TXT to EPUB Converter Online (Free, No Upload)
Convert TXT or plain-text files into EPUB3 ebooks online. Select one file, multiple files, or a folder; choose UTF-8 or GB18030 encoding; and split long text into chapters using blank lines. Processing stays in your browser, so source files are not uploaded.
How the Conversion Works
The converter reads each TXT file locally, decodes it with the encoding you choose, splits the text into chapters, and packages the result as a standards-compliant EPUB3 file. Converting a single file downloads one EPUB; converting multiple files or a folder exports a ZIP package with one EPUB per source file.
Choosing the Right Encoding
Use UTF-8 for most modern text files. If Chinese characters look garbled in the preview, switch to GB18030 and preview again — older Chinese TXT files are often saved in GBK/GB18030 rather than UTF-8.
Chapter Splitting
Long TXT files read poorly as one continuous block. Enable splitting by blank lines to break the content into readable EPUB sections, which also makes the table of contents useful on e-readers.
Privacy
All conversion happens in your browser. Your books never leave your device, there is no upload queue, and the tool keeps working offline once loaded.
TXT to EPUB FAQ
Which encoding should I choose for TXT files?
Use Auto or UTF-8 for most modern text files. If Chinese characters are garbled, choose GB18030 and convert again.
How does chapter splitting work?
Choose two or three consecutive line breaks as chapter boundaries. Each resulting section becomes an EPUB chapter and table-of-contents entry.
Can I convert multiple TXT files at once?
Yes. Select multiple TXT files or a folder to download a ZIP containing one EPUB for each source file.
