What happens when you convert EPUB to HTML
- The chapters are read in their reading order from the EPUB's own table of contents and joined into one HTML file.
- Headings, paragraphs and emphasis are kept; images are left out so the page stays self-contained.
How to convert EPUB to HTML online
- Press "Choose EPUB files" and select one or more files, or drag them onto the box. You can add files of any size your device can hold in memory.
- There are no settings to choose: the converter keeps everything the target format can hold.

- Save each HTML with its download button. Close the tab and every trace of the files is gone from memory.
Why convert EPUB to HTML?
EPUB files usually come from e-books from stores other than Amazon and free e-book libraries. People convert them to HTML because HTML opens in any browser and keeps headings, lists, tables and links.
In short, EPUB is good at what it was made for, and HTML is the more practical choice when the file has to open, upload or print somewhere else. EPUB opens in Apple Books, Google Play Books, Kobo and most e-reader apps; a Kindle needs it sent through Send to Kindle, while HTML opens in every web browser.

About EPUB and HTML files
What is an EPUB file?
An EPUB is a ZIP archive of web pages, one per chapter, plus a file that lists their order. That is why its text can be extracted with ordinary web tools.
What is an HTML file?
HTML is the language of web pages. A converted document saved as HTML keeps its headings, lists, tables and links and opens in any browser.
EPUB to HTML not working? Common problems
- The result is empty. For PDFs, this means the pages are images without a text layer; use OCR through JPG to TXT instead.
- Some formatting is missing. Plain text and simple HTML have no place for page layout, fonts or colours; only structure and words are kept.
- Characters show as boxes in the PDF. The embedded font does not cover that script, such as Chinese or Hindi.

EPUB to HTML converter FAQ
Will I lose quality converting EPUB to HTML?
The text and its structure are kept; the page layout of the EPUB is not.
Why is the HTML a different size from the EPUB?
Plain text and simple HTML contain only words and tags, so the result is usually much smaller than the original.
Are my EPUB files uploaded anywhere?
No. The conversion runs inside this browser tab using open-source document libraries (mammoth.js, PDF.js and pdf-lib), so your files stay on your device. You can disconnect from the internet after the page and converter engine have loaded and it still works.
Can I convert several EPUB files to HTML at once?
Yes. Select or drop as many files as you like; they are converted one after another and each gets its own download button.
How do I open an HTML file?
HTML opens in every web browser. HTML is common for web pages, emails and documents meant to be read in a browser.
Is this EPUB to HTML converter free?
Yes. There is no sign-up, no watermark and no limit on how many files you convert. The site is paid for by advertising, and because conversions run on your device there is no server cost per file.
Can I convert EPUB to HTML on my phone?
Yes. The converter works in Safari on iPhone and iPad and in Chrome on Android. Converted files are saved to the Downloads folder.
