Plain Text

Documents & Text

TXT files contain unformatted plain text with no styling, images, or layout information. They are universally readable by any device and operating system, making them the simplest document format.

Vorteilsvergleich

MOBI Vorteile

  • Universal Kindle support on every device ever released.
  • Very small file sizes for text-heavy books.
  • Mature tooling via Calibre and Amazon's KindleGen.
  • Simple container structure — easy to parse.

TXT Vorteile

  • Universally readable — every operating system, every editor, every programming language.
  • Zero metadata overhead: the file size equals the character count (for ASCII).
  • Safe to diff, grep, version-control, and pipe through command-line tools.
  • Immune to format obsolescence: a text file from 1970 still opens today.
  • Tiny footprint for structured data like logs or configuration.

Einschränkungen

MOBI Einschränkungen

  • Deprecated by Amazon for new uploads since 2022.
  • Poor support for rich typography (drop caps, ligatures, fixed layout).
  • No embedded fonts in the base format.
  • Proprietary container discouraged use outside Kindle.
  • Effectively a legacy format — new books go to AZW3/EPUB.

TXT Einschränkungen

  • No styling, images, or embedded structure — just characters.
  • Character encoding ambiguity (ISO-8859-1 vs UTF-8 vs Windows-1252) causes "mojibake".
  • Line-ending differences between OSes still cause subtle bugs today.
  • No way to carry hyperlinks, tables, or formatting without a convention on top (like Markdown).
