Convert TXT to EPUB Free — Create a Valid Ebook from Plain Text

This tool converts plain text files to EPUB 3 format entirely in your browser. Set a title and author in the options, click Create EPUB, and download a valid ebook ready for Kobo, Apple Books, or the Kindle app. JSZip builds the EPUB container locally on your device. No file is uploaded and no account is required.

How to Convert a TXT File to EPUB

Drop your .txt file into the upload area or click to select it. The tool reads the file and shows a word count. Enter a book title in the options panel. The filename is used as a fallback if you leave it blank. Add an author name, or leave it as "Unknown author." Click Create EPUB. The file downloads immediately and a preview of the first 500 characters appears so you can confirm the content was read correctly.

The tool detects paragraph breaks from blank lines in your text file. Short lines followed by blank lines, or lines in all caps, are treated as chapter headings and rendered as H2 elements inside the ebook. All other lines become paragraphs.

What Is an EPUB File?

EPUB is the open ebook standard maintained by the W3C. An EPUB file is a ZIP archive with a specific internal structure. It contains XHTML chapter files, a CSS stylesheet, a metadata descriptor called content.opf, and a navigation document. This structure makes EPUB compatible with virtually every non-Kindle e-reader on the market, including Kobo, Apple Books, Adobe Digital Editions, and reading apps like Moon+ Reader.

This tool generates EPUB 3, the current version of the standard. EPUB 3 adds full HTML5 support, better accessibility metadata, and improved table of contents handling compared to the older EPUB 2 standard. Most modern e-readers and reading apps support EPUB 3 without issue.

Does EPUB Work on Kindle?

Kindle devices and the Kindle app have a specific compatibility history with EPUB. Older Kindle hardware released before 2022 does not open EPUB files natively. For those devices, you'd need to convert the EPUB to MOBI or AZW3 using a tool like Calibre before transferring it over USB.

The Kindle app for iOS and Android has supported EPUB directly since a 2022 update. Amazon's free "Send to Kindle" web service also accepts EPUB files and converts them automatically on Amazon's side before pushing the ebook to your device. If you're unsure which approach applies to your Kindle, check the firmware version in your device settings.

How Does the Tool Embed Metadata?

The title and author you enter are written into the EPUB's content.opf metadata file using the Dublin Core standard. This is the metadata format all major e-readers and library management apps read when displaying book information. When you add the EPUB to your library in Kobo, Apple Books, or Calibre, the book appears under the exact title and author you specified during conversion.

A unique UUID identifier is also generated automatically and stored in the metadata. This prevents library apps from confusing different books that share the same title or author name.

TXT to EPUB vs. EPUB to TXT: When to Use Each

This tool converts in one direction only: from plain text to EPUB ebook. It takes a raw .txt file and packages it into a valid, structured ebook container. The reverse operation, extracting the plain text content from an existing EPUB, is handled by the EPUB to TXT tool. Use that tool when you want to pull the text out of an ebook for editing, translation, or long-term archiving as a plain text document. Together, the two tools let you move content freely between formats without losing the text.
