EPUB
The EPUB build flow, reflowable versus fixed layout, and validation.
Build a print-ready PDF from your manuscript or a version.
Build a PDF
Choose the scope and start the build.
Open Build Book, choose PDF, and review the summary. Free builds cover the first 25 ordered pages; Pro builds the whole book. Pick an output location and press Build; the progress card tracks the job.
- -Free builds the first 25 ordered source pages.
- -Pro builds every page in reading order.
- -One page in the manuscript becomes one page in the PDF.
The Build Book Server Lease
Builds are authorized on demand.
Before a build starts, the app asks the Build Book Server for a short lease. The lease lasts six hours and is reused across builds, so repeated exports do not re-authorize every time.
Build Logs
Find build details in Settings.
The Logs Viewer in Settings lists every build session with its output path and status. You can copy a session log or clear old ones.
