About the MOBI to EPUB
EPUB is the e-book format almost every reader understands, including Kobo, Apple Books, Google Play Books and most phone apps, while MOBI is mostly for older Kindles. This tool converts a DRM-free MOBI or AZW book into a standard EPUB 3 file in your browser. It keeps the text, the headings and the lists, and builds a table of contents from the chapter headings. Pictures, fonts and the cover are not carried over, and the page tells you how many pictures were left out. Nothing is uploaded, and protected books are refused with a clear message.

MOBI and EPUB in plain words
Both are reflowable formats, which means text adapts to the screen size. MOBI came from Mobipocket and was adopted by early Kindles. EPUB is an open standard maintained by the publishing industry and is the format most apps and e-readers use. Converting from MOBI to EPUB makes a book readable on a much wider range of devices.
What this converter keeps
The text of the book, paragraph by paragraph, headings in three levels, and bulleted or numbered lists. Chapters are split at first-level headings so the table of contents lists them. The book title is taken from the MOBI file, and the new EPUB gets a fresh unique identifier.
- Text, headings and lists
- Chapter list in the table of contents
- Title taken from the original file
What it leaves out
Images are skipped because the EPUB written here is text only. Fonts, the cover, colours and any special layout are also not carried over. If pictures matter, convert to PDF instead with MOBI to PDF, which keeps JPG and PNG pictures.
Protected and unusual books
Books with DRM cannot be read by this tool and are refused with a plain message. KF8 books (AZW3) and a rare compression type are also not supported. Look for a DRM-free copy from the publisher, a library service or a public-domain source.
Phone and computer
On a phone, choose the book from your files and save the EPUB to Files or your reading app. On a computer, drop the file on the page. The conversion happens in seconds for a normal novel and does not need an internet connection once the page has loaded.
Good to know
If the book has no first-level headings, the EPUB becomes a single long chapter, which is fine for reading but gives a one-line contents list. Open the file in your reader before deleting the original, and keep the MOBI if you want the pictures. If you need a document, convert the new file with EPUB to PDF, and use PDF to EPUB for the other direction.

Frequently asked questions
Will the EPUB open on my Kobo or in Apple Books?
Yes. It is a standard EPUB 3 file with a navigation document, which these readers accept.
Are pictures and the cover kept?
No. This converter keeps the text, headings and lists. The result note tells you how many pictures were left out. The book gets no cover image.
Can it convert books bought from Amazon?
Only if they have no DRM. Store-bought Kindle books are normally protected and cannot be read by any converter. Public-domain books and DRM-free purchases work.
Does it work with AZW3 books?
Not yet. AZW3 (KF8) uses a newer layout. Classic MOBI and AZW files are supported.
Will the formatting match the original?
The structure is kept, but the look is the reader's own. Fonts, colours and exact page breaks of the MOBI are not copied, which is normal for reflowable e-books.
Is my book uploaded?
No. The whole conversion runs in your browser.
