MOBI
Kindle e-book
MOBI is the e-book format older Kindles used. Amazon stopped accepting MOBI through Send to Kindle in 2022 in favour of EPUB, so it is now mostly found in old libraries.
Opens in Older Kindles and Calibre

How to convert MOBI to MD
Add your MOBI e-books
Drop MOBI files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
MD is already chosen
Press Convert. There is nothing else to set. The work happens in this tab.
Download
Save the MD, or download everything as one ZIP if you converted several files.
Why ToAny
Private by construction
The MOBI to MD converter is part of this page and runs inside your browser. Your e-books are never sent to ToAny or to anyone else.
No upload, no queue
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
Free, without an account
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
MOBI to MD: what to expect
MOBI is no longer accepted by Send to Kindle and is not opened by other e-readers. Markdown is plain text that stays readable and is easy to keep in version control. MOBI is at home in Kindles too old for newer formats; MD is the usual choice for READMEs, notes and documentation.
Both the older Mobi format and the newer KF8 (AZW3) are read, with the chapters in order and the pictures embedded; a book bought from the Kindle store with Amazon copy protection (DRM) is refused because its text cannot be read.
MOBI vs MD
MD
Markdown
Markdown is plain text with a few symbols for headings, lists, links and emphasis. It is readable as-is and converts cleanly to HTML, which is why developers and note-takers favour it.

Questions
Are my e-books uploaded anywhere?
No. The MOBI to MD conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
Is anything lost when converting MOBI to MD?
Text is kept. Formatting carries over only as far as MD supports it.
Can I convert several MOBI files at once?
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
How do I convert MOBI to MD on Windows, Mac, iPhone or Android?
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the MOBI file, press Convert and save the MD. There is nothing to install.
Is there a file size limit?
Yes. Files up to 150 MB are accepted; a larger one is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
