What is Zalgo text?

Zalgo text — also called glitch text, cursed text or corrupted text — is plain text that has been buried under stacks of Unicode combining diacritical marks. These marks were designed so that languages could place accents on letters: a tilde over an n, a cedilla under a c. Crucially, a combining mark has no width of its own; it simply attaches to whatever character came before it.

Nothing in the Unicode standard says how many marks a single letter may carry. Stack fifty of them on one character and the font renderer dutifully draws all fifty, climbing upward and sinking downward until the letter disappears into a thicket of hooks and dots. That is Zalgo.

The result is genuinely just text. You can copy it, paste it, and it travels through any system that handles Unicode — which is why it shows up in Discord servers, YouTube comments, Instagram bios and horror-themed memes rather than being confined to image editors.

Where the name comes from

Zalgo began as an internet creepypasta character created around 2004 by animator Dave Kelly, who edited newspaper comic strips so the characters slowly descended into madness while ominous text crawled across the panels. The recurring phrase attached to the character — often rendered as “he who waits behind the wall” — became a running joke on forums such as Something Awful and 4chan.

When someone worked out that combining marks could produce the same visual dread in ordinary text, the style inherited the name. Two decades later the character is largely forgotten while the text effect is more popular than ever, mostly stripped of its horror origins and used simply because it looks striking.

Choosing the right craziness level

The slider controls how many marks are attached to each character. More marks means more distortion — and less chance the text survives a platform's height limits.

You can also switch off individual mark groups. Turning off marks below keeps the corruption above the line, which is the safest choice for a single-line username field. Turning off marks through keeps the base letters clearly readable.

Where Zalgo text works (and where it does not)

Rendering depends entirely on the app, not on the text itself. Here is roughly what to expect:

Ideas for using Zalgo text

• Halloween posts — a caption that looks like it is decaying beats another pumpkin emoji.
• Horror and ARG content — creators use escalating corruption to signal that something is wrong.
• Game and stream titles — a lightly glitched title stands out in a crowded sidebar.
• Discord roles and channel names — servers use light Zalgo for a distinct visual identity.
• Memes about broken software — nothing says rendering error like actual rendering chaos.
• Thumbnails and cover art — screenshot the output and drop it into your image editor.

Two things to avoid: do not use Zalgo in anything anyone needs to read quickly, and do not spam it in communities that have asked people not to — most moderation rules treat walls of corrupted text as disruptive.

Accessibility: please read this part

Screen readers announce combining marks. A single Zalgo word can be read aloud as dozens of accent names in a row, which is genuinely unpleasant for anyone relying on assistive technology — and in a username it repeats on every message.

So: use it for effect in a caption, a thumbnail or a one-off post. Avoid it in display names, in accessibility-focused communities, and anywhere someone might need to read your text rather than look at it. Fun and considerate are not mutually exclusive.
