Paste text or open a UTF-8 .txt file, choose how chapters are divided, and create a reflowable EPUB 3 in this browser tab. The chapter preview shows the exact titles the converter has recognized before you download. Blank lines make paragraphs; single line breaks inside a paragraph remain line breaks. This is useful for a clean novel draft, essay collection, or notes that have a readable order. It does not infer typography or recover images from a format that contains only text.
01Visible chapter plan
Recognizable heading lines such as ‘Chapter 1: Arrival’ and ‘第一章 初见’ start chapters when splitting is enabled. Switch splitting off to keep everything in one chapter. The preview reports the planned chapter count and labels, so a false break can be fixed in the input before export.
02Local, editable input
Paste into the editor or choose a .txt file of up to 4 MB. You can correct spacing, headings, or accidental characters in the same editor. The text, file name, title, author, and output are held in the current tab; this tool does not submit manuscript content to a conversion server or analytics.
03A navigable EPUB 3 file
The download contains ordered XHTML chapters, a table of contents, package metadata, a stylesheet, and the EPUB container files. It is a new file, so the source TXT on your device is not replaced. Open the result in a reader to check how paragraphs and navigation actually behave.
