How to use Generate a Zalgo String
- 1. Paste the base text. Type or paste the plain text you want to corrupt into the input pane. Short words work well; long paragraphs become dense and hard to read once zalgo marks pile up.
- 2. Set the intensity. Raise or lower the Intensity number to control how many combining marks stack on each character. Higher values push the text toward unreadable chaos, lower values keep it faintly glitchy.
- 3. Choose where marks attach. Toggle Marks above, Marks through and Marks below to decide whether the corruption grows upward, strikes through the letters, drips downward, or all three at once.
- 4. Copy the corrupted string. Copy the zalgo-ified text from the output pane. Since the result is randomized, regenerate if you want a different arrangement of the same intensity.
When to use Generate a Zalgo String
Generate a Zalgo String turns ordinary text into the glitchy, mark-heavy style associated with cursed text online, by stacking Unicode combining characters onto each letter. It is for chat messages, meme captions and horror-themed text that needs to look corrupted rather than for anything meant to stay readable.
- Posting a cursed message in Discord. You want a message in a server to look glitched out for a joke or a horror-themed channel. Paste your line, dial up the intensity, and copy the result straight into the chat box.
- Styling a horror game's flavor text. An indie game's item description for a cursed artifact should look unsettling. Generate a mid-intensity zalgo version of the item name for the tooltip.
- Testing Unicode rendering in a UI. You want to confirm your app's text renderer handles stacked combining marks without breaking layout. Feed it a heavily zalgo-ified string and check for overflow or clipping.
- Making a meme caption glitch out. A meme template calls for text that looks like it is falling apart. Low intensity with only Marks above keeps the caption legible while still reading as corrupted.

About the Generate a Zalgo String tool
Generate a Zalgo String runs as plain JavaScript in your browser tab, with no server behind it. Convert a string to Unicode mess. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's String Tools section, 159 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with 4 settings, including Intensity, Marks above, Marks through and Marks below, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Does Generate a Zalgo String cost anything?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
