To underline text in WhatsApp, generate underlined text with a Unicode underline generator, copy it, and paste it into your chat. WhatsApp has no built-in underline button, so this copy-and-paste method is the practical way to do it: each letter carries a combining mark (U+0332) that draws the line under it. It works on Android, iPhone, and WhatsApp Web.
This guide from Zyrro covers why there is no underline option, the steps on Android, iPhone, and WhatsApp Web, Status posts, bold combinations, and styles. No app install or account is needed.

Can you underline text in WhatsApp?
No. Underlined text in WhatsApp is ordinary text with a line under each letter, made with Unicode combining marks, because WhatsApp offers no underline formatting. The line travels with the characters, so it survives copy and paste.
Four built-in formats exist. Underline is missing.
| Format | How to apply it | Available |
|---|---|---|
| Bold | *text* | Yes |
| Italic | _text_ | Yes |
| Strikethrough | ~text~ | Yes |
| Monospace | “`text“` | Yes |
| Underline | No symbol, button, or shortcut | No |
Why can you not underline text in WhatsApp directly?
WhatsApp has never added underline to its formatting list. The formatting menu offers bold, italic, strikethrough, and monospace, and nothing else. No setting adds an underline option.
Important: do not trust guides that tell you to wrap text in underscores to underline it. In WhatsApp, _text_ makes the text italic, not underlined. Double underscores are no better: __text__ is the syntax for underline text in Discord, and it does not underline in WhatsApp. Your message arrives italic, or with visible underscores, and never underlined.
A wavy line under a word as you type is your keyboard spellchecker flagging a possible spelling mistake. Only you can see it, it disappears when you send the message, and the recipient never sees it. It is not formatting, and it is not the underline this guide creates.
How do you underline text in WhatsApp with a generator?
An underline generator adds a combining low line (U+0332) after every letter. The mark draws a line under the letter before it, and because it is part of the text, WhatsApp sends it unchanged. Follow these steps:
- Open the Underline Text Generator in your phone or computer browser.
- Type or paste the word or short phrase you want underlined. The styles update as you type.
- Tap Copy on the Single Underline style, or tap the underlined output itself.
- Paste it into the WhatsApp chat and check the line sits under every letter.
- Tap Send. The recipient sees the underlined text on Android, iPhone, and WhatsApp Web.
For example, “hello” becomes h̲e̲l̲l̲o̲ with Single Underline. Keep the underlined part short: one word, a name, or a short phrase reads clearly, while a whole underlined paragraph is hard to read.
Tip: paste straight into WhatsApp. Pasting into a plain-text note app first can strip the combining marks.

How do you underline text in WhatsApp on Android?
On Android, use the same generator method: there is no underline option in the text-selection menu and no keyboard shortcut for it. Open the generator in your browser, tap Copy on Single Underline, then long-press the WhatsApp message box, tap Paste, check the preview, and send.
The result does not depend on your Android version or keyboard app, because the underline is carried by the characters, not the phone. If the line looks broken on your screen, with small gaps between letters, check what the recipient sees: some Android fonts draw combining marks slightly lower, but the text usually arrives intact.
How do you underline text in WhatsApp on iPhone?
On iPhone, the process is identical: the text-selection menu offers bold, italic, strikethrough, and monospace, but no underline. Open the generator in Safari, tap Copy on Single Underline, then tap the WhatsApp message box, tap Paste, and send.
Do not confuse this with iMessage, where you can select text and tap Underline. That option belongs to iMessage only and does not work in WhatsApp, and no iPhone setting turns on underline for WhatsApp.
How do you underline text in WhatsApp Web?
On WhatsApp Web, copy the Single Underline style from a generator in another tab, click the WhatsApp Web message box, and paste with Ctrl+V (Windows) or Cmd+V (Mac).
There is no WhatsApp Web underline shortcut. Do not press Ctrl+U: in most browsers, including Chrome, it opens the page source view and never formats your message.
How do you underline text in a WhatsApp Status?
Paste generated underlined text into a text Status: create the Status, paste the copied word or phrase into the text field, and post it. The underline is part of the characters, so it shows as in a chat.
Keep Status text very short: viewers have only a few seconds, and one underlined word works best. The same method works for photo and video Status captions, whose drawing tools add no real underline to typed text.

How do you make text bold and underlined in WhatsApp?
Combine the two methods: generate the underlined text first, then wrap it in asterisks, which is WhatsApp’s bold symbol. The asterisks bold the whole string, and the combining marks keep the line under each letter. For bold on its own, see how to make text bold in WhatsApp.
| Effect | What to type or paste |
|---|---|
| Underline only | Paste generated underlined text |
| Bold and underline | *underlined text* |
| Italic and underline | _underlined text_ |
| Strikethrough and underline | ~underlined text~ |
Put the symbol next to the first and last underlined letters with no space. A space after the opening asterisk, such as * word*, breaks the bold formatting. If the effect does not appear, check the symbols, then send the underlined text alone.
Which underline style should you choose?
Start with Single Underline. It is the clearest style and renders most reliably on Android, iPhone, and WhatsApp Web. Other styles suit headings and playful messages more than everyday emphasis.
| Style | Unicode mark | Best for |
|---|---|---|
| Single Underline | U+0332 | Everyday emphasis, names, key words |
| Double Underline | U+0333 | Titles and key terms |
| Triple Underline | U+0332 plus U+0333 | Headings only |
| Wavy Underline | U+0330 | Playful messages |
| Dotted Underline | U+0323 | Subtle emphasis on short words |
| Dash Underline | U+0331 | Headings and labels |
For example, “hello” in Double Underline looks like h̳e̳l̳l̳o̳. All six styles, plus nine more, are in the Underline Text Generator, which offers 15 styles in total. Preview a style before sending it to a group: wavy and dotted styles can look faint on older phones.
How do you underline text in WhatsApp without a generator?
It is possible, but slow and error-prone: place the combining low line (U+0332) after every letter. Miss one and the line has a gap. Phone keyboards have no U+0332 key, so you must copy the mark once, then paste it after each letter by hand: eight pastes for a four-letter word.
The generator is faster: it adds the mark after every letter, including spaces, in one copy. If you try it manually, check every letter first, and use the Underline Text Generator if any line is missing. No shortcut or setting does the job faster.
Why is your underlined text not working?
Most failures have a small set of causes. Work through the table in order.
| What you see | Likely cause | Fix |
|---|---|---|
| Text arrives italic | _text_ means italic in WhatsApp | Use the generator, not underscores |
| Visible underscores | __text__ is Discord syntax | Paste generated underlined text |
| Gaps in the underline | A letter missed its mark | Copy again and paste once more |
| Small boxes, not letters | Phone font lacks the mark | Use Single Underline (U+0332) |
| Underline lost after editing | Editing can drop combining marks | Paste a fresh copy; do not edit inside it |
| Search cannot find the word | Underlined letters differ from plain letters | Keep searchable words in plain text |
Each underlined letter is a letter plus a mark, so underlined text can count as roughly twice as many characters in some counters, and screen readers may announce the marks awkwardly. Underline short phrases only.
Is underlined text safe to send in WhatsApp?
Yes. The marks are standard Unicode characters. They need no app install, keyboard permission, or account access, and they cannot change your WhatsApp settings.
Avoid third-party underline apps that ask for keyboard access or broad permissions a text tool does not need. A browser generator needing no install or sign-in is safer. Use underline sparingly: emphasis works because it is rare. Save it for a name, a date, or a warning.
Frequently Asked Questions
Can you underline text in WhatsApp without installing an app?
Yes. Open a Unicode underline generator in your browser, type your word, copy the Single Underline style, and paste it into WhatsApp. No app install, keyboard, or account is needed. The combining low line character (U+0332) after each letter draws the underline, and the result works on Android, iPhone, and WhatsApp Web.
How do you underline text in WhatsApp on Android?
On Android, open an underline generator in your browser, type your text, and tap Copy on the Single Underline style. Then open WhatsApp, long-press the message box, tap Paste, and send. There is no underline button in the WhatsApp text-selection menu on Android, so the copy-and-paste generator method is the way to do it.
How do you underline text in WhatsApp on iPhone?
On iPhone, open an underline generator in Safari, type your text, and tap Copy on the Single Underline style. Then open WhatsApp, tap the message box, tap Paste, and send. The iPhone format menu in WhatsApp offers bold, italic, strikethrough, and monospace, but no underline, and the iMessage underline option does not work in WhatsApp.
Is there a WhatsApp underline shortcut?
No, there is no WhatsApp underline shortcut. No symbol, keyboard shortcut, or setting underlines text in WhatsApp, and Ctrl+U does not work: in most browsers it opens the page source instead. The reliable method is to generate underlined text with a Unicode generator, copy it, and paste it into your chat, Status, or group description.
Can you highlight text in WhatsApp?
No, WhatsApp has no built-in text highlight or background colour option either. Bold, italic, strikethrough, and monospace are the only built-in formats. For emphasis, use bold with asterisks, or underline with a Unicode generator. Some keyboards offer coloured text through Unicode styled characters, but that changes the characters themselves, not a highlight behind them.
Why does WhatsApp underline some words while I type?
That wavy underline comes from your keyboard spellchecker, not from WhatsApp formatting. It flags a word the spellchecker thinks may be misspelled, and only you can see it while you type. It disappears when you send the message, and the recipient never sees it. To create a real underline that others see, use the generator method in this guide.
Does underlined text work in WhatsApp Status, groups, and WhatsApp Web?
Yes. Underlined text made with Unicode combining marks works in chats, group chats, text Status posts, captions, and WhatsApp Web, because the underline is part of the characters. Paste the generated text into the Status field or chat box as usual. Keep it short in Status posts, where viewers have only a few seconds to read.
Underlining takes one extra step — generate, copy, paste, send — because WhatsApp never added the option. Use Single Underline and save it for the word that matters. Find more WhatsApp text tricks and free tools from Zyrro.
