Features

🔄

Converts Both Ways

EPUB → TXT for reading or editing anywhere, and TXT → EPUB for a proper ebook with a table of contents.

📑

Automatic Chapter Detection

Built-in patterns for Chinese 第X章, English "Chapter N" and Markdown headings, plus your own regex with a live chapter preview.

🔒

Your Manuscript Stays Private

All parsing and packing happens in your browser. Nothing is ever sent to a server.

📚

Valid EPUB 3 Output

Generates content.opf, nav.xhtml and toc.ncx, so the file opens in Kindle, Apple Books, Calibre and Kobo.

🈶

Handles Legacy Encodings

Detects UTF-8 automatically and falls back to GBK, with manual UTF-8 / GBK / Big5 selection for older Chinese novel files.

🖼️

Cover and Metadata

Add a title, author, language and a JPG or PNG cover image before packing your EPUB.

📦

Batch EPUB Extraction

Drop several EPUB files at once and switch between the extracted results before downloading.

⚙️

Text Output You Control

Choose BOM for Windows Notepad, LF or CRLF line endings, whether to keep chapter titles, and blank-line collapsing.

Frequently Asked Questions

Is this EPUB converter free?
Yes. It is completely free, with no account, no watermark and no file-count limit.
Are my files uploaded to a server?
No. The EPUB is unzipped and rebuilt entirely in your browser using JavaScript, so your book never leaves your device. You can even use the tool offline once the page has loaded.
Will the EPUB I create work on a Kindle?
Yes. The output is a valid EPUB 3 with both nav.xhtml and toc.ncx, which modern Kindles accept via Send to Kindle. You can also convert it to other formats with Calibre.
How does the chapter detection work?
Each line of your TXT file is tested against a regular expression. Presets cover Chinese chapter headings, English "Chapter N" and Markdown headings, and you can write your own regex. The detected chapter list updates as you type, and you can delete any line that was matched by mistake.
My Chinese TXT file shows garbled characters. What can I do?
Old Chinese novels are often GBK-encoded. The tool tries UTF-8 first and falls back to GBK automatically, but you can also pick UTF-8, GBK or Big5 manually. Safari cannot decode GBK, so on Safari use a UTF-8 file.
Can it convert DRM-protected ebooks?
No. Files bought from stores with DRM cannot be opened by any browser-based tool. Only DRM-free EPUB files can be converted.
Are images and formatting kept when converting to TXT?
No. TXT is a plain-text format, so images, fonts and styling are dropped. Paragraph breaks and chapter titles are preserved.
