Copy a character
Tap any character above. Braille blank (U+2800) is the safer default for WhatsApp messages — it renders more reliably across Android, iOS, and Web than zero-width space.
Platform guide
Copy zero-width and braille blank characters for WhatsApp chats, the 139-character About field, status updates, and group names. Each one is tested against WhatsApp's actual field limits — including the 50-character cap on the new timed About.
WhatsApp rejects truly empty messages. Paste one zero-width or braille blank character and the message sends, showing up on the recipient's side as a blank bubble. The same trick works in the About field under your name, in text statuses, and in group names — every one of those fields has a hard cap, and invisible characters count against it. WhatsApp counts in UTF-16 code units, the same as JavaScript string length, so an emoji costs two units and a braille blank costs one. The About field gives you 139 characters (or roughly 50 in the new timed About rolling out since November 2025), the profile name 25, the group name 100. This page hands you the exact characters we tested in each WhatsApp field.
Tap any character above. Braille blank (U+2800) is the safer default for WhatsApp messages — it renders more reliably across Android, iOS, and Web than zero-width space.
Paste into a chat, the About field, a text status, or a group name. The profile name field is the one to avoid: it strips most special characters on save.
Long-press the message box, choose Paste, then send. The bubble posts empty to you and appears blank to the recipient — but WhatsApp still counts it as delivered content.
WhatsApp blocks empty messages. A single invisible character passes the check and arrives as an empty chat bubble — the recipient sees your name with blank content underneath.
The About field under your name gives you 139 characters with no paragraph-break control. Invisible characters fake a line break — just watch the cap.
Paste an invisible character into the 100-character group subject field and the group shows a blank name in the chat list. Only the first ~28 characters render in the list preview.
Text statuses cap at 700 characters. Use invisible characters to push a second line down or create gaps in a longer status update.
Send a blank message in a one-to-one or group chat. Each message can hold up to 65,536 characters, so invisible padding is effectively free.
Add a blank line inside the 139-character About, or set the new timed About (around 50 characters) to look empty when paired with an emoji.
Make a group subject appear blank. Stays inside the 100-character cap; the full name shows only when members open group info.
Push text onto a new line inside a 700-character text status. Status captions on photos and videos get 1,024 characters.
WhatsApp counts every invisible character as content — there is no field where an invisible glyph is free. The chat box is the most forgiving surface: 65,536 UTF-16 units of headroom means you can stack dozens of invisible characters and still send. The tight fields are the ones to plan around. About gives you 139 characters in its classic form, but WhatsApp began replacing that with a shorter timed About in November 2025 — the new field reportedly caps at around 50 characters, expires after anywhere from one hour to one month, and lives at the top of one-to-one chats, so invisible line-break tricks die with the expiry. The profile name (25 characters) strips most non-printing characters on save. Group descriptions, raised to 512 characters in a 2018 update, accept invisible Unicode freely. Emojis cost two UTF-16 units each, which matters fast in the short fields.
Chats (65,536 characters), the classic About (139), the new timed About (around 50, rolling out since November 2025), text statuses (700), status captions (1,024), group names (100), and group descriptions (512) all accept invisible Unicode characters. The profile name field (25 characters) is the hard exception — WhatsApp strips most non-printing characters there on save. WhatsApp counts characters as UTF-16 code units, so most zero-width and braille characters cost one unit and emojis cost two. Rendering is consistent across iOS, Android, WhatsApp Web, and WhatsApp Desktop; braille blank (U+2800) is the most reliably invisible across the surfaces we checked, while zero-width space (U+200B) occasionally gets stripped by older Android input methods.
Yes. WhatsApp blocks truly empty messages, but a single invisible character passes the check. The message arrives as an empty bubble with your name above it.
It works, but the field is shorter and it expires. The new About reportedly caps at around 50 characters (down from 139 in the classic field) and disappears after anywhere from one hour to one month, depending on the timer you pick.
Two likely causes. The group subject truncated at the list preview (~28 characters), or your keyboard stripped the invisible character on paste. Re-paste using braille blank (U+2800) and check the full group info screen.
Yes, but the limit is 65,536 characters per message. You will never hit it stacking invisible characters. The cap that actually bites is the About field at 139 characters.
Braille blank (U+2800). It renders consistently across iOS, Android, Web, and Desktop, while zero-width space (U+200B) gets stripped by some Android keyboards and older clients.
Invisible characters are standard Unicode and aren't called out in WhatsApp's terms. That said, spamming blank messages to harass or overwhelm someone can still get your account actioned. Use it for formatting, not abuse.
Pick braille blank if you're not sure, paste it into a chat or your About, and check how it renders on the recipient's device.
