"Zalgo text" is the internet meme style of text that appears corrupted or "cursed," created by stacking many random Unicode combining diacritical marks above, below, and through each character until the original letters look like they're dissolving into visual noise. It gets its name from an internet creepypasta character associated with reality-corrupting horror, and the effect became a recognizable shorthand across forums, chat apps, and social media for "something is wrong here" — used for horror-themed posts, edgy jokes, and Halloween content. Combining marks are a real, legitimate part of the Unicode standard — they're what lets a base letter like "e" be paired with an accent mark to form "é". Zalgo text simply exploits that mechanism far beyond its intended use, piling dozens of combining marks onto a single character instead of the usual one or two, which produces the distinctive glitchy, unstable-looking result. This tool takes plain text and generates a Zalgo-styled version by stacking a randomized number of Unicode combining marks above, below, and through each character, ready to copy and paste anywhere Unicode text is accepted.
How it works
A random number of combining marks — drawn from the Unicode combining diacritical marks block (roughly U+0300 to U+036F), which includes marks that render above a character, below it, and through the middle of it — are inserted immediately after each character of your input. Because Unicode explicitly allows a base character to carry multiple combining marks stacked on top of one another, piling on many marks per letter produces the chaotic, corrupted-looking visual effect, even though every character involved is a perfectly standard, valid Unicode code point.

Examples
A glitched greeting
Typing "hello" produces a version stacked with random combining marks that renders as chaotic, "corrupted"-looking glitch text — the underlying letters h-e-l-l-o are all still present, just visually obscured by the added marks.
A short horror-themed caption
Typing a short phrase like "it sees you" and applying the Zalgo effect produces an unsettling, glitch-styled caption suitable for horror or creepypasta-style social content.
Who should use it
- Novelty "cursed" or horror-themed social posts.
- Halloween or creepypasta-style content.
- Gaming or forum community novelty messages.
Industry applications
- Social media novelty content
- Gaming community content
Advantages
- Distinctive, attention-grabbing glitch effect.
- Real Unicode characters, copy-paste ready.
- Randomized output gives a fresh look each time.
Limitations
- Can render inconsistently across platforms.
- May be stripped or flagged by some platforms' spam filters.
- Becomes hard to read with heavy stacking.
Common mistakes to avoid
- Using long Zalgo text in a field with strict length limits — the combining marks count toward character limits even though they add little visible width.
- Applying heavy Zalgo styling to an entire long message, which can become nearly unreadable and may trigger spam or content filters.
- Assuming Zalgo text is a special font — it's standard Unicode combining marks, not a custom typeface.
Best practices
- Use short bursts of Zalgo text for effect, since heavily-stacked marks can become difficult to read and may be flagged by spam filters.
- Test in your target platform first, since rendering and character-limit handling of heavily-stacked combining marks varies significantly between apps.
- Reserve Zalgo styling for a short word or phrase rather than long-form text, to keep it legible and avoid platform issues.
Tips
- For a milder stylized look instead, try the Weird Text Generator or Cool Fonts Style Changer.
- Regenerate if the first result looks too extreme or too mild — each run produces a different random stacking pattern.
