Strikethrough, underline, and bold text are formatting styles that make digital text stand out by altering its visual weight or structure. You can generate all three styles online using Unicode-based formatting tools that convert plain text into styled characters you can copy and paste anywhere—bios, captions, documents, Discord, Instagram, TikTok, Google Docs, and more.
This guide explains what each formatting style means, how they work, why online tools can generate them instantly, and how you can use them across different platforms.
What Is Underline Text?
Underline text is typed content displayed with a line underneath each character. In digital communication, underline formatting is used for emphasis, organization, hyperlinking, and stylistic decoration.
Online tools generate underline text using:
- Unicode combining characters, which sit beneath each letter
- Decorative underline symbols, such as low lines and aesthetic dividers
- Extended underline character sets, which create script-style or stylized underlines
Underline formatting works in usernames, bios, captions, chat apps, and documents because Unicode characters are supported across all major platforms.
What Is Strikethrough Text?
Strikethrough text appears with a horizontal line drawn through the center of each character. It communicates correction, irony, humor, or intentional visual styling.
Online strikethrough generators do this by applying:
- Unicode overlay characters, which place a strike bar through text
- Tilde-style strikethrough symbols, for aesthetic variations
- Double-strikethrough Unicode marks, used in stylized typography
Since these are Unicode-based, you can copy and paste strikethrough text into social media bios, captions, Discord messages, and documents without losing formatting.
How Do Online Text Formatting Tools Work?
Online formatting tools transform plain text into styled text using three methods:
1. Unicode Character Mapping
Each letter is replaced with a bold, italic, or script Unicode equivalent.
Example:A → 𝐀 (bold)b → 𝒃 (italic script)
2. Combining Characters
These add effects (underline, strikethrough) on top of existing text.
Example:a̲ (underlined)t̶ (strikethrough)
3. HTML/CSS Wrapping (For Web)
Used for blog posts, websites, and editors that support markup:
<b>Bold</b><u>Underline</u><s>Strikethrough</s>
Unicode formats are preferred for Instagram, TikTok, Discord, and messaging apps because they work universally and require no HTML support.
How to Make Strikethrough Text Online
Strikethrough text online is created by converting plain characters into Unicode characters that contain a strike bar running through them. This allows you to paste strikethrough text on Instagram, TikTok, Discord, or any platform that supports basic Unicode.
Steps to generate strikethrough text online
- Visit a strikethrough text generator tool on TextToolz.
- Enter the text you want to style.
- Choose a strikethrough format (single, double, or aesthetic variations).
- Copy the styled output.
- Paste it into your bio, caption, username, or message.
Strikethrough text is widely used to show edits, humor, sarcasm, aesthetic styling, or crossed-out phrases for effect.
How to Make Underline Text Online
Underline text is created using Unicode combining underline marks or decorative underline characters that appear beneath each letter.
Steps to generate underline text online
- Open an online underline text generator tool on TextToolz.com.
- Type the text you want to underline.
- Select a style (single underline, double underline, dotted underline, aesthetic underline).
- Copy the formatted result.
- Paste it into any app that supports Unicode.
Underline text is especially popular for Instagram bios, TikTok captions, fanpage headers, and aesthetic layouts.
How to Make Bold Text Online
Bold text online uses special Unicode characters that mimic bold typography. These characters visually appear heavier and stand out more than normal text.
Steps to generate bold text online
- Visit an online bold text generator tool.
- Enter your text into the input field.
- Choose from bold serif, bold sans, or aesthetic bold styles.
- Copy the bold Unicode version of your text.
- Paste it into your social media profile or document.
Bold text increases emphasis, readability, and stylistic impact—making it useful for names, headings, bios, and standout lines in captions.
How to Copy and Use These Formats on Instagram, TikTok, Discord & More
Bold, underline, and strikethrough text can be copied directly from online generators and pasted into most social platforms. Because the formatting is produced using Unicode characters instead of HTML, the styles remain intact across apps.
Where you can paste styled text
- Instagram: bios, captions, comments, story text
- TikTok: bios, usernames, captions, replies
- Discord: nicknames, channel names, chat messages, server roles
- Twitter/X: display names, tweets, replies
- YouTube: descriptions, comments
- Facebook: statuses, comments
- WhatsApp: statuses & DMs
Formatting helps highlight important words, create aesthetic profiles, or add emphasis.
