Our verdict on Lacuna

Lacuna is desktop publishing software for authors and small publishing teams converting DOCX manuscripts into finished eBooks and print files. It imports manuscripts with automatic section detection, applies premade or custom styles, handles layouts, and exports EPUB 2.0, EPUB 3.0, and print-ready PDF/X-1a files. Its local processing model suits publishers who want book production to remain offline on Windows or macOS, rather than working in a browser or a broader design suite.

Pricing is based on one-time machine licenses. The 1 Machine plan costs $149 and includes professional e-book and print formatting, Windows and Mac support, and lifetime updates. The 2 Machines plan costs $239, while the 3 Machines plan costs $339; both include the same listed capabilities and lifetime updates. A free, no-time-limit version supports evaluation, but final PDF and EPUB generation requires payment. This structure fits authors and small teams who prefer a perpetual purchase, though the starting price is significant for a book-focused application.

Lacuna’s strongest area is the conversion workflow. Pre-export preflight checks, automatic image compression, real EPUB rendering, device previews, and store-specific EPUB export address common steps between manuscript and distribution file. Offline, local document processing is also useful for teams that want files handled on their own machines. The trade-off is focus: Lacuna is aimed at book formatting rather than general desktop publishing, and it does not include AI features. Choose it for controlled, offline book conversion across Windows and Mac; consider another tool if you need a broader publishing system or want final exports before purchasing.
