How to Make Glitch (Zalgo) Text: Step-by-Step

To make glitch text, type your words into the ByteTools Glitch Text Generator, drag the intensity slider to control how corrupted it looks, and copy the result — the tool stacks Unicode combining marks above, through and below each character to create the classic Zalgo effect. It runs entirely in your browser, so nothing you type is uploaded.

This guide covers each step, what the controls actually do, and where the copied text will and won't render correctly.

Step-by-step: from plain text to cursed text

1. Enter your text. Type or paste a word, name or phrase into the input box. A username, a title or a short caption works best.
2. Drag the intensity slider. Move it up for a heavier glitch and down for a subtle wobble. The preview updates live so you can dial in the exact look.
3. Fine-tune the mark direction. Adjust the up, middle and down amounts independently — more up marks make text spike above the line, more down marks make it drip below, and middle marks strike through the characters.
4. Copy the result. When the preview looks right, copy the glitch text and paste it wherever you need it.

What the controls actually do

Glitch text is not a font — it is ordinary characters decorated with stacked Unicode combining diacritical marks. Each slider changes how many of those marks are randomly layered on.

Where glitch text will render

Because the output is standard Unicode, it pastes into most social apps, chat clients, gaming usernames and documents. That said, some platforms trim combining marks or clamp how tall text can grow, so heavily glitched text may appear shorter than your preview — or be blocked in certain input fields entirely. If a destination looks wrong, lower the intensity and copy again.

Privacy and offline use

All the mark-stacking happens locally in your browser with JavaScript. Nothing is sent to a server, logged or stored, which keeps your text private, and the generator keeps working offline once the page has loaded — it can even be installed as a PWA on your home screen.

FAQ

How do I get a subtle glitch instead of a fully cursed look?

Keep the intensity slider low and reduce the up and down mark amounts. A small number of marks gives a wobbly, slightly-off appearance without the text spilling into neighboring lines.

Can I make only the top or bottom of the text glitch?

Yes. Turn up the up-mark amount while keeping middle and down near zero for spikes above the line, or do the reverse for a dripping effect below it.

Why does my copied glitch text look different after pasting?

Some apps strip or limit combining marks for layout safety, so the pasted version can render lighter than the preview. Reduce the intensity for a version that survives more platforms.

Do I need an account or download to use the generator?

No. It is free, requires no sign-up, and runs directly in the browser. You can also add it to your device as a PWA to use it offline.
