Does this support .docx files?

No. True .docx parsing requires server-side processing. This tool accepts pasted plain text or basic HTML and produces a valid EPUB 3.0 file entirely in your browser.

Will my content be uploaded anywhere?

No. Everything runs in your browser. Your text never leaves your device.

Which e-readers support EPUB 3.0?

Most modern e-readers and apps support EPUB 3.0, including Kindle (via send-to-Kindle), Apple Books, Kobo, Adobe Digital Editions, and Calibre.

Can I include formatted text?

Yes. If you paste HTML (e.g. , , , ), it will be embedded directly in the EPUB content document. Plain text is wrapped in paragraph tags automatically.

What is the maximum size?

There is no hard limit imposed by the tool, but very large texts (hundreds of thousands of words) may slow down browser-side ZIP assembly.
