Book formatting for Windows
Beautiful book formatting on Windows. No Mac required.
The best-known formatting app, Vellum, only runs on a Mac. Koberger gives you the same professional EPUB and print-ready PDF results in your browser, on the Windows PC you already own.
Runs in Chrome, Edge, or Firefox. Nothing to install.
The Windows problem
The best formatting tool doesn’t run on your computer.
If you write on Windows, you have probably hit the same wall: the formatting tool everyone recommends is Mac-only. The usual workarounds are buying a Mac, renting a cloud Mac, or wrestling with Word.
Koberger removes the problem entirely. Because it runs in the browser, your operating system simply does not matter. Windows, Chromebook, an old laptop, a library computer: if it has a modern browser, it can produce a professionally formatted book.

What you get on Windows
Everything you need to publish, in the browser.
EPUB, Print PDF, and DOCX
Export a clean, validated EPUB for ebook stores, an interior PDF sized for KDP paperbacks, and a DOCX if you need one, all from the same project.
See it before you export
Preview the ebook and print layout as you work, so there are no surprises when you upload to Amazon or another retailer.
Front and back matter
Title pages, copyright, dedication, table of contents, and more are built in, with live publishing details you set once.
Any device, always current
Nothing to install and no updates to manage. Start on your PC, pick up on a laptop, and you are always on the latest version.
The finishing touches
Scene-break ornaments, pull quotes, tables, and verse are handled for you, so the small details look intentional without fiddly manual styling.
Windows questions
Formatting on a PC, answered.
01
Does Koberger work on Windows?
Yes. Koberger runs entirely in your web browser, so it works on Windows 10 and 11 exactly the same way it works on a Mac or a Chromebook. There is nothing to download or install.
02
Is Koberger like Vellum for Windows?
It is the closest thing to it. Vellum is a Mac-only app, which leaves Windows authors without an easy way to get that level of finish. Koberger gives you professionally formatted EPUB and print-ready PDF files from your browser on any operating system.
03
Do I need to install anything or buy a Mac?
No. You do not need a Mac, a virtual machine, or a cloud-Mac rental service. You open Koberger in Chrome, Edge, or Firefox on your existing Windows PC and format your book there.
04
Can I make print-ready PDFs for KDP paperbacks on Windows?
Yes. Koberger exports interior print PDFs with the correct trim size, margins, and gutter for Amazon KDP and other print-on-demand services, alongside EPUB for ebooks and DOCX if you need it.
05
How much does it cost?
You can create a free account, import your manuscript, and preview the fully formatted result at no cost. Koberger Pro, which unlocks exporting your publishing files, is 9.99 US dollars per month or 99 US dollars per year.
