Convert MOBI to TXT in your browser: drop a Kindle or Mobipocket .mobi file and download the book’s text as one plain UTF-8 file. Use it to listen with a text-to-speech app, search or count words, quote passages, or move an old Mobipocket book onto a device that reads nothing but text. The file is decompressed and read on your own device, and nothing is uploaded. Older MOBI files stored in the Windows-1252 character set are converted to UTF-8 on the way, so accented letters survive, and the text is split into chapters at the book’s own page breaks.
How it works
- Drop the .mobi file; DRM-free AZW and AZW3 files work too. The card shows the title, the author and the number of chapters found.
- Untick the chapters you don’t need. The Output is already set to Text.
- Press Convert & download to save the .txt, or drop several books and get one ZIP of text files with a report.
Questions
- How are chapters separated in the text?
- A MOBI book has no chapter files, only page-break markers, so the text is cut at each one. Chapters are separated by two blank lines and paragraphs by one, and headings are underlined with = or - signs, so the start of a chapter is easy to spot by eye or to find with a script.
- Can I convert several MOBI files to text at once?
- Yes, up to 20 books or 1 GiB per run, and EPUB files can be mixed in. Each book is converted in turn and one ZIP comes back with a .txt per book plus a report naming any that failed and why, such as a DRM-protected file. Books over the cap are listed as skipped, never silently dropped.
- 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.
