Glitch Text Calculator — Zalgo / Corrupted Text Generator
Turn any text into glitch / Zalgo text by stacking invisible Unicode combining diacritical marks above, below, and through each character. Adjust intensity from a subtle shimmer to full chaos, then copy and paste the result anywhere that renders Unicode.

How does this calculator work?
Glitch text is created by appending Unicode combining diacritical marks (U+0300–U+036F) to each character — they stack above and below without taking horizontal space, creating the visual overflow effect. N marks above + N marks below per character; increase intensity to add more marks. Result is copy-pasteable standard Unicode.
Formula
How this is calculated
Unicode includes hundreds of "combining characters" — code points that attach graphically to the preceding character without taking up space of their own. The most familiar are accents: é is the letter e followed by U+0301 (combining acute accent). Stack enough of these above and below a character and it visually "overflows" its line, creating the glitch or Zalgo effect made famous by internet horror culture.
This calculator uses combining diacritical marks from the range U+0300–U+036F, selected deterministically from the character's position and Unicode code point so the output is stable for the same inputs. The intensity slider controls how many marks are added per direction (above and/or below); the direction selector lets you restrict the spill to one side. A mid-overlay (U+0334–U+0338 strikethrough variants) is added in "both" mode.
The result is valid Unicode and pastes correctly into any app, website or chat client that renders Unicode text — though some platforms strip combining characters or cap their stack depth, which can reduce the effect.
Frequently asked questions
The visual effect depends entirely on how the app renders Unicode combining characters. Most modern browsers and desktop apps stack them faithfully; some mobile apps clip long stacks to a fixed height; a few platforms strip combining characters altogether (e.g. some older SMS systems).
Yes — it is standard Unicode text, not an image or special encoding. The characters are harmless combining diacritical marks. However, very high intensity settings can make text hard to read and may cause layout issues in some text fields, so use with caution in form inputs.
The combining mark for each character is chosen deterministically using the character's position in the string and its Unicode code point as a seed. This means the same text at the same intensity always produces the same glitched output, unlike random generators.
