TXT → EPUB
Converting a novel from Plain text (.txt) to EPUB (.epub) is a routine step in practice — EPUB is the universal e-book format: it adapts to any screen and font size, and carries a table of contents. Fortunately Plain text and EPUB are structurally close, so there is not much to lose. Below we explain in detail how Plain text becomes EPUB and what to watch out for, and the page ends with a converter that does the job right in your browser — nothing is uploaded, the file never leaves your machine.
What is TXT?
TXT is plain text: nothing but characters and line breaks, with no presentation information at all. That makes it the smallest and most compatible option — from the most basic feature phone to any operating system, there is almost no software that cannot open it. Most Chinese web novels circulate as TXT, and it is the easiest format to copy, search, batch-process and convert further. The cost is that it stores no images, colours, tables or table of contents, and there is nowhere to keep the title and author, so it behaves more like a clean body of text than a complete book.

What is EPUB?
EPUB is the most portable e-book format outside the Kindle ecosystem. It is really a ZIP archive holding XHTML content, CSS, images and a manifest that fixes the reading order. Because content and presentation are stored separately, the same file re-lays-out itself for a phone, a tablet or a desktop, and the reader can change the font size at any time. The table of contents, cover, title and author all have standard places, so library software recognises and sorts the book correctly. For text-heavy fiction, EPUB is usually the safest format to distribute and to keep long term. Read the EPUB format guide

How to convert TXT to EPUB
TXT carries no chapter markers — a heading is just a line that looks like one. Before converting, confirm the text has been split correctly (a regex matching chapter patterns), otherwise the whole book becomes one un-navigable block inside EPUB or Kindle.
EPUB is not just a ZIP: it must contain mimetype (as the first, uncompressed entry), META-INF/container.xml, the content OPF and a nav document. Miss one and readers report a corrupt file, so prefer a mature converter over hand-building the archive.
The source contains no images, so the result has no cover or illustrations. EPUB/Kindle library views then show a blank placeholder — add a cover manually afterwards or the title is unrecognisable on a shelf.
The source carries no metadata at all — plain-text formats such as TXT and Markdown are the classic case — while the target expects a title and author. Converters fall back to the filename, so libraries fill up with "Untitled" or titles still carrying the .txt or .md suffix — fill them in during conversion.
Chapter headings in the source are ordinary lines while the target demands a real table of contents. Converters try to match patterns such as "Chapter N"; when the match is poor the TOC is garbled or the book has a single chapter. Check that TOC entries match the actual chapter count.

These settings are written into the EPUB. The font size is relative, so readers can still adjust it themselves.
The conversion runs entirely in your browser — your file is never uploaded.
