Why use Fancy Underlines?
Attention Grabbing
A u̳n̳d̳e̳r̳l̳i̳n̳e̳d̳ word in a tweet or caption stops the scroll. Use it to highlight key points or calls to action.
Document Organization
Use different styles for headers vs sub-headers in plain text files. e.g. Double Line for Title, Single for H2.
How to Use

- Select: Choose from the 4 underline cards.
- Copy: Click Copy on the style you like.

Frequently Asked Questions
How does the text underlining work?
It uses Unicode 'combining characters' similar to how accents work. We attach a specific character (like a low line or dot) to every letter you type.
What underline styles are available?
We offer 4 styles: Single, Double, Wavy (Tilde), and Dotted underline.
Can I use Wavy Underline on Instagram?
Yes! The wavy underline uses a combining tilde below character (U+0330) which is supported by most social platforms like Instagram and Twitter.
Is there a strikethrough option?
We have moved the Strikethrough style to its own dedicated tool ('Add Strikethrough to Text') so this tool can focus purely on underlining options.
Can I convert a whole paragraph?
Yes, just paste your text. We recommend using Batch Mode for multiple lines to ensure the formatting stays clean.
Does Dotted Underline work everywhere?
Mostly yes, but some older fonts or devices might render the dots slightly off-center. It generally works well on modern mobile apps.
How do I remove the underline?
You can't just toggle it off. You need to delete the text and re-type it, or use a 'Clean Text' tool to remove the special characters.
Is it free?
Yes, completely free and unlimited usage.
Can I double underline numbers?
Yes, numbers work too! 1̳0̳0̳ looks great for emphasis.
What is the difference between single and double underline?
Single is a thin line (classic look). Double uses a special character that creates two thin parallel lines for stronger emphasis.
