How do I turn a DOCX manuscript into a publishable EPUB ebook?
+
Upload the DOCX and the converter parses heading structure to detect chapters, then builds a reflowable EPUB container with one chapter per ebook section, a generated TOC, and cover-art slot. The result is ready to upload to Kindle KDP, Apple Books, or Kobo.
Does the converter auto-detect chapters in my DOCX?
+
Yes — Heading 1 / Heading 2 styles in the DOCX become EPUB chapters by default. If your DOCX uses inconsistent headings, the advanced "chapter marker" option lets you specify a regex (e.g. `^Chapter \d+`) to override the heuristic.
Will the EPUB have a clickable table of contents?
+
Yes — detected chapters auto-populate the EPUB's NCX / nav.xhtml so every reader displays a proper chapter list. Apple Books, Kobo, and Calibre render it on the contents page; Kindle uses it for the "Go To" menu.
Can I add a cover image when converting DOCX to EPUB?
+
Yes — drop a cover image (JPG / PNG, ideally 1600×2400) alongside the DOCX in the upload, and we embed it in the EPUB as the official cover. Retailer storefronts pick up this image automatically when you upload the EPUB.
How do I set metadata (author, title, ISBN) on the EPUB?
+
The metadata form appears after upload — fill in title, author, language, publisher, and ISBN, and we write them into the EPUB's OPF block. KDP / Apple Books / Kobo all read this metadata when ingesting your EPUB.
What about images and figures in the DOCX?
+
Inline images in the DOCX (Word picture insertions, HTML `<img>`, PDF embedded figures) are extracted and re-embedded in the EPUB at the same paragraph anchor. PDF vector graphics are rasterized at 300 DPI before embedding.
Does the EPUB keep my DOCX typography (italics, smart quotes, drop caps)?
+
Italics, bold, smart quotes, em-dashes, and en-dashes all round-trip. CSS-style drop caps are added via EPUB CSS where supported (EPUB 3, AZW3). Older readers fall back to plain capitalization — the manuscript content is unchanged.
Can I make the EPUB compatible with both Kindle and other readers?
+
EPUB EPUB works on every reader except older Kindles. For maximum compatibility, generate EPUB here and then convert to AZW3 / KF8 via /epub-to-azw3/ — most authors ship both formats. KDP also accepts EPUB directly and converts internally.
Is my DOCX manuscript private during EPUB conversion?
+
Yes — uploaded DOCX files (especially unpublished manuscripts) are processed in isolated workers and deleted within minutes. We never read, retain, or train on manuscript content.
How long does DOCX to EPUB conversion take for a full novel?
+
A 300-page DOCX typically converts to EPUB in 10-30 seconds. PDF source is slower (text extraction + reflow) — expect 1-3 minutes for an image-heavy 400-page PDF.
Why does my EPUB have weird line breaks after conversion?
+
Most often the DOCX used hard line breaks at the end of every line (common in plain text or OCR'd PDFs) instead of paragraph breaks. Turn on the "smart paragraph reflow" advanced option — it merges hard-wrapped lines back into proper paragraphs in the EPUB.
Can I preview the EPUB before publishing it on Kindle / Kobo?
+
Yes — download the EPUB and open it in the free Calibre desktop app or the reader's preview tool (Kindle Previewer, Apple Books on Mac). Both render the exact pagination retailers will use, so you can catch layout issues before going live.
