Zalgo Text Generator

The Zalgo Text Generator is a free browser-based tool that transforms ordinary text into eerie, glitchy "Zalgo" text by layering Unicode combining diacritical marks above, through, and below each character. The resulting text appears distorted and corrupted, creating a visual effect that has become iconic in internet culture, memes, and creative writing.

Zalgo text works by exploiting a feature of the Unicode standard: combining characters (code points in the U+0300–U+036F range and beyond) are designed to stack on top of or below a base character. By adding many combining marks to a single character, the text overflows its normal line height and creates the characteristic "glitch" look. This is not a font change or image — the output is real, copyable Unicode text that works anywhere Unicode is supported.

The tool provides granular control over the output. You can adjust the intensity from low (subtle) to insane (maximum distortion), and toggle which directions receive combining marks: up (above the text), middle (overlay/strikethrough), and down (below the text). You can also use the Clean button to strip all combining marks from text, which is useful for restoring zalgo-ified text back to its readable form.

Everything runs entirely in your browser using JavaScript string manipulation. No data is sent to any server, and no input is stored or logged. If you work with Unicode frequently, you may also find our Unicode Inspector useful for analyzing individual code points, our Text Case Converter for changing letter casing, or our ROT13 Cipher for simple text obfuscation.

Whether you are creating creepy usernames, spooky social media posts, Halloween-themed messages, or simply experimenting with Unicode, this tool gives you full control over the zalgo effect in real time.

1. Type or paste your text into the Input textarea on the left.
2. Adjust the Intensity slider to control how many combining marks are added per character (Low, Medium, High, or Insane).
3. Toggle the direction checkboxes to choose where combining marks appear: Up (above), Middle (overlay), Down (below).
4. The zalgo output appears instantly in the Output panel on the right.
5. Click Regenerate or press Ctrl+Enter to generate a new random variation with the same settings.
6. Click Copy or press Ctrl+Shift+C to copy the output to your clipboard.
7. Use the Clean button to strip all combining marks from the input, restoring it to plain text.
