Features

Detailed formatting control for every book you publish.

Koberger is built around the indie publishing workflow: import the manuscript, organize the book, tune the format, preview the result, and export as often as revision requires. Save your choices as a reusable house style, and every book after the first is faster to format.

Author-brand workflow

  • Prepare multiple formats from one project

Differentiators

Built for authors who publish more than once.

A reusable section library

Save any section once and reuse it across every book, images included. Linked sections stay consistent throughout your catalogue, so updating one place updates them all.

Series and box-set tools

Apply one design across a whole series, run a consistency check, build box sets, and find and replace across every book at once. Made for a backlist, not just a single title.

Shareable preview links

Send a private link and your editor or beta reader can read the formatted book right in their browser. No account, no download, nothing to install, and you can revoke it any time.

Beyond formatting

Made for how you actually publish.

Format on any device

Koberger runs in your browser. Nothing to install, and it works the same on Windows, Mac, and Chromebook. No Mac required.

Rich content blocks

Tables, conversations, verse, callouts, buy links, handwritten letters, and ornaments are built in and render in ebook and print.

Watermarked advance copies

Export watermarked eARC EPUBs for reviewers and your launch team, so you can share advance copies with more peace of mind.

Large print editions

Publish a large print edition from the same manuscript, set in 16pt with high legibility letterforms to meet large print standards.
