WhatsApp Blank
Message

WhatsApp does not document blank messages, and a browser cannot run WhatsApp for us to test, so treat this as a shortlist and not a promise. The three characters below are the ones third-party guides most often report as accepted, and each one is a real character rather than whitespace, which is why a plain trim does not strip it.

• Braille blank U+2800

  Try first. Unicode classes it as a symbol, not whitespace, so trimming does not remove it. Can show as a space-wide gap.

• Left-to-right mark U+200E

  Zero width, so it leaves no gap. Combine it with new lines for a taller message.

• Hangul filler U+3164

  A wide blank. A fallback if the first two are refused.

The zero width space (U+200B) is also suggested around the web, but some reports say it gets stripped, so it is not in the list. Ordinary spaces and empty messages are widely reported to be refused.

The steps are the same everywhere because you are only pasting text. Copy the result here, open the chat, tap into the message box and paste it the way you paste any text on that device, then tap send. On a computer, paste with Ctrl+V or Cmd+V in WhatsApp Web.

If the send button does not light up, or WhatsApp sends nothing, the character was probably rejected. Go back to the tool, pick the next one and try again. Because WhatsApp can change this without notice, a character that worked last month can stop working after an update.

A few things can go sideways, and most are about how a phone draws the character:

• A small box appears. The phone has no glyph for that character. Switch to a different one.
• The bubble is wider than expected. The Braille blank and Hangul filler have width. Use fewer, or use the left-to-right mark.
• Nothing changes when you add more. The left-to-right mark has no width. Tick the new line option to make the message taller.
• The other person sees something different. Their phone and app version draw it, not yours. Ask them if it matters.

Invisible characters also count as characters, and a screen reader may announce them, so they are a poor choice anywhere accessibility matters.

It is a small trick, best for fun and for layout: a playful reply with no words, a bubble that separates two parts of a conversation, or an invisible placeholder while you test how a chat looks. It is not a way to get attention, and sending lots of empty messages to someone who did not ask for them is likely to get you blocked.

The same idea keeps spacing in other places. Our Instagram line break generator puts an invisible character on blank lines so captions and bios keep their gaps, and our WhatsApp text formatter adds bold, italic and strikethrough to the messages you do write.
