About .gmi Files
GMI files are Gemini files that use the MIME type text/gemini. They hold plain text with minimal markup for the Gemini protocol.
- Purpose: They serve content on Gemini networks, where simplicity and security matter.
- Usage: They display text-based web pages with a lightweight markup system.
- Editing: You can open and edit these files with any simple text editor.
- Viewing: Specialized Gemini browsers like Lagrange, Amfora, and Moonlander render them correctly.
Based on information from FilExt.com, GMI files provide an alternative to traditional web formats by prioritizing minimalism and clean design.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is a .gmi file?
A .gmi file is a text document formatted in Gemtext, the native markup language of the Gemini protocol. It is similar to Markdown but much stricter and simpler, designed for lightweight, privacy-focused browsing. These files are served with the MIME type text/gemini.
How do I open a .gmi file?
You need a specialized Gemini browser to view these files as intended. Popular graphical clients include Lagrange and Kristall, while Amfora is a great option for terminal users. Since the file contains plain text, you can also open it in Notepad or TextEdit to view the raw source code.
Can I view .gmi files in Chrome, Firefox, or Edge?
Standard web browsers do not support the gemini:// protocol or render .gmi files natively. To view them in a regular browser, you must use an HTTP-to-Gemini proxy (like Portal or Mozz.us) or install a specific browser extension that adds Gemini support.
How do I create or edit a .gmi file?
You can create .gmi files using any basic text editor like Notepad++, VS Code, or Sublime Text. The syntax is minimal; for example, lines starting with # are headers, and lines starting with => represent links. Always save the document with UTF-8 encoding.
What is the correct MIME type for serving .gmi files?
The standard media type is text/gemini. If you are configuring a server, you must ensure the content type includes the charset parameter, specifically text/gemini; lang=en; charset=utf-8 (adjusting the language code as necessary), as UTF-8 is mandatory in the Gemini specification.
How can I convert a .gmi file to HTML?
Because Gemtext is simpler than HTML, conversion is straightforward using tools like gmi2html or various Python scripts available on GitHub. These tools parse the .gmi markup headers and links and translate them into standard HTML tags (<h1>, <a href>, etc.) for display on the traditional web.
Why are .gmi files used instead of .html?
The .gmi format prioritizes minimalism, removing inline images, scripts, and complex styling to ensure fast loading and user privacy. This reduces bloat and makes content easily readable on any device, from modern PCs to vintage hardware, without the tracking scripts often found in HTML files.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
