Zalgo text is plain text that has been buried under layers of Unicode combining marks so it appears to be glitching, melting, or corrupted. The style is named after a creepypasta and is widely used for spooky social-media posts, horror-themed usernames, and the classic “he comes” meme. This generator adds randomised marks on demand with adjustable intensity.
How it works
Unicode defines hundreds of combining characters that have no width of their own — they render on top of the previous base character. Zalgo text exploits three groups: marks that sit above a letter (U+0300 to U+036F upper range), marks that sit below it (lower range), and overlay or mid marks. For every character in your input, the tool appends a random number of marks from the enabled groups, up to the intensity you set. Spaces and existing characters are kept, with marks simply stacking onto whatever came before.
Tips and notes
Higher intensity makes the corruption spill into neighbouring lines, which looks dramatic but can be filtered or clamped by some platforms. If a site rejects or shortens the output, reduce the intensity or disable the up or down direction. Because the underlying letters are unchanged, screen readers and copy-paste still recover the original text, so Zalgo is a visual effect rather than true obfuscation.
