Add Underline to Text

Map visible characters to U+0332 while preserving structural whitespace. Ensure formatting consistency across non-rich text environments and documentation.

Input Text

Paste the text you want to process.

Underlined text:

About This Tool

Add Underline to Text converts visible characters into underlined text in one step. It is useful for emphasis, stylized labels, social posts, and decorative text snippets.

How It Works

Use the tool in three simple steps:

Paste text - Add the text you want to underline.
Click Add Underline - Apply underlines to visible characters instantly.
Copy the result - Reuse the generated underlined text anywhere.

Basic Examples

Single word
```
Input:
Hello

Output:
H?e?l?l?o?
```

Two words

Input:
Bright day

Output:
B?r?i?g?h?t? d?a?y?

Real-World Usage Scenarios

Social Media Profile Customization - Professional Branding - Standard platforms like Instagram, X (Twitter), and LinkedIn do not provide native underlining tools for bios or display names. This tool generates Unicode-based styling that allows professionals to emphasize key credentials or contact details directly within their profile description.
Plain-Text Messaging - Emphasis without Rich Text - Communication tools like Slack, Discord, or standard SMS often lack granular text formatting options. By using underlined Unicode characters, users can highlight critical action items or deadlines in messages where Markdown or HTML tags are not supported.
Technical Documentation - Visual Anchors - In README files, code comments, or configuration logs that rely on plain text, underlining creates distinct visual hierarchies. Developers use these underlined strings to separate sections or emphasize specific variable names without breaking the text-only format.

Frequently Asked Questions

Is this equivalent to HTML underlining or CSS styles?

No. This tool uses Unicode combining characters (U+0332) to add a line below each letter. Unlike HTML tags or CSS 'text-decoration', this formatting is embedded into the text itself, making it portable across apps that do not support rich text.

Will the underlined text appear correctly on all devices?

Most modern operating systems (iOS, Android, Windows, macOS) and browsers support Unicode combining marks. However, some legacy systems or specific non-standard fonts may occasionally render the underline slightly offset.

Does this tool affect SEO or screen reader accessibility?

Unicode-styled text can be difficult for screen readers to interpret, as they may read each character individually. For SEO, search engines generally recognize the base characters, but it is recommended to use standard text for primary keywords.
