Zalgo Glitch Text

What this tool does

The Zalgo Glitch Text tool corrupts your text with stacks of random Unicode combining marks — the invisible accent-like code points that attach to the character before them. When enough of these stack up above, through, and below every letter, the result looks chaotic, distorted, and deliberately broken. The effect is often called “zalgo” or “cursed text” after an internet horror meme from the late 2000s that popularised the visual style. Output is generated entirely in your browser, no network connection required.

Why you might need it

Zalgo text has a clear aesthetic niche: anything where you want to signal chaos, corruption, unreliability, or an unsettling presence. Horror writers use it for in-universe documents that appear to be “glitching.” Game designers drop it into chat logs or in-game text when something has gone wrong with a simulation or an artificial mind. Graphic designers and social media creators reach for it when they need a visual that reads as digital distress without any image editing.

Beyond horror, the style appears in memes, parody, and internet humour whenever something is supposed to look extremely wrong. A screenshot of a perfectly normal message written in zalgo text becomes a joke by itself because the visual register is so immediately recognisable to anyone who has spent time online.

The intensity control makes the tool useful across a spectrum of contexts. At Low intensity, the effect is subtle enough to feel slightly off without being illegible — useful for dramatic headings. At High intensity, the output overflows its lines aggressively and becomes genuinely difficult to read — the right choice when maximum visual chaos is the goal.

How to use it

1. Choose an intensity — Low, Medium, or High — using the control at the top.
2. Type or paste your text into the input box. The glitched output appears immediately below.
3. Click Regenerate at any time to get a fresh random arrangement of marks for the same text and intensity.
4. Click Copy to copy the output to your clipboard.
5. Use Load sample to try the tool with a ready-made phrase, or Clear to start over.

Common pitfalls

The most common issue is pasting into a platform that strips or limits combining marks. Some social networks and messaging apps normalise Unicode on the server side, removing excessive combining marks to prevent layout breakage. If the effect disappears after you paste, the platform is filtering it. There is no workaround for this — it is a server-side policy.

A related issue is that at High intensity, the zalgo text can overflow into surrounding lines in interfaces that do not clip line height. In a bio or a profile field this is usually fine. In a document or a chat thread it may push other users’ messages around visually, which can be disruptive. Medium is usually the safer default for shared contexts.

Screen readers encounter combining marks as pronunciation modifiers and usually produce garbled, meaningless output. Zalgo text is entirely decorative and provides no information in an accessible form, so it should never be used for content that needs to be readable by assistive technology.

Tips and advanced use

Because each Regenerate produces a genuinely different arrangement, it is worth clicking several times and comparing before settling on the version you paste. Some random arrangements are denser in one area of a word, or create an interesting visual rhythm, that another arrangement does not. The randomness is a feature rather than a bug.

Pair zalgo text with a plain-text label in image captions or post descriptions when the glitch text is the headline. Visitors using screen readers or text-only browsers see the plain label; sighted visitors see the visual effect. This way you get the aesthetic benefit without sacrificing reach.

For creative writing and alternate-reality games, Low intensity is often the most effective setting, because it keeps the text technically readable while still looking wrong — exactly the feeling you want from a corrupted system message or an in-fiction artefact that has been damaged.
