EPUB to HTML
Turn any EPUB into a single self-contained HTML file — every chapter in reading order, the book's styles merged in, and all images embedded. One file you can open offline, archive, print or edit anywhere. Everything happens locally in your browser; your book is never uploaded. Free, no accounts, no limits.

How to convert EPUB to HTML
Select your EPUB file
Open the book from your device. It is read by your browser directly — nothing is uploaded anywhere.
Convert to one HTML file
Each chapter is read in book order and merged into a single HTML document — styles combined, images embedded, a table of contents added on top. A progress bar follows along while it runs locally.
Download the HTML file
Save the self-contained .html file and open it anywhere — any browser, offline, no reader required.
An EPUB is HTML in a box
Inside every EPUB is a zip archive of XHTML documents, stylesheets and images held together by a package manifest. Converting to HTML is therefore less a translation than a repacking: the chapters are stitched back into one continuous document, in spine order, exactly as the book was meant to be read.
Because the source is XHTML rather than scanned pages, the output is real text — selectable, searchable, friendly to screen readers, and ready for any further processing.
Why a single HTML file
One .html file with everything inside is the most portable form an e-book can take. Double-click it and it opens in any browser on any operating system — no reader app, no plugin, no internet. That makes it ideal for offline reading, long-term archiving, sharing a book as one attachment, or printing straight from the browser.
It is also a natural editing format: open it in any HTML editor or feed it into other tools, and the full structure — headings, lists, tables, footnotes — is preserved.
Expect larger files
Images are embedded as base64 data, which adds roughly a third to their size compared with the compressed EPUB, so a graphics-heavy book produces a noticeably larger HTML file than its source. Text-only books stay tiny. For very large outputs the tool keeps going and tells you the result, so there are no surprises.
Frequently asked questions
Are images kept in the HTML file?
Yes. Every image stored in the EPUB is embedded directly into the HTML as base64 data, so covers, illustrations and diagrams travel inside the one file — they render even when you are completely offline.
What happens to the book's styling?
The stylesheets inside the EPUB are merged into a single embedded style block, and a minimal fallback style guarantees readable text, line spacing and image scaling. Layout features that depend on a dedicated e-reader, such as fixed pagination, are approximated by the browser.
Do internal links and footnotes still work?
Links that point within the same chapter keep working exactly as before. Cross-chapter links jump to the beginning of the target chapter — chapter-internal anchors cannot be mapped when everything merges into one file. External web links are preserved as-is.
My output file is very large — why?
Images embedded as base64 take about a third more space than they do inside the compressed EPUB, so picture-heavy books grow noticeably. Text-only books stay small. The tool warns you when the output exceeds 80 MB, but always finishes the conversion.
Can I open the HTML file offline?
Yes. The output is fully self-contained: text, styles and images all live inside the file, and it makes no network requests of any kind. Copy it to a USB stick, email it, keep it for years — it will open the same way.
Is my book uploaded to a server?
Never. The conversion runs entirely in your browser — you can verify it yourself: open your browser's network inspector while converting and you will see zero uploads.
Is this EPUB to HTML converter really free?
Yes. Every tool on iloveepub is free, with no accounts, no credits and no daily limits. The site is supported by ads, not subscriptions.
