The toolkit

A focused formatter for book interiors.

Professional defaults, meaningful controls, and a clear handoff to your final review.

Book-ready page setup

Choose core trim sizes for free, or unlock 5.25 × 8, 5.5 × 8.5, 6.14 × 9.21, 7 × 10, and 8 × 10 in Pro. Print mode adds mirrored margins.

Typography that stays consistent

Normalize body styles, line spacing, paragraph spacing, indentation, and chapter headings without editing every paragraph by hand. Pro adds more font families, sizes, and spacing options.

Front matter and table of contents

Add title, copyright, dedication, and a Word-compatible dynamic TOC when your project needs them.

Quality checks

Scan embedded images for low DPI and show warnings alongside the output so you know what deserves another look.

Cover page generation

Pro users can upload PNG, JPG, or WEBP artwork and export a cropped 300 DPI PDF cover page matched to their trim size.

Private project storage

Each user and project receives an isolated storage path. Downloads are authorized on the server, not by a hidden browser button.
