Glitch Text Generator

The Glitch Text Generator turns ordinary text into "corrupted" Zalgo-style output by stacking combining Unicode diacritical marks above and below each character. Type any message, choose an intensity from 1 (mild) to 10 (total chaos), and the tool produces a single string you can copy and paste into a chat message, social bio, gaming handle, or piece of horror-themed creative writing. The output remains valid Unicode, every base character is preserved, and the visual chaos is built from officially defined combining marks rather than broken or corrupted bytes.

How to Use the Glitch Text Generator

1. Type or paste your text into the Your text box. Plain words, sentences, paragraphs, and even emoji are all accepted.
2. Drag the Glitch intensity slider to set how many marks are stacked per character. 1 is a subtle accent; 10 floods each letter with marks until it is almost unreadable.
3. Watch the Glitched preview update live on the right. The plain Input pane sits beside it for comparison so you can see exactly how far the corruption has gone.
4. Click Copy glitched text to put the result on your clipboard, then paste it anywhere Unicode is supported (most modern chat apps, social networks, and word processors).
5. Use the Clear button to start over, or pick one of the example presets below the controls to load a starter string.

How the Effect Works

The Unicode standard defines a block of code points from U+0300 to U+036F known as the Combining Diacritical Marks. Each code point in this block is meant to be combined with the preceding base character rather than rendered on its own. An acute accent, a grave accent, a tilde, a dot above, a hook, a ring, all of them live here. When a font renders a base character followed by N combining marks, OpenType shaping stacks the marks above (or, for marks U+0318 and below, beneath) the base glyph, producing the cascading "leaking" effect that defines Zalgo text.

This generator iterates over every code point in your input and, for each one, picks N random combining marks from the U+0300-U+036F range, where N scales linearly with the intensity slider. Marks are placed both above and below the base character so the corruption rises and falls simultaneously. Because the original characters are kept in the string, the result is searchable, copy-pasteable, and accessible to most assistive technology, provided the intensity does not push into extreme ranges.

Intensity scaling is deliberately capped. At the maximum setting of 10, this generator adds up to roughly 15 marks above and 15 below each character. Some experimental generators push past 50 marks per side, but many fonts and chat clients break or refuse to render text beyond about 30 marks per character. Keeping the count between 0 and roughly 15 per side at the top end means the output stays well within the safe zone for almost every renderer in modern use, while still looking thoroughly haunted.

Real-World Worked Examples

Example 1, A gaming username (intensity 5)

You play Phantom Horizon and want a handle that hints at corruption. Start with Shadow.

At intensity 5, the tool might output something like S̵h̶a̷d̶o̵w̷. The base letters are intact; a handful of combining marks cluster above and below each one. The string remains searchable (typing "shadow" in the player search still works), the name still fits inside the 16-character username limit on most platforms, and it has a distinct visual identity.

Example 2, A horror-comedy subtitle (intensity 8)

You are writing a creepypasta caption and need a section heading that feels wrong. Try HE COMES with intensity 8.

The result looks like H̸̢̧̛E̵̱̊ ̵̱̇C̶̰̈́O̷̰̿M̴̰̈́E̸̢̛S̷̰̊, every letter dripping marks. It still reads as "HE COMES" at a glance, but the visual weight is unmistakably menacing. Use intensity 8 or 9 for section headers, chapter titles, and big in-game announcements; lower it for body copy that people still need to actually read.

Example 3, A subtle username flourish (intensity 2)

You want a username that looks elegant rather than scary. Try luna at intensity 2.

The tool will add zero or one mark per side to most letters, producing something like l̐ụ̱n̐ạ. The result is understated, a slight stylish corruption that hints at the aesthetic without overpowering the readability. Intensity 1 to 3 is the right range for everyday usernames, profile bios, and signatures.

Example 4, A short chat message (intensity 10)

You want to send the line lol with maximum chaos. At intensity 10 the tool produces something like l̶̢̛ö̵̱́l̷̰̕, where each letter is buried under a tall stack of combining marks. The result is dramatic; some characters may render partially outside the line height depending on your font. Suitable for one-off jokes; not recommended for repeated use in serious conversation.

Example 5, The empty-input case

If the input box is empty, the output is also empty, the Copy button is disabled, and the preview displays an em-dash placeholder. There is nothing to corrupt, and the tool returns a clean state rather than producing a stray string of marks.

Where Glitch / Zalgo Text Shows Up

• Gaming usernames and clan tags. Many online games (and most chat platforms) allow Unicode in display names. A subtly glitched handle stands out in a lobby list without being unreadable.
• Twitch / Discord / social media bios. Creators in the horror, glitch-art, and alt-aesthetics communities use Zalgo text as a brand marker. Lower intensities are popular for accents; higher intensities for spoopy season bios.
• Creepypasta, horror fiction, and Halloween-themed creative writing. Section headers, dialogue tags for eldritch entities, and corrupted-document props all benefit from glitch text.
• Glitch-art design and album covers. Designers sometimes use Zalgo rendering as an inexpensive visual effect in posters, social cards, and album artwork.
• Messaging pranks and shock-comedy. The "he comes" tradition still survives in casual group chats, Discord servers, and Halloween prank threads.
• Forum signatures and roleplay characters. Some online roleplay communities reserve glitched text for "unhinged", "haunted", or "otherworldly" characters.
• Accessibility testing. Pushing a slider to extreme values and observing how screen readers, search indexes, and chat clients handle the result is a useful exercise when designing Unicode-tolerant systems.

Common Mistakes to Avoid

Mistake 1: Treating intensity 10 as the default. Intensity 10 is dramatic; it is not normal reading material. Reserve the top of the slider for jokes, section headers, and one-off uses. For daily conversation, stay between 2 and 5.

Mistake 2: Assuming every font handles marks the same way. Some monospaced fonts and older operating systems truncate or clip tall stacks. If a particular render does not look the way you expect, lower the intensity or test a different font.

Mistake 3: Ignoring accessibility. Screen readers will usually pronounce the base letters but may speak each combining mark as a separate token (or skip them). Very high intensities make the spoken output sound strange and can be disorienting for visually impaired recipients. Use lower intensities in any context where accessibility matters.

Mistake 4: Expecting the corruption to "lock in" when you paste. Zalgo text is plain Unicode; anyone who pastes your output back into a normalising tool will get the original clean text back. Do not rely on it for security or obfuscation, it is a visual effect, not encryption.

Mistake 5: Forgetting character limits. Each mark counts as a Unicode character. A 5-character username at intensity 10 can balloon to 100+ characters and exceed the platform's limit. Watch the characters in output counter shown below the controls.

Frequently Asked Questions

What is Zalgo text and where did it come from?

Zalgo text is a style of glitched or "corrupted" text produced by stacking many combining Unicode diacritical marks above and below each character. The aesthetic dates to roughly 2004 on the Something Awful forums, where posters used it alongside the phrase "he comes" and creepy ASCII art. The original joke leaned on font rendering quirks, but the effect has since spread across gaming, social media, and creative writing.

Is Zalgo text actually broken Unicode?

No. The output is fully valid Unicode. Every base character is preserved, and the marks that produce the visual effect are officially defined code points in U+0300-U+036F. The result can be displayed by any Unicode-compliant font, indexed by any Unicode-aware search system, and parsed by any standard text tool. The "corruption" is purely visual.

Why does my screen reader read it strangely?

Screen readers usually extract the base letters and skip combining marks, but the exact behaviour depends on the engine. Some readers will announce each mark as a separate token, producing long spoken strings of "tilde, tilde, acute accent" at high intensities. If accessibility matters for your audience, stay at intensity 1 to 3 or provide a clean-text version alongside the glitched output.

Can I undo a Zalgo string back to clean text?

Stripping combining marks is straightforward, most programming languages can filter out code points in the U+0300-U+036F range (and the dedicated "below" block at U+0316-U+031E) in a single pass. If you do not want to write code, search engines and many chat clients also normalise input by collapsing combining marks on display. There is no "encryption" in Zalgo text; the clean version is always recoverable.

Does intensity 10 break browsers or chat apps?

It should not, because this generator caps at roughly 15 marks per side at maximum intensity. Going much higher (30+ marks per side) is where some fonts and clients begin to misbehave. If you are feeding the output into a system with strict length limits or unusual font handling, test with a short sample first.

Will Zalgo text get past spam filters?

Sometimes, sometimes not. Many spam classifiers strip combining marks or treat them as suspicious. Treat Zalgo text as a visual effect, not as a way to evade moderation; if your message is appropriate, you usually do not need glitching to deliver it.

Is this tool really free and does it send my text to a server?

No data leaves your browser. The Glitch Text Generator runs entirely in your page using standard JavaScript, the slider, the random mark selection, and the copy action all happen client-side. There is no signup, no account, and no analytics attached to what you type.

What characters should I avoid pasting in?

The tool handles any Unicode code point, including emoji. It will try to add marks after every character, which means emoji may end up with stacked diacritics that look unusual. If you want glitch text that is purely letters, paste a string of letters; if you want to keep emoji readable, paste them into a separate string and combine the parts yourself.
