ensure your file has the .epub extension and isn’t corrupted. Some DRM-protected EPUB files may not open in browser-based readers. Try opening the file in a dedicated e-reader application first to verify it’s working correctly.
