Open and view e-books online, convert DOCX to EPUB and FB2

Read e-books conveniently

Open and view the uploaded EPUB, FB2, and PDF files online, locally, or on-the-go, no matter what device you are using. Easily navigate through headings, switch to dark theme in low-light environments, print e-books if necessary.

Create interactive e-books

Writing your own book? Make use of multiple styling and formatting tools. Insert a table of contents, refer to images, objects, and charts with a table of figures, explain certain points in footnotes or endnotes, add bookmarks and clickable links to useful resources. Apply watermarks to protect intellectual property. Give your document a professional layout by setting mirror & gutter margins for pages that will be bound together.

Co-author effectively

While creating an e-book, collaborate on a text file with your team. Switch between real-time or paragraph-locking modes, leave comments, track changes, discuss the process in the built-in chat or Telegram. Make audio and video calls via Jitsi.

Export to EPUB, FB2, and PDF

When your work is ready, save the created DOCX file as EPUB or FB2. EPUB adapts to mobile devices, so that you can read comfortably without zooming in and out. FB2 is simple and won't take too much space on your e-book reader. Convert DOCX, EPUB or FB2 to PDF.
