What this tool does
EPUB to HTML merges the whole book into one HTML file: chapters are concatenated strictly in reading order, a clickable table of contents is generated, and a small clean stylesheet is included — just open it in any browser to read offline.
Unlike TXT, basic structure such as paragraphs, headings and emphasis survives, which suits reading and archiving when plain text is too bare. Everything runs in your browser and nothing is uploaded.
Each chapter gets a stable anchor id (ch-1, ch-2, …), so the TOC links keep working even if you later edit or split the file. The document declares UTF-8 and a viewport, so it renders correctly on phones as well.
How to use
- Drop your .epub above Up to 50MB per file. DRM-protected books are rejected outright.
- Choose TOC options TOC anchors are on by default; turning off section wrapping yields flatter div markup.
- Download and open in a browser The single HTML file has no external dependencies — open it offline or publish it as a page.
FAQ
Do images still display in the HTML?
No. Images inside the EPUB are not inlined, so their references break — a known limit of single-file output.
Is the table of contents clickable?
Yes. Every chapter gets a stable anchor (ch-1, ch-2, …) and TOC entries link to them.
Can DRM-protected books be converted?
No. The tool never attempts decryption and errors out when encryption is detected.
Is my file uploaded?
No. Unpacking and merging happen entirely in your browser.
Are the original fonts and colors kept?
No. A built-in consistent stylesheet is used instead, which usually reads better than the original.
Does it render well on phones?
Yes. The document declares a viewport, limits line width, and scales images to the container.
