What the CSS Overflow Wrap does
Generate overflow-wrap and word-break CSS for long URLs and tokens. A table cell can break a long API key-like string instead of widening the whole layout Adjust the controls and the preview updates immediately, so you can dial in exactly what you want and copy the result straight into your project — no build step and no account.
One thing to keep in mind: Aggressive word breaking can make normal prose harder to scan.
Private and in your browser
Everything runs locally in your browser. Your input is never uploaded, so the tool stays fast and works offline, and the copy and download buttons always use the current result shown in the output panel.
