About Torcul

Torcul typesets a Word (DOCX) or Markdown manuscript into a print-ready PDF interior, an EPUB that passes EPUBCheck and a cover sized to the final page count. It shows how each heading was read, so you can correct it before layout, and you see every page before you pay. Three interior designs, eight trim sizes from 5×8 to 7×10. Free checkers for KDP files run in your browser with nothing uploaded.

Who it is for
Independent authors and self-publishers creating print and ebook editions of their books.
Problem it solves
Self-publishing a book involves more than writing. Authors must format their manuscripts, prepare print-ready interiors, create EPUB files, and ensure their books meet publishing platform requirements. Professional formatting software can be expensive, while manual formatting in Word is time-consuming and error-prone. Torcul helps authors overcome these technical challenges without requiring expensive software or complex design skills.
The solution
Torcul turns a Word or Markdown manuscript into a print-ready interior PDF, EPUB, and book cover. Authors can preview every page, check their formatting, and make sure their book looks right before paying. With a simple browser-based workflow, Torcul makes professional book formatting accessible without expensive software or subscriptions.
What makes it unique
Unlike expensive desktop formatting software, Torcul works directly in your browser with no installation or subscription required. Authors can format their books, preview every page, and download print-ready PDF, EPUB, and cover files for just $29 per book. You only pay when you're satisfied with the result, making professional book formatting more accessible to independent authors.

Starting price: $29 for one book, paid once.
