A book saved off the web is usually one multi-megabyte text file: no table of contents, no way to find your place, and often an encoding that shows up as garbage. This tool turns it into a proper EPUB — chapter lines become a real table of contents, the encoding is repaired, and title, author and cover are filled in.

## How to use

1. Pick one or more TXT files (several files are joined in order)
2. Fill in the title and author, and choose a cover if you have one
3. Confirm how chapters are detected, then click Convert to EPUB
4. Check the chapter list and the structure self-check, then download

## Features

- Detects Chapter 7, Part IV and Chinese chapter headings automatically
- Auto-detects GBK / Big5 / Shift_JIS so garbled text never reaches the book
- Title, author, language, description and cover in one pass
- Built-in self-check for mimetype, XML, manifest and navigation
- Very long chapters can be split by length so readers stay responsive

## FAQ

### What if chapter detection misses?

Switch to Custom regex and write your own; it is matched line by line and a matching line becomes the chapter title. To split on a row of asterisks, for example, use ^\*+$. You can also pick One chapter per file and split the text yourself.

### Can a sentence mentioning a chapter be mistaken for a heading?

Almost never. A heading line has to be short and the number must be followed by whitespace, punctuation or the end of the line, so a sentence that continues past the number is left alone.

### Will it work on a Kindle?

Yes. Recent Kindle firmware reads EPUB directly, so Send to Kindle is enough; for very old models convert to AZW3 with Calibre.

### How is the encoding repaired?

By scoring bytes: valid UTF-8 is used as-is, otherwise GBK, Big5, Shift_JIS and EUC-KR are scored on how plausible the resulting characters look. If the preview still looks wrong, set the encoding by hand.

### Do Markdown files work?

Yes. Choose Markdown headings and the first two heading levels become chapters; deeper hashes are stripped and the text stays as a paragraph.
