Plain text strips formatting entirely — no fonts, no layout, no images. Convert to TXT when you need to pipe content into a script or CSV import, or when a legal / archival requirement specifies "no formatting". Also the right choice for extracting the substantive content from a PDF for OCR post-processing or text-analysis workflows.
Turn your ebook into a document format for printing, sharing, editing, or archiving — text content, chapters, and images are preserved.
Drag and drop your AZW3 ebook or click to browse. Supports ebooks with text, images, chapters, and embedded metadata. Batch upload multiple files at once.
Our engine extracts text content, chapter structure, and images from your AZW3 ebook and converts them into a properly formatted TXT document ready for viewing or editing.
Download your converted TXT document instantly. Text formatting, headings, and images are preserved. No watermarks or quality loss.
Plain text files open instantly on every operating system, programming environment, and device ever created. TXT is the most universally compatible file format in computing — nothing fails to read it.
TXT files contain pure text with no fonts, styles, images, or macros. They never have compatibility issues, never carry viruses in macros, and never require specific software versions to open.
A TXT file contains only the characters you need with no overhead. A 10-page document might be just 20 KB as TXT compared to hundreds of KB as DOCX, making TXT ideal for storage and transfer.
TXT files are the foundation of configuration files, scripts, data exchange, and log files. Every programming language can read and write TXT natively without importing libraries or parsers.
Plain text is the most durable digital format. TXT files created decades ago still open perfectly today. For content that must remain readable for years or centuries, TXT is the safest choice.
Technical comparison of the two formats — useful for deciding which to use, or for confirming what changes during conversion.

AZW3, also known as Kindle Format 8 (KF8), is Amazon's modern ebook format introduced in 2011 as the successor to MOBI. Built on HTML5 and CSS3, AZW3 supports advanced typographic features including embedded fonts, drop caps, SVG graphics, fixed-layout pages, and responsive design that adapts to different Kindle screen sizes. It provides a significantly richer reading experience compared to the older MOBI format.
AZW3 is Amazon's proprietary format and only works on Kindle devices and Kindle reading apps. It takes full advantage of Kindle's enhanced typesetting engine, supporting features like X-Ray, Word Wise, and improved font rendering. AZW3 files use more efficient compression than MOBI, resulting in smaller file sizes. While AZW3 is the preferred format for sideloading content to modern Kindles, it cannot be read on other eReaders like Kobo, Nook, or Apple Books without first converting to EPUB.
