Classified Text Generator: Black Out Words

How the blackout works

Each letter or digit you type is replaced by a full block, the solid rectangle at U+2588. Spaces, punctuation and emoji stay exactly where they were, so the message keeps its outline. A letter with accents counts as one character and becomes one block: “Tiếng Việt” turns into █████ ████.

That outline is the fun part. Readers can see how many words you hid and roughly how long each one is, which makes classified text perfect for teasers, guessing games and the classic redacted-document meme.

Looks like a secret, isn’t a safe

The blocks carry no trace of the original letters, so classified text cannot be turned back into what you typed, by this site or anyone else. That one-way change feels secure, but the shape of the message still leaks information: word lengths, the number of digits, punctuation and line breaks. A four-block PIN is still a four-digit PIN.

Treat it as a visual joke rather than a privacy tool. To protect a password, address or account number, leave it out of the post entirely. Screen readers may also read each block aloud, which gets tiresome fast.

Ideas for using it

Hide the punchline of a joke, tease a product name before launch, post a “declassified” list where only one line is readable, or black out a single word in a caption for drama: convert just that word and paste the blocks between the plain parts. For a softer look where the words stay legible, try strikethrough text.
