Frequently asked questions
Why is this Pro?+
ZIP generation and multi-file output are Pro features. Single-file conversions stay free.
Can I customize filenames?+
Filenames derive from heading text + sequence number. Manual rename after extraction is straightforward.
What about frontmatter handling?+
Frontmatter is included only in the first file. Add chapter-specific frontmatter manually after splitting.
