Is there a character limit for the text I can process?

The tool handles very large texts entirely in your browser. While there's no hard limit, extremely large files (over 10MB) may slow down your browser depending on your device.

Is this tool free and does it store my text?

Yes, it's completely free. Your text is processed locally in the browser — nothing is uploaded or stored on any server.

Does this work offline?

Once the page is loaded, most processing works even if your internet connection drops, since everything runs client-side in JavaScript.

Can I use this tool for professional or commercial projects?

Absolutely. There are no restrictions on how you use the results. Feel free to use the output in any personal or commercial project.

Does the tool support Unicode and special characters?

Yes, all text tools on WebToolsBox fully support Unicode, including emojis, accented characters, CJK characters, and other special symbols.
