About TXT and HTML

Plain Text .txt

Just characters. No fonts, no sizes, no layout — which is exactly why it will still open, unchanged, in fifty years.

Good for

  • Universally readable, now and indefinitely
  • Tiny, and works with every text tool ever written
  • Nothing hidden — what you see is the whole file

Trade-offs

  • No formatting, images or structure whatsoever
  • Character encoding must be right or accents break
  • Line endings differ between Windows and everything else

text/plain

HTML .html

The markup language of the web: text wrapped in tags that describe structure, which a browser then renders.

Good for

  • Opens in any browser on any device
  • Structural and accessible when written properly
  • Styleable, linkable and searchable

Trade-offs

  • Appearance depends on the renderer and its stylesheet
  • Images and styles usually live outside the file
  • No fixed pagination — awkward to print predictably

What changes when you convert TXT to HTML

Read as UTF-8

A TXT is a text file, and a text file does not record which encoding it uses — that is the one thing the format cannot tell you about itself. We read it as UTF-8, which is right for essentially anything produced this decade. A file saved long ago in a regional encoding can arrive with accented characters mangled, and the fix is to re-save it as UTF-8 before converting rather than after. Tabs and spaces used to line columns up will also shift once the text is set in a proportional typeface.

The markup is sanitised

The HTML we produce is filtered down to a safe set of elements and attributes: scripts, event handlers and embedded objects are removed rather than carried through. This matters because converted files get opened in browsers, and a converter that faithfully preserved a script would be a way of passing one along. Structural markup, links, images and tables all survive.

Layout has to be invented

A text file carries no formatting at all, so the converter supplies what HTML requires: a readable typeface, sensible margins and paragraph structure. Any alignment achieved with spaces or tabs in the original will shift, because a proportional typeface does not put characters on a fixed grid.
