Turn normal text into "corrupted"-looking Zalgo text by stacking Unicode combining marks above, in the middle, and below each character. Adjust the intensity and toggle each mark zone on or off.
⚠️ Very high intensity may be flagged as spam or unusual text and get blocked or restricted on some platforms (messaging apps, social media, etc.).
Zalgo text is an internet meme style that stacks Unicode combining diacritical marks above, below, and in the middle of letters to create a "corrupted" or "glitchy" look. It originated in creepypasta communities as a way to represent cursed or haunted-looking text, and has since become a widely used novelty effect across the internet.
Unicode allows a single base character to have many combining marks attached to it with no hard limit. This tool randomly picks marks from the "above," "middle," and "below" zones and stacks them onto each character. The higher the intensity setting, the more marks get stacked per character — producing a denser, more unreadable "glitch" effect.
Heavily zalgo'd text can break layouts in some apps or websites, get caught by spam filters on messaging platforms and social media, or become hard to read and search for. If you need the text to stay legible and safely postable, use a lower intensity, and it's worth testing on the target platform before sharing anything important.
