Glitch Text Generator
Turn ordinary Unicode text into a dense, copy-ready glitch effect by attaching deterministic combining marks to each character.
Input
Required. Enter 1 – 1,000 Unicode code points. Line breaks are preserved without added marks.
Result
Glitch textGenerated 108 Unicode code points from 12 source code points.
How to use this glitch text generator
What this calculator does
This generator converts ordinary text into a “glitch” or Zalgo-style string by adding Unicode combining marks after each non-line-break character. The marks have their own code points but are designed to combine visually with the preceding base character, so several can appear stacked above, through, or below a letter. The generator uses a fixed profile of eight marks per transformed character and a deterministic selection rule: the same source text produces the same result every time. That makes the visible result and the Excel export reproducible. It is a text transformation utility, not an encryption tool, font file, security test, or guarantee that every app will render the marks identically.
When to use it
Use it when you want a deliberately distorted heading, meme caption, horror-themed message, game handle experiment, or visual text sample for testing how a layout copes with combining characters. It is also useful for learning how base characters and combining marks coexist in Unicode. For production interfaces, keep the result short and test the destination first, because some systems normalize, filter, truncate, or render dense combining sequences differently.
How to calculate
- The calculator opens with a complete demonstration value, Hello world!, and a valid example workbook, so the first result and Download Excel action are immediately usable.
- Replace the text in Enter your text with the content you want to transform. The result updates automatically; there is no separate Calculate button.
- Read the generated value under Glitch text. Line breaks stay as line breaks; every other source code point receives eight deterministic combining marks.
- Choose Download Excel to export the current source text, generated text, transformation counts, and a per-character detail sheet as a real XLSX workbook.
- Choose Reset to clear the demonstration and all calculated/export state. After Reset, Excel download is disabled until you enter a complete valid text value again.
Input guide
Enter your text is the only semantic input. It is required and accepts ordinary Unicode text, including letters, digits, punctuation, spaces, emoji, tabs, and line breaks. The supported range is 1 to 1,000 Unicode code points. A realistic value is Hello world!. Adding more source characters makes the generated output longer because each transformable character gains eight marks; deleting characters shortens it. Do not confuse visible glyph count with code-point count: an emoji may be made from multiple code points, and a combining mark is a code point even though it has no independent horizontal width. Empty input, unsupported isolated surrogate code units, or more than 1,000 code points is rejected visibly instead of being silently changed. The input is not normalized before transformation, so canonically equivalent strings can remain distinct code-point sequences.
Output guide
Glitch text is the transformed Unicode string. It is an exact deterministic conversion for this generator's fixed eight-mark profile, not a probability, recommendation, or measurement estimate. Its appearance is driven entirely by Enter your text and by the destination font/rendering engine. A short source produces a short transformed string; a long source produces a proportionally longer one. Reset produces the documented empty state rather than retaining the startup result. If a destination strips combining marks, the pasted result may look closer to the original source even though this page generated the marks correctly.
Worked example
The startup example contains 12 source code points in Hello world!. There are no line breaks, so all 12 code points are transformed. At eight combining marks each, the generator adds 96 marks. The output therefore contains 108 Unicode code points in total: 12 original code points plus 96 added marks. The exact first-open deterministic result is repeated below and is the same value written to the startup workbook.

The Unicode Standard explains that combining characters follow the base character to which they apply; its discussion of base characters and combining-character sequences is the most useful foundation for understanding why this effect works. Unicode normalization can reorder or compose certain canonically equivalent sequences, so the Unicode Normalization Forms specification is relevant when a platform changes text after copy-and-paste.
Why glitch text can look different between apps
Combining marks are characters, not a special downloadable font. Their placement depends on the shaping and rendering system used by the browser, operating system, font, editor, or social platform. A combining mark normally has no advance width, so it can share horizontal space with the preceding base character. Stacking several marks exaggerates this normal Unicode behavior and creates the dense visual effect.
Normalization is a separate process from rendering. Two strings can look the same while containing different code-point sequences, and normalization can convert canonically equivalent sequences to a common form. JavaScript exposes this behavior through String.prototype.normalize(). This generator deliberately leaves the source sequence unnormalized before applying its marks so that it does not silently rewrite the user's original code points.
Practical limits and common mistakes
Dense combining text can increase storage size and visual line height much faster than its base text suggests. That makes very large strings a poor fit for constrained fields such as usernames, database keys, email addresses, domain names, or systems with strict character policies. Some destinations may remove marks for safety or normalization, while others may show unusually tall lines. The 1,000-code-point input limit keeps this browser-based tool responsive and keeps the generated XLSX comfortably within Excel's cell-text limit for the supported transformation profile.
