You can’t actually “copy and paste nothing” into a Roblox message in a way that sends an invisible/blank message, because Roblox chat blocks empty or mostly empty messages. What people usually mean by this is:

  1. Sending a message that looks blank (invisible text / blank name style), or
  2. Just copying and pasting normal text into Roblox chat.

Below is how both work, and why “nothing” won’t go through.

Quick answer

  • Roblox does not allow blank chat messages. If you try to send “nothing,” the chat will just not send it.
  • To paste something into Roblox chat:
    • PC/Mac: Highlight text → Ctrl+C (or Cmd+C) → click chat box → Ctrl+V (or Cmd+V).
    • Mobile: Long‑press text → select → “Copy” → long‑press chat box → “Paste”.

If your goal is a message that appears empty, you’d need special Unicode characters (like blank/display‑invisible characters), but Roblox often filters or replaces those, so it’s unreliable and can get flagged as spam.

How to copy and paste normal text into Roblox chat

On PC (Windows)

  1. Open Roblox and enter a game.
  2. Press / or click the chat icon to open the chat box.
  3. In any text field (outside Roblox, like Notepad, a website, Discord, etc.):
    • Highlight the text you want.
    • Press Ctrl+C to copy.
  4. Click inside the Roblox chat box.
  5. Press Ctrl+V to paste.
  6. Press Enter to send.

On Mac

Same steps, but use:

  • Cmd+C to copy
  • Cmd+V to paste.

On Mobile (iOS / Android)

  1. Open the game and tap the chat button.
  2. To copy:
    • In another app or text field, long‑press the text.
    • Drag the selection handles to choose what you want.
    • Tap Copy.
  3. To paste:
    • Long‑press inside the Roblox chat input.
    • Tap Paste if it appears.

Note: Some mobile versions of Roblox have limited copy/paste support for chat; if it doesn’t work, try the PC version or a different app for copying first.

Why you can’t “paste nothing”

Roblox chat validates messages before sending:

  • If the message is empty or only whitespace, it’s blocked.
  • If the message is too short or looks like spam (e.g., repeated invisible characters), it may be filtered or rejected.

So even if you “copy” a blank space or some invisible character, Roblox will often just not send it, or it will show as a placeholder (like a space or nothing) that other players might not see as a real message. In other words:

  • Copying : You can copy empty text or invisible characters from somewhere.
  • Pasting into Roblox chat : You can paste them, but sending them as a message will usually fail or be filtered.

If you meant “invisible/blank name style”

Some sites let you copy special Unicode characters (like ㅤ, ⠀, ᠎) to make usernames or text that look blank. You can:

  1. Go to a site that offers “invisible text” or “blank display text.”
  2. Copy the character.
  3. Paste it into Roblox chat using the methods above.

But:

  • Roblox may replace these with normal spaces or block them.
  • Using them repeatedly can be treated as spam or inappropriate behavior.

So while you can technically paste invisible characters, sending them as a “message with nothing” is not reliably supported.

Summary

  • You can copy and paste regular text into Roblox messages using Ctrl/Cmd+C and Ctrl/Cmd+V (or mobile long‑press copy/paste).
  • You cannot reliably send a message that is truly “nothing”; Roblox blocks empty messages.
  • “Invisible” text tricks exist but are inconsistent and may be filtered or flagged.
