Features

Professional interior formatting for self-publishers

DOCX Upload with Images

Upload your Word manuscript directly. Images are extracted and placed in the PDF at their original positions. No copy-paste needed.

Professional Book Fonts

Crimson Text, Spectral, Old Standard, Gentium Plus — elegant serif fonts that make your book look typeset by a professional, not printed from Word.

Smart Chapter Detection

Auto-detects chapters from headings, “Chapter”, “Part”, or --- separators. Supports English, French, Spanish, German, and Italian chapter names.

KDP-Compliant Margins

Gutter margins auto-adjust based on page count. Mirrored layout ensures the binding side always has proper clearance for perfect printing.

Drop Caps & Ornaments

Elegant drop caps at the start of each chapter and ornamental dividers between scenes for a polished, professional look.

Complete Front Matter

Half-title, title page, copyright, dedication, and auto-generated table of contents with dot leaders and page numbers.

Stop Publishing Ugly Books

Most self-published books look amateur because of bad formatting: wrong margins, system fonts, no headers, chapters that don’t start on the right page. This free tool fixes all of that in seconds.

Upload your .docx manuscript (or paste your text), pick a professional style preset, and get a print-ready PDF that looks like it came from a traditional publisher. Professional fonts like Crimson Text and Old Standard give your book the typographic quality readers expect.

The tool auto-calculates KDP-compliant gutter margins based on your page count (0.75″ for under 150 pages, 0.875″ for 150–400 pages, 1″ for 400+ pages), adds running headers, page numbers, drop caps, and ornamental chapter dividers.
