Why Convert MOBI to TXT?
Converting MOBI ebooks to TXT format is valuable when you need pure text content without any formatting, styling, or proprietary restrictions. TXT is the most universal and accessible text format, readable on literally any device, operating system, or text editor without requiring special software.
MOBI (Mobipocket) format was the primary format for Amazon Kindle devices before being superseded by AZW3/KF8. While MOBI files work well for reading on Kindle with formatting preserved, the proprietary binary format makes it difficult to access the raw text content. Converting to TXT extracts the pure text, making it perfect for reading, searching, analyzing, or repurposing content.
Plain text format is ideal for accessibility, as screen readers and assistive technologies handle TXT files flawlessly. It's also perfect for text analysis, natural language processing, indexing, searching, and archival purposes where formatting is unnecessary. TXT files are incredibly lightweight and will never have compatibility issues.
Note: Amazon announced in 2022 that they are phasing out MOBI format in favor of EPUB and KF8 for Kindle publishing. Converting your MOBI library to TXT ensures you have a universally accessible, future-proof version of your content that will be readable on any device for decades to come.
Key Benefits of Converting MOBI to TXT:
- Universal Access: Read on any device without special software
- Pure Text: Extract content without formatting or DRM
- Lightweight: Minimal file size, fast loading
- Accessibility: Perfect for screen readers and assistive tech
- Text Analysis: Easy to process and analyze programmatically
- Searchability: Quick full-text search capabilities
- Future-Proof: Will be readable forever on any platform

Frequently Asked Questions (FAQ)
Q: What is MOBI format?
A: MOBI (Mobipocket) is an ebook format originally developed by Mobipocket SA and later acquired by Amazon in 2005. It was the primary format for Kindle devices before being replaced by AZW3/KF8. MOBI files use PalmDOC compression and can contain DRM protection. Amazon announced in 2022 that MOBI is being phased out.
Q: What is TXT format?
A: TXT (Plain Text) is the simplest and most universal text file format containing unformatted text. It has no styling, images, or special features—just pure characters. TXT files can be opened on any computer, phone, tablet, or device using any text editor without requiring special software.
Q: Will formatting be preserved when converting to TXT?
A: No, TXT format does not support any formatting. All styling (bold, italic, fonts, colors), images, tables, and layout will be removed. Only the raw text content is preserved. This is by design—TXT is purely for plain text content. If you need formatting, consider converting to formats like RTF, DOCX, or HTML.
Q: Can I convert DRM-protected MOBI files?
A: No, DRM-protected MOBI files cannot be converted without first removing the DRM, which may violate terms of service or copyright law. This converter works with DRM-free MOBI files only. Many personal documents and DRM-free ebooks can be converted without issues.
Q: What happens to images in the MOBI file?
A: Images cannot be included in TXT files since TXT is a plain text format. Images from the MOBI file will be excluded from the conversion. If you need to preserve images, consider converting to formats like HTML, PDF, or DOCX that support embedded images.
Q: Can I edit the TXT file after conversion?
A: Yes, TXT files can be easily edited in any text editor including Notepad, TextEdit, Vim, VS Code, or any word processor. Simply open the file and make changes. The simplicity of TXT format makes it one of the easiest file types to edit on any platform.
Q: Why would I convert an ebook to plain text?
A: Converting to TXT is useful for text analysis, searching content, creating backups, accessibility with screen readers, reading on minimal devices (like e-ink readers), extracting quotes, or when you only need the content without formatting. It's also perfect for archival since TXT will be readable forever.
Q: What encoding does the TXT file use?
A: Most converters output TXT files in UTF-8 encoding, which supports all international characters and special symbols. UTF-8 is the universal standard and ensures your text will display correctly on any modern system. Some converters may offer options for ASCII or other encodings.
