.HANS file extension
To open .HANS files on Windows, right-click the .hans file → Open with → choose a text editor (for example, Notepad or another plain-text editor).
To open a .hans file, use any plain-text editor (for example, Notepad on Windows or TextEdit in plain-text mode on macOS). Because HANS is registered as a text format (text/vnd.hans), you generally do not need specialized software—just a monospaced view.

How to open .HANS files
Use these platform-specific instructions to open .HANS files safely.
Windows
- Right-click the .hans file → Open with → choose a text editor (for example, Notepad or another plain-text editor).
- If the art looks misaligned, switch to a monospaced font in the editor (for example, Consolas) and disable word wrap.
Mac
- Control-click the .hans file → Open With → choose TextEdit (or another text editor).
- In TextEdit, ensure it is in plain-text mode and use a monospaced font; also turn off line wrapping if possible.
Linux
- Open the .hans file with a text editor from your file manager (Open With → a text editor) or from the terminal with a text viewer.
- If the file type is not recognized automatically, ensure your desktop’s shared MIME database is up to date and open it as plain text.
iOS
- Open the file in the Files app and use a text-viewing app that can display monospaced text; if it renders poorly, transfer it to a desktop text editor for better control of font and wrapping.
Android
- Open the file with a text editor/viewer app and enable a monospaced font and no-wrapping view if available; otherwise transfer to a desktop for correct rendering.
Security notes
- A .hans file is a text format (7-bit ASCII art) and typically contains no active content like macros; the main risk is misleading content (for example, instructions or commands) rather than embedded execution.
- Be cautious when opening .hans files in tools that automatically interpret text (for example, terminal emulators that may react to escape sequences). If you suspect untrusted content, view it in a simple text editor that does not process control sequences.
- If a .hans file is unexpectedly large or causes a viewer to hang, treat it as untrusted input and open it in a minimal text viewer; text parsers can still have bugs even for plain-text formats.

OS-specific troubleshooting
What is a .HANS file?
.HANS corresponds to the IANA-registered media type text/vnd.hans. It is defined as 7-bit ASCII art, designed to be displayed with a monospaced font so alignment and drawings render correctly. Technically it is a text format, not a binary document container.
Background
HANS documents are a specialized kind of plain text: the content is ASCII art, where whitespace and fixed-width character alignment are essential to how the "document" looks. Unlike word-processing files, there is no embedded formatting, images, or layout engine—what you see depends on the font and line wrapping settings.
Because HANS is registered with IANA as text/vnd.hans and associated with the .hans extension, operating systems and applications that recognize MIME types can treat it as a text document. On Linux desktops, system-wide extension-to-MIME mapping commonly relies on the shared-mime-info database and related mechanisms defined by freedesktop.org.
In practice, .hans files are most commonly viewed or edited with text editors, terminal pagers, or browsers configured to show monospaced text. When the display is not monospaced (or lines are wrapped), the artwork can look "broken" even though the file is intact.
Common MIME types: text/vnd.hans

Common .HANS issues
ASCII art looks misaligned or "broken"
HANS content depends on fixed-width (monospaced) character display and consistent line breaks. Proportional fonts or word-wrapping will shift characters and ruin the alignment.
- Switch the viewer/editor to a monospaced font and increase the window width.
- Disable word wrap / line wrapping and ensure the file is shown as plain text.
The file opens as gibberish characters
A .hans file is defined as 7-bit ASCII art; if your app forces a different encoding or treats it as a different file type, characters may display incorrectly.
- Reopen the file in a plain-text editor and select an ASCII-compatible encoding if your editor offers encoding choices.
- Try a different text editor/viewer that allows explicit encoding selection.
Double-click opens the wrong app (or nothing happens)
Your system may not have an association set for .hans, even though it is a registered text media type. Desktop environments often rely on MIME databases for default handling.
- Use Open with and choose a text editor, then set it as the default for .hans if your OS offers that option.
- On Linux desktops, update/refresh MIME associations using your desktop’s shared MIME mechanisms (shared-mime-info).
FAQ
What program opens a .hans file?
Any plain-text editor can open it. For correct appearance, use a monospaced font and disable line wrapping.
Is .hans a Word or PDF document?
No. HANS is registered as a text format (text/vnd.hans) and is described as 7-bit ASCII art, not a binary word-processing or PDF format.
Why does it look different in different apps?
ASCII art depends on fixed-width fonts and consistent line breaks. Different apps may use proportional fonts, wrap lines, or change spacing, which alters the appearance.
Should I rename the file to .txt?
You usually do not need to. If your system does not recognize .hans, renaming to .txt can help some apps treat it as plain text, but it does not change the content; using Open with is typically better.
