How to Underline in WhatsApp: 3 Methods That Work (2026)

Overview: WhatsApp does not have a native underline button. Unlike bold (*text*), italic (_text_), and strikethrough (~text~), underline has no built-in shortcut in WhatsApp's formatting system. There are three reliable workarounds: using a Unicode underline text generator (the fastest method), adding the Unicode combining character manually, or sending the underlined text as an image. This guide covers all three methods with exact steps for Android, iPhone, and WhatsApp Web.

For businesses sending formatted messages to a full contact list, a WhatsApp bulk message sender free tool handles those outbound sends. This guide focuses on the underline workarounds for personal and business WhatsApp messages.

If your phone's keyboard shows an underline option when you select text in WhatsApp, this comes from the keyboard app, not from WhatsApp. WhatsApp does not apply the underline even if the keyboard sends it, the text arrives without underline formatting on the recipient's screen.

WhatsApp supports a range of text formatting options through simple shortcuts. How to highlight text in WhatsApp covers the full formatting system including the toolbar method and keyboard shortcuts. Here is where underline stands among all the options:

Underline is the only standard text formatting style that has no WhatsApp shortcut. The three methods below create the visual appearance of underlined text through workarounds.

Method 1: Unicode Underline Text Generator (Recommended)

This is the fastest and most practical method. Unicode underline generators are free websites that add a Unicode combining character (U+0332, called Combining Low Line) after each letter. This creates an underline effect that WhatsApp displays exactly as typed.

• Open any browser and search for "underline text generator" or go to a site like yaytext.com, lingojam.com, or unicode-generator.de.
• Type the word or phrase you want to underline into the input box.
• Find the underline style in the output options. The result looks like: H̲e̲l̲l̲o̲ (each letter has a line below it).
• Select and copy the underlined text from the output.
• Open WhatsApp and paste the underlined text into the message field.
• Send the message. The underline effect appears on both Android and iPhone.

Method 2: Manual Unicode (Advanced)

This method produces the same result as Method 1 but without using a website. It works by adding the Unicode character U+0332 (Combining Low Line) after each letter manually. This is useful when you cannot access a generator website.

How to type U+0332 on Android: Some keyboards support Unicode input through long-press. Otherwise, use a dedicated Unicode keyboard app or input method. The character must be inserted after each letter individually, it is not a shortcut for whole words.

How to type U+0332 on iPhone: Go to Settings > General > Keyboard > Text Replacement. Add a shortcut where the phrase is U+0332 displayed as the combining character. A simpler route is to copy the character from a Unicode reference site and paste it after each letter.

Practical recommendation: For most users, Method 1 (generator website) is far faster. Manual Unicode input is only worth the effort for single short words where you need to avoid third-party sites.

Method 3: Send as an Image (Most Consistent)

If you need the underline to look exactly right on every device, for business announcements, formal communications, or branded content, create the underlined text as an image and send it as a photo or document.

• Open any app that supports underline formatting: Google Docs, Microsoft Word, Canva, the iPhone Notes app, or Samsung Notes.
• Type your text and apply underline formatting using the app's native underline button (U with a line).
• Screenshot the underlined text. Crop tightly to the text area if needed.
• Open WhatsApp, go to the chat, tap the attachment icon, and send the screenshot as a photo or document.
• For best quality, send as a document (not as a compressed photo) to avoid image quality loss.

Use Method 1 (generator) for the fastest result on Android:

• Open Chrome on your Android phone and go to yaytext.com or any underline generator.
• Type your text and copy the underlined output.
• Switch to WhatsApp and open the target chat.
• Long-press the message field and tap Paste.
• The underlined Unicode text appears in the message field. Tap Send.

To use Method 3 (image) on Android: type the text in Samsung Notes or Google Keep with underline, screenshot it, and send it from WhatsApp via the attachment icon.

On iPhone, the Unicode generator method works the same way:

• Open Safari and go to an underline text generator website.
• Type the text you want underlined and copy the output.
• Open WhatsApp and go to your chat.
• Long-press the message field and tap Paste.
• Review the underlined text and tap the send arrow.

For Method 3 (image) on iPhone: use the Notes app with underline turned on (tap the underline icon in the Notes formatting toolbar), type your text, screenshot it, and send from WhatsApp.

WhatsApp Web is often the easiest environment for this workaround because you can have the generator and WhatsApp Web open in two browser tabs:

• In your browser, open a new tab and go to an underline text generator.
• Type your text and copy the underlined result.
• Switch back to your WhatsApp Web tab.
• Click in the message field and press Ctrl+V (Windows) or Cmd+V (Mac) to paste.
• Review and press Enter to send.

On WhatsApp Web and Desktop you can also use the built-in formatting toolbar: select text you have typed, right-click or look for the formatting icons (B, I, S) that appear above the message field. Underline is not in this toolbar, confirming it is not natively supported.

WhatsApp Status supports both text and image formats. For underlined text in a Status:

Option 1 - Unicode text Status: Generate underlined text using the generator method, copy it, and paste it directly into the WhatsApp Status text box. Test how it appears on your preview before posting.

Option 2 - Image Status: Create your Status design in Canva, Google Slides, or any design app with underline applied, screenshot or export the image, and post it as a photo Status. This produces the most visually consistent result.

For business messaging, especially broadcast campaigns and template messages, underline workarounds are often not the best approach. WhatsApp message templates for business covers the structured formatting options available in WhatsApp templates, where bold headings and bulleted lists typically produce better results than Unicode underline.

A cleaner emphasis structure that consistently outperforms Unicode underline for business use:

This combination covers every emphasis need a business message typically requires, with native formatting that renders identically on every device.

WhatsApp does not have a native underline button. The three workarounds that produce an underline effect are: a Unicode underline text generator (fastest, paste directly into WhatsApp), manual Unicode insertion (no website required, more effort), and sending underlined text as an image (most visually consistent, best for business).

For quick personal messages, the generator method works well. For business messages where consistent rendering matters, the image method is more reliable. For all business text formatting needs, bold, lists, block quotes, WhatsApp's built-in formatting options are always the cleaner choice over Unicode workarounds.
