About Zalgo Text
Corrupt text with stacking diacritical marks for creepy, glitchy, watchers-beyond aesthetics.
Unicode combining marks stack onto the previous character instead of advancing. This tool showers each letter with random above, below, and strikethrough marks — light dusting to full corruption — while leaving spaces intact for readability.
Heavy output can lag weak renderers and confuse screen readers; use sparingly and never for essential information. Everything runs in your browser.
Where it is used
Horror writing, Halloween posts, meme captions, and game flavor text.

Frequently Asked Questions
- Why does heavy zalgo lag some apps?
- Hundreds of stacked marks stress text layout engines. Medium suits most uses; heavy is for screenshots, not chat.
- Can this break databases or forms?
- Overlong strings can exceed naive length limits. Normalize (NFC) and length-cap untrusted input server-side.
- Do screen readers cope?
- Badly — they may spell every mark. Keep zalgo decorative and provide plain equivalents.
