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.

The conversion that looks simplest is the one that quietly shifts a line break and pushes your last paragraph onto a page of its own. Here is what actually happens, and what to look at afterwards.

Why you cannot copy text out of a scanned PDF
Two PDFs can look identical and be completely different files. One contains text; the other contains a photograph of text. Only one of them can be searched, copied or converted to Word.
