It keeps the same structure, spacing, and line formatting while fully masking the original content. This makes it ideal for creating mock data, redacting sensitive text, or preparing placeholder layouts.

Hide this message completely.

Replace each character with:

*

**** **** ******* **********

34

Common Use Cases:

Designers and developers use this tool to fill layouts with masked text. Writers and editors use it to redact content before publishing drafts. It’s also handy for testing document flow, showing character count without context, or building distraction-free input previews. Whatever the use, this tool helps you mask text instantly and cleanly.

Useful Tools & Suggestions:

If you’re scrambling content for privacy or testing, Anonymize Text is a solid pair it helps replace names and identifiable info without breaking readability. And for an extra twist, Add Fuzziness to Text introduces small distortions that keep your content legible but less predictable. Both are useful for masking real data while maintaining structure.
