Convert MOBI to EPUB in your browser: drop a Kindle .mobi file and get back a standard EPUB 3 book for the e-readers and apps that don’t open Kindle formats. It is the usual fix for an old Mobipocket library, a DRM-free book that only came as MOBI, or a file you want to edit or read outside the Kindle world. This free MOBI to EPUB converter decompresses and rebuilds the book on your own device, so nothing is uploaded. The EPUB keeps the title and author, the text split into chapters with a table of contents, and the images. It does not copy the original styling, so your reader’s own font and layout take over.
How it works
- Drop the .mobi file, or up to 20 at once. Each card shows the title and author read from the book’s own metadata, or the reason a file can’t be converted.
- Check the chapter list: chapters are cut where the MOBI marks a page break and are named after their first heading. Untick any you want left out.
- Press Convert & download to save the .epub, or one ZIP with a report when you converted several books.
Questions
- Why was my MOBI file refused?
- The card names the reason. A book bought from the Kindle store is normally DRM-protected, and this tool does not remove DRM. A MOBI that uses HUFF/CDIC text compression is not supported yet. And a file that is not a Kindle book at all, such as a renamed PDF, is refused too, because the format is read from the file’s bytes rather than its name.
- Is the formatting kept?
- The structure is: headings, paragraphs, lists, block quotes, line breaks and images all carry over, with headings kept to three levels. The look is not. Bold, italics, fonts, colours and spacing are dropped, and the EPUB ships no stylesheet, so each reader shows it in its own default font: clean and readable, but plainer than the Kindle version.
- Will the EPUB have a table of contents?
- Yes. The converter writes an EPUB 3 navigation file listing every chapter you kept, named after its first heading, or Chapter 1, Chapter 2 and so on where a section has none. Title and author come from the MOBI’s metadata. The language is recorded as English, because it is not read from the MOBI file.
- Does my file get uploaded?
- No. The models and all processing run inside your browser on your own device. You can verify this yourself: open your browser’s DevTools, watch the Network tab, and process a file: there are no uploads. After the first visit most tools also work fully offline.
- Does this work on books with DRM?
- No. DRM-protected books (most storefront purchases) are encrypted, and this tool does not and will not break that encryption. DRM-free books (self-published, converted, or from DRM-free stores) convert fine.
- Will the PDF look exactly like my e-reader?
- EPUB is reflowable, with no fixed pages, so the PDF is one honest pagination of the book at a readable size: chapters, paragraphs and images in order. Complex fixed layouts may differ from a particular reader’s rendering.
