Glitch Text Generator

The Zalgo effect: how stacked marks break the grid

Text rendering assumes characters sit politely in a line. Unicode combining marks — designed so any language can attach accents to any base letter — have no stacking limit, and glitch text exploits that: pile a dozen marks above and below each letter and the text erupts out of its line, overlapping neighboring rows. The style is nicknamed Zalgo after a 2004 internet-horror meme in which corrupted text signaled an approaching entity; the look became shorthand for digital corruption across memes, games, and horror ARGs.

This generator is deterministic — the same input and intensity always produce the same output — so your glitched username stays reproducible.

Using glitch text without breaking things

Platforms defend themselves differently: some cap rendered mark height (Twitter clips extreme stacks), some strip marks in usernames, and dense Zalgo can slow older devices — a handful of sites even filter it as spam. Practical guidance: low intensity survives almost everywhere and reads clearly; high intensity is for maximum chaos in posts rather than names. Avoid it in accessibility-sensitive contexts — screen readers announce every combining mark or fail silently, so glitched text is effectively invisible to blind users.
