How to Send a Blank Message on WhatsApp
Try it yourself: open any WhatsApp chat, tap the space bar a few times, and watch the send button. Nothing happens. WhatsApp will not send an empty message — not a blank one, not a spaces-only one, not one made of new lines. As far as the app is concerned, a message with nothing in it is no message at all — there is nothing to send.
There is, however, a character that looks like nothing while still counting as something. Paste one invisible character into the message box and WhatsApp happily sends it; the bubble that arrives on the other side is completely, perfectly blank. This guide walks through the whole trick — why it works, the exact steps on Android, iPhone and WhatsApp Web, and what to do when it does not work first time.
Why WhatsApp Won't Send an Empty Message
A message made only of ordinary spaces and line breaks counts as empty in WhatsApp: if that is all the message box holds, the send button stays inactive and nothing leaves your phone. The effect is a sensible one — it stops people firing off messages that contain nothing but accidental taps.
The invisible character gets around this because of what it is. The Hangul Filler is a real letter in the Unicode standard — a placeholder used in Korean text — not a space and not whitespace. So a message whose entire content is one Hangul Filler is, as far as the app is concerned, a one-letter message. It sends, it delivers, and it renders as nothing at all.
Step by Step on Android
- Tap the copy button in the box above. If you are reading this on a computer, open this page on your phone instead — the character needs to be on the phone's clipboard.
- Open WhatsApp and go into the chat you want to send the blank message to.
- Tap the message box, then long-press it and choose Paste. Nothing visible appears — that is correct. The box is not empty; it holds one invisible character.
- Tap the send button, which is now active.
- An empty message bubble appears in the chat. That is the whole trick.
Step by Step on iPhone
- Tap the copy button in the box above while reading this page on your iPhone.
- Open WhatsApp and enter the chat.
- Tap the message field, then tap it again (or long-press) and choose Paste from the small menu that appears.
- The field still looks empty, but the send arrow is now available — tap it.
- Your contact receives a blank bubble, timestamp and all.
Step by Step on WhatsApp Web or Desktop
- Click the copy button in the box above.
- Open WhatsApp Web or the desktop app and click into the chat.
- Click the message box and press Ctrl+V (on a Mac, Cmd+V) to paste.
- Press Enter. The blank message sends just as it does from a phone.
Which Character Should You Use?
Not every invisible character behaves the same way. These are the five from our Invisible Character tool, with what each one actually does:
| Character | Code | Sends on WhatsApp? | Good for |
|---|---|---|---|
| Hangul Filler | U+3164 | Yes — the reliable pick | Blank messages, blank About line |
| Halfwidth Hangul Filler | U+FFA0 | Yes | Blank messages |
| Braille Pattern Blank | U+2800 | Usually yes | Blank comments, display names, bios |
| Zero Width Space | U+200B | Not on its own | Breaks inside bios and captions |
| No-Break Space | U+00A0 | No — behaves like a space | Keeping two words on one line |
Start with the Hangul Filler — it is the one the steps above are built on. Keep the Braille Pattern Blank in mind as the fallback: it behaves like an ordinary symbol rather than anything space-like, so it often works in places where the others do not.
More Places a Blank Character Works
A blank WhatsApp About line
The same paste works in your profile. Open WhatsApp, tap your profile photo, tap the About line, clear whatever is written there, paste the Hangul Filler and save. Anyone viewing your profile sees an About section with nothing in it.
Blank comments on Instagram, Facebook and YouTube
Most social apps refuse a completely empty comment too, and the Braille Pattern Blank (U+2800) is the character that most often gets through — it has real width, so it counts as content. Copy it from the tool page, paste it into the comment box and post.
Blank display names and bios
Some games and apps accept a display name built from the Braille Pattern Blank, which displays as no name at all. And a Zero Width Space placed on its own line can hold a gap open in a bio or caption where the app would otherwise squash empty lines together.
Troubleshooting
The send button still does nothing
Almost certainly, what you pasted was not the character. If you copied from somewhere that turned it into a plain space — or if the paste simply did not happen — the box really is empty. Come back to this page, tap the copy button again, and paste straight into the WhatsApp message box without stopping in another app on the way.
The character vanished when I pasted
Some keyboards and note apps can strip invisible characters when text passes through them. Paste directly into WhatsApp rather than via an intermediate app. If a character keeps disappearing, switch to the Braille Pattern Blank (U+2800) from the tool page — a symbol tends to survive the trip better than a filler.
My friend sees a small empty box instead of a blank
On very old phones, the system font may not include the Hangul Filler glyph, so the recipient's phone draws an empty box outline where the character sits. The message still sent correctly — it is a font issue at their end. Trying the Halfwidth Hangul Filler (U+FFA0) or the Braille Pattern Blank (U+2800) is worthwhile, because different devices carry different glyphs.
Frequently Asked Questions
Why does WhatsApp say can't send an empty message?
Because a message made only of ordinary spaces counts as empty to WhatsApp, and a message with no content cannot be sent — the send button simply stays inactive. A message holding even one invisible character is different: a character is content even when it draws nothing, so it sends.
How do I make my WhatsApp about blank?
Copy the Hangul Filler (U+3164) from the box at the top of this guide, then open WhatsApp, tap your profile photo, tap your About line, delete what is there, paste the character and save. The About line then reads as empty, because the character occupying it is invisible.
Can I send invisible ink messages on WhatsApp?
WhatsApp has no invisible-ink feature like the one in Apple's Messages app — there is no effect that hides a message until the reader taps it. A blank message made with an invisible character is the closest equivalent: the bubble arrives looking empty.
Does this work on WhatsApp Web and Desktop?
Yes. The character is ordinary text, and the same copy-and-paste trick works in WhatsApp Web and the desktop app: copy it, paste it into the message box with Ctrl+V (Cmd+V on a Mac) and press Enter.
Is sending a blank message against WhatsApp's rules?
The message is an ordinary Unicode character sent through the normal app — nothing is hacked, modified or automated. As with any message, sending blanks in bulk to people who do not want them could be reported as spam, so keep the joke among friends.
The Short Version
WhatsApp will not send a message made only of spaces — spaces alone count as empty. One Hangul Filler character — copied from the box at the top of this page — is real content, so the message sends and arrives looking completely blank. The same character empties your About line, and its cousin the Braille Pattern Blank handles blank comments and names elsewhere. When you need more than one character, or a long run of blank text, the Invisible Character tool generates up to 1,000 at a time.
