Free online CSS to TXT converter

A document-management system, archive, or basic editor may accept only files with a .txt extension. Because CSS is already plain text, changing the extension usually preserves the stylesheet source while making it available to software that does not recognize .css.

What CSS is

CSS (Cascading Style Sheets) is a plain-text stylesheet language used mainly with HTML documents. It defines presentation and layout through selectors, declarations, at-rules, comments, media queries, custom properties, and imported resources such as fonts or other stylesheets.

Web developers write CSS in Visual Studio Code, Sublime Text, Notepad++, TextEdit, and other code editors. Browsers normally load files such as style.css when an HTML document references them as stylesheets. Renaming the file to .txt removes the conventional CSS association and may stop automatic stylesheet loading until the file is renamed back and referenced correctly.

What TXT is

TXT is a generic plain-text file type with no required syntax, layout model, styling, or application-specific metadata. It can be opened by text editors, command-line tools, document-management systems, code repositories, and most operating systems.

A TXT copy is suitable for reviewing or archiving CSS source, submitting it to a system that accepts only plain-text files, or storing it in a general-purpose text collection. It does not retain editor features such as syntax highlighting, code folding, formatting profiles, or project associations. TXT also does not define a single mandatory character encoding, so the chosen encoding must be preserved when non-ASCII characters are present.

How to convert CSS to TXT

Rename the file without changing its contents

Renaming is the most exact method when the CSS is already plain text and no encoding conversion is required.

1. Make a backup of the original .css file.
2. On Windows, enable View → Show → File name extensions in File Explorer.
3. Rename the file, for example from style.css to style.txt, and confirm the extension change.
4. On macOS Finder, select the file, press Return, and replace .css with .txt. In a terminal, run mv style.css style.txt.
5. In Windows PowerShell, run Rename-Item style.css style.txt.

Renaming does not alter the CSS text, line endings, or character encoding. Check that the result is not an accidental double extension such as style.txt.css.

Save a copy from a text editor

1. Open the CSS file in Notepad, Notepad++, Visual Studio Code, Sublime Text, or TextEdit set to plain-text mode.
2. Choose File → Save As.
3. Enter a new filename ending in .txt, such as style.txt.
4. Select UTF-8 when the editor provides an encoding option. In Windows Notepad, select All files for Save as type to prevent an unwanted extra extension.
5. Save the new file and keep the original .css file unchanged.

This method can change encoding, line endings, or an editor-inserted byte-order mark, depending on the settings. Review the saved file if exact source preservation matters.

Use the built-in converter

You can convert the file on 101convert.com for free without installing software: upload the CSS file, choose TXT as the output format, start the conversion, and download the result. For confidential stylesheets, prefer local renaming or saving because an upload sends the file to a remote service.

Quality and compatibility limits

This is normally an extension or container change, not a language translation. Selectors, rules, comments, variables, media queries, minified code, and CSS strings remain text; the conversion does not render the stylesheet or validate its syntax.

Preserve UTF-8 when the file contains accented characters, non-Latin text, symbols, or escaped content. An incompatible encoding can corrupt comments, string values, or custom property values. A TXT file is not automatically usable as a stylesheet: rename it back to .css, ensure its contents are valid CSS, and reference it correctly from the HTML document before using it in a browser.
