Convert EPUB ebooks to Markdown — with translation

EPUB keeps chapter and reflow structure for e-readers, not for editing or quoting in notes. FileWorks converts EPUB into Markdown you can edit, search, translate into 19 languages, and feed into docs tools or LLM context.

Open workspace and convert

What you get

Accepts standard .epub ebook files
Chapter headings and text structure map to Markdown
Optional translation into 19 languages in the same pass
Download Markdown, TXT, HTML, or re-export via the Convert API

How to convert

Open the FileWorks workspace and drop an EPUB file.
Optionally pick a translation language.
Convert, then edit the Markdown chapters or download the result.

Tips to get clean Markdown

If chapter breaks disappear in the output, check that the source EPUB actually uses heading tags for chapter titles — some poorly structured EPUBs rely on page breaks alone, which carry no heading information.
For long books, convert and review one chapter's Markdown first before translating the whole file, since translation uses AI page credits or allowance.
Image-heavy EPUBs (comics, illustrated books) convert the surrounding text well but won't meaningfully OCR embedded illustrations — this converter is for text-structured ebooks, not scanned picture books.

How this compares to typical online converters

Ebooks are built for reflowable reading, not editing — here's what usually gets lost elsewhere.

Aspect	FileWorks	Typical free converter
Chapter structure	Chapter headings map to Markdown heading levels	Often flattened into one long, untitled block of text
Footnotes / endnotes	Kept inline near their reference where the EPUB structure supports it	Frequently dropped or separated from context
Translation	Optional translation of the full book's text into 19 languages	Not offered
Output options	Markdown, TXT, or HTML re-export	Usually plain text only
File size	Up to 50 MB per EPUB	Often capped well below typical ebook sizes

Who uses this converter

Readers and researchers pulling ebook excerpts into Markdown notes
Developers and AI agents chunking ebook chapters for RAG ingestion
Translating an EPUB book's text into another language in one pass
