    The details

    What happens when you convert between text formats

    Nothing but characters. The simplest file format and the most compatible. The text is parsed and re-emitted in the target structure — headings become HTML tags, rows become JSON objects, and so on. The result is a the format the web is built on. a document that a browser knows how to lay out, produced entirely inside your browser.

    What survives

    • Every piece of content
    • The hierarchy, wherever the target format can express it

    What changes

    • The exact formatting, which is replaced by the target format's own conventions
    • Anything the target format cannot represent

    Where it goes wrong

    • Markdown extensions beyond the original specification are not converted
    • CSV parsing depends on the delimiter and the quoting being conventional

    Why anyone would do this

    The same content, in the shape the next tool in the chain actually accepts.

    About the format

    Nothing but characters.

    A sequence of bytes, usually UTF-8, with a line ending convention. There is no header and no metadata.

    Where it is good
    • Any device on earth can open it
    • Searchable, greppable and scriptable
    • Zero conversion risk, because there is nothing to lose
    Where it falls short
    • No formatting of any kind
    • Encoding matters — an old file may be in a legacy code page
    • Line endings differ between Windows and Unix
    You will find it on
    Programmers, terminal users, every text editor ever

    The thing people miss

    Converting a PDF to plain text is often the only way to search inside a document you cannot otherwise edit.

    About the target

    The format the web is built on.

    A tree of elements and attributes, usually with CSS for styling and JavaScript for behaviour. The browser builds the page from it at request time.

    • Reflows to any screen size on its own
    • Semantic markup makes a document readable by a screen reader
    • Links, images and forms are all part of the format

    Questions

    TXT conversion questions

    What actually happens to my TXT file when I convert it to HTML?

    The text is parsed and re-emitted in the target structure — headings become HTML tags, rows become JSON objects, and so on. So the TXT file is unpacked, the content is laid out, and the result is written out as HTML. Every piece of content survives unchanged.

    Will converting TXT to HTML reduce the quality?

    Partly. Some formatting is approximated because the two formats describe layout differently. The text itself is never re-typed, so no words are lost.

    Is my TXT file uploaded to a server?

    No. This TXT to HTML conversion runs as JavaScript inside your browser tab. The file is read from your device and the result is written back to your device, so there is no upload step, no file-size limit and no copy of your TXT file on any server.

    Do I need an account or will there be a watermark?

    Neither. There is no sign-up step, no email capture and no watermark on the output. The only limits are the ones your own device imposes.

    What is the most common mistake people make when converting TXT to HTML?

    Markdown extensions beyond the original specification are not converted

    Why would somebody convert TXT to HTML at all?

    The same content, in the shape the next tool in the chain actually accepts. In short: stripping a document down to just its words

    Something most people do not know about TXT?

    Converting a PDF to plain text is often the only way to search inside a document you cannot otherwise edit.
