Zalgo Text Generator

Type any text below and it comes back covered in the jittery, corrupted-looking marks known as "Zalgo text" — useful for horror-themed posts, glitch aesthetics, or just messing with a group chat. Everything is generated locally by adding real Unicode combining characters; nothing is uploaded anywhere.

What Is This Tool?

Zalgo text is ordinary text with extra Unicode "combining diacritical marks" stacked above, below and through each character. Those marks are legitimate Unicode characters (normally used for things like accents), but stacking dozens of them per letter creates the jittery, dripping, "corrupted" look associated with Zalgo copypasta and creepypasta since around 2004.

Because it's built from real combining characters rather than an image or font, Zalgo text is still just text — it can be pasted into any text field that accepts Unicode, though how well it renders depends on the app: some platforms cap how many marks they draw per character, which is why the same Zalgo string can look wilder on one site than another.

Why Use It?

Instantly readable-yet-corrupted look for horror or creepypasta-style posts.
Adjustable intensity — from a light "unsettling wobble" to full illegible chaos.
Choose which zones (above, through, below the letters) get marks for different visual effects.
100% private: the text you type never leaves your browser.
Free, no sign-up, no character limit.

How to Use

Type or paste your text into the input box.
Pick an intensity: Low, Medium, or Heavy.
Optionally turn off the "Up", "Middle" or "Down" mark zones to change the style.
Click Generate, then Copy to grab the result.
Paste it anywhere that accepts Unicode text — most chat apps, social media and text fields work.

Example

Input

Hello World

Output

H̛͖́e͙̋l̶̬̃l͈̊͠o̜͐̈ ̧͈̏W̢̙̎o̸̬͌r̠͐͝l͇̒̕d͓̈́͜

Medium intensity with all three mark zones enabled. Heavy intensity stacks far more marks per letter and can make the text genuinely hard to read — that's expected, not a bug.

Practical tips

Start at Low or Medium intensity for anything you actually want other people to read — Heavy is designed to be borderline illegible.
Turning off "Down" marks alone gives a lighter, more "floating" look that's easier on the eyes than the full three-zone effect.
If a platform strips or mangles the marks (some SMS gateways and older databases do), that's the receiving system limiting combining-mark sequences, not a bug in the generator.
Short phrases read better than long paragraphs — the visual noise compounds fast across many characters.

Where Zalgo text actually gets used

The most common use is exactly what it sounds like: horror-themed forum posts, creepypasta, and "cursed" social media captions, where the corrupted look does real aesthetic work. It also shows up in glitch-art design and the occasional prank username.

If you're looking for a different kind of text transformation — readable but stylized rather than corrupted — the case converter or small caps generator do the same "transform this text" job with a much gentler visual effect.

Frequently Asked Questions

Why does my Zalgo text look different when I paste it somewhere else?

Different apps render Unicode combining marks differently. Some browsers and apps cap the number of marks per character to avoid layout problems, so the same Zalgo string can look tamer on Twitter/X than it did in this tool. This is a rendering limit on the receiving app, not something the generator can fix.

Is Zalgo text safe to paste into forms, usernames, or documents?

It's plain Unicode text, so technically yes — but some platforms and databases handle very long combining-mark sequences poorly (excessive height in text fields, or the marks being stripped entirely). Test in Low intensity first if you're pasting into anything important, like a real username.

What's the actual technique behind Zalgo text?

Unicode has a block of "combining diacritical marks" (originally meant for accents like é or ñ) that can be stacked, in theory, without limit on a single base character. Zalgo generators exploit this by randomly stacking many of them — split into marks that render above, through, or below the letter — which is exactly what this tool's intensity and zone controls let you adjust directly.

Can I control how corrupted the text looks?

Yes — the Intensity setting controls how many combining marks get added per character (Low ≈ 2 per zone, Heavy ≈ 10), and the Up/Middle/Down checkboxes let you turn off entire zones, for example keeping only the marks that render above the letters for a lighter effect.

Does this tool store or send my text anywhere?

No. The combining marks are added by JavaScript running in your browser. Nothing you type is uploaded, logged, or sent to a server.
