Convert Documents to TXTZ Online — Free eBook Converter
This free online converter transforms documents from a wide range of input formats into the TXTZ eBook format, giving you a lightweight, portable eBook file ready for compatible readers — no software installation or account required.
What is TXTZ?
TXTZ is a simple eBook container format closely related to plain-text eBooks. It is essentially a ZIP-compressed archive that holds a plain-text (.txt) source file along with optional metadata and image assets. Because the text content remains unformatted and human-readable, TXTZ files are extremely compact and compatible with a broad range of eBook reader applications that support the format, including Calibre and several open-source readers.
The format prioritises portability and simplicity over rich layout, making it a practical choice when you need a no-frills digital book that loads quickly and takes up minimal storage space.
Why convert to TXTZ?
There are several practical reasons to convert a document to TXTZ rather than a more complex eBook format:
- Maximum compatibility: Plain-text-based formats are supported by virtually every eBook management tool, especially Calibre, which can re-export TXTZ to dozens of other formats.
- Tiny file size: ZIP compression and stripped formatting keep TXTZ files very small, ideal for archiving or sharing large document collections.
- Easy editing: Because the core content is plain text, you can open and edit a TXTZ file with any text editor after unzipping.
- Intermediate conversion step: TXTZ is often used as a lossless intermediate format when converting between document types in Calibre-based workflows.
Supported input formats
The converter accepts a variety of common document and eBook source formats, including DOC, DOCX, PDF, RTF, HTML, EPUB, MOBI, FB2, LIT, LRF, ODT, TXT and more. Simply upload your file, and the tool will handle the conversion automatically — no configuration needed.
