How to use the Zalgo text generator
- Type or paste text in the Normal text box. The Zalgo version appears as you type.
- Choose an Intensity: Mild adds a few marks, Medium is the classic glitch look, and Max piles marks high above and below the line.
- Pick where the marks go: Above, Through (strike-through overlays) or Below the letters.
- Press Copy to paste it anywhere, or Shuffle for a different random mix.
To clean up Zalgo text, press the arrows between the two labels and paste it into the box.
Where Zalgo text comes from
Zalgo started on the Something Awful forums in 2004, when users edited innocent comic strips so the characters were corrupted by an unseen being called Zalgo, with bleeding eyes and the line "He comes". As the meme spread, people found they could make text look possessed the same way by stacking Unicode combining marks, and the glitchy text took the Zalgo name.
How combining marks make text glitch
Unicode separates letters from the marks that can sit on them. The acute accent in é can be stored as an e followed by a combining acute accent, a character that has no width of its own and is drawn on top of the letter before it. Nothing stops a text from adding a second, a third or a fiftieth mark, and text engines draw every one, stacking each a little higher or lower.
This generator picks from about a hundred marks in the Combining Diacritical Marks block, U+0300 to U+036F:
- Above: accents, tildes, rings and small letters drawn over the letter.
- Through: overlay strokes and slashes, U+0334 to U+0338, drawn across the letter.
- Below: dots, rings, bridges and lines drawn under the letter.
Because the marks spill into the space around the text, Zalgo text can cover the line above or below it. Many apps clip it at the edge of a message or a name.
Tips for using glitch text
- Usernames and bios: Mild works best. Many sites limit the number of characters, and every mark counts as one.
- Spooky posts and Halloween: Medium gives the classic look without hiding the words.
- Memes: Max is unreadable on purpose, so keep the message short.
- Important text: do not glitch it. Search engines, screen readers and some apps struggle with it.
