What changes in this conversion

  • The content is read from the TXT file and written into EPUB. Anything EPUB has no way to represent is left out rather than approximated.

How to use

  1. Add your TXT file

    Drag the TXT file onto the drop area above, or click it to pick a file from your device. You can add several files at once.

  2. Confirm EPUB as the output

    EPUB is already selected as the output format on this page. Only the options this format actually supports show up, such as a page range or sheet selection.

  3. Run the conversion

    Press the convert button. Processing happens on your own device, so the time depends on your computer rather than a server queue.

  4. Download the EPUB file

    When it finishes, download the EPUB file. Converting multiple files gives you the option to download them together as a ZIP.

Frequently asked questions

Is converting TXT to EPUB really free?

Yes. TXT to EPUB conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.

Are my TXT files uploaded to a server?

No. The conversion runs entirely inside your browser using WebAssembly, so the TXT file never leaves your device. That is also why it works without an internet connection once the page has loaded.

Does the EPUB file get bigger than the TXT?

It can go either way. Both formats are lossless, so nothing is thrown away — the size difference comes from how each one packs the same data.

Is there a file size limit for TXT to EPUB conversion?

The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
