What happens when you convert MOBI to TXT
- The MOBI is converted by Calibre, the widely used open-source e-book manager, on our conversion server.
- The book's text comes out as UTF-8 plain text, chapter after chapter, with every language and alphabet kept.
- Images, styling and the table of contents are left out; only the words remain.
- Books bought from a store usually carry DRM, which no honest converter removes. DRM-free MOBI files convert normally.
- This conversion runs on our server: the file is uploaded, converted, and deleted together with the result as soon as the result has been sent back to you. Nothing is kept. Files up to 25 MB are accepted.
How to convert MOBI to TXT online
- Press "Choose MOBI files" and select one or more files, or drag them onto the box. Files up to 25 MB each can be converted.
- There are no settings to choose: the converter keeps everything the target format can hold.
- Press "Convert to TXT". The file is uploaded to our conversion server, converted in a few seconds, and deleted together with the result as soon as the result is sent back.
- Save each TXT with its download button. Our server has already deleted both your MOBI and the TXT by then.
Why convert MOBI to TXT?
MOBI files usually come from older Kindle e-readers and e-books from the 2000s. People convert them to TXT because plain text opens everywhere and is easy to search, copy, edit and paste into other tools.
In short, MOBI is good at what it was made for, and TXT is the more practical choice when the file has to open, upload or print somewhere else. MOBI opens on older Kindles and in the Kindle and Calibre apps, while TXT opens in every browser, text editor and phone.

About MOBI and TXT files
What is a MOBI file?
MOBI was the Kindle's original format. Amazon has since moved to AZW3 and KFX and no longer accepts MOBI through Send to Kindle, which now takes EPUB instead.
What is a TXT file?
A TXT file holds nothing but characters: no fonts, images or layout. Modern text files are usually UTF-8, which covers every language.
MOBI to TXT not working? Common problems
- "Files up to 25 MB can be converted." Server conversions have a size limit. Most of a large book is its pictures; a copy with smaller images will convert.
- "The conversion took too long and was stopped." Very long or complex files can pass the 90 second limit. Split the file and convert the parts.
- The book will not convert. Books bought from a store usually have DRM, which encrypts them; no legitimate converter removes it.
Convert MOBI to TXT from the command line
This page uses Calibre. Installed on your computer, its ebook-convert command does the same conversion:
ebook-convert input.mobi output.txtConverting on your own computer keeps the file entirely local, which is worth it for very large or very sensitive documents. For everything else, the converter on this page does it without installing anything.
MOBI to TXT converter FAQ
Will I lose quality converting MOBI to TXT?
The words are kept exactly; images and formatting are not, because the target has no room for them.
Why is the TXT a different size from the MOBI?
Much smaller than the MOBI, because only the text is kept.
Are my MOBI files uploaded?
Yes, for this conversion. A faithful MOBI to TXT conversion needs Calibre, the open-source e-book manager, which cannot run in a browser. The file travels over an encrypted connection, is converted in a private temporary folder, and is deleted together with the TXT as soon as the result has been sent back to you. We do not keep, read or share it.
Can I convert several MOBI files to TXT at once?
Yes. Select or drop as many files as you like; they are converted one after another and each gets its own download button.
How do I open a TXT file?
TXT opens in every browser, text editor and phone. TXT is common for notes, logs, extracted text and anything that must open everywhere.
Is this MOBI to TXT converter free?
Yes. There is no sign-up and no watermark. Because this conversion uses our server, there is a fair-use limit of 25 MB per file and a number of files per hour, which stops the service being overloaded.
Can I convert MOBI to TXT on my phone?
Yes. It works in Safari on iPhone and iPad and in Chrome on Android. The conversion happens on our server, so it is as fast on a phone as on a computer; the TXT is saved to your Downloads folder.
