What Is Zalgo Text?
Zalgo text is a style of internet text that appears corrupted, glitchy, or possessed — with characters that seem to bleed upward and downward off the line, overlapping with surrounding text. The name comes from an internet horror meme character called Zalgo, popularized in creepypasta communities around 2004, whose appearances were always accompanied by distorted imagery and text.
Despite looking like a technical glitch or broken encoding, Zalgo text is entirely valid Unicode. It is deliberately constructed using real characters stacked on top of each other. When you paste Zalgo text into any modern text field — Discord, Twitter, Instagram, a word processor — it renders the same way because all the characters involved are standard Unicode.
The effect ranges from subtle (a few marks above and below each letter) to extreme (hundreds of stacked characters that completely obscure the original text and extend far above and below the baseline). Most Zalgo text generators let you control the intensity level.
How Zalgo Text Works
Standard Unicode text is written left to right (or right to left for Arabic and Hebrew), with each character occupying its own horizontal space. But Unicode also includes a special category of characters called combining characters — diacritics and marks that attach visually to the preceding character rather than occupying their own space. Accents like é, ñ, and ü are created using combining characters. Zalgo text works by stacking hundreds of these combining characters above (using Unicode combining marks above, U+0300–U+036F) and below (using combining marks below) each regular letter.
The result is that a single letter like "A" might actually be the character U+0041 followed by 50 to 200 combining characters, all rendering as marks clustered around that one letter. The text is still technically readable — the base characters are there — but the sheer density of combining marks makes it visually overwhelming and creates the glitch aesthetic.
Examples of Zalgo Text
- Mild: Z̃ȧl̀g̀ő (a few combining marks above each letter)
- Medium: Z̴̧a̵͔l̴͓g̴͉o̵͙ (multiple combining marks, visible glitch effect)

- Used in meme captions, horror forum posts, and ARG (alternate reality game) content to create an "ominous" or corrupted-data aesthetic
