Censor Words in Text

Sanitize sensitive strings using custom mask characters. Maintain structural integrity of log files or code while obfuscating specific tokens.

Input Text

Paste the text you want to process.

Words to censor

Enter words or phrases separated by commas or new lines.

Mask character

Choose the character used to replace matched words.

Match whole words only

Only censor full word matches and leave partial matches alone.

Ignore case

Match words regardless of uppercase or lowercase letters.

Censored text:

Please configure parameters and execute the action.

About This Tool

Censor Words in Text hides chosen words or phrases with a mask character while preserving punctuation, spacing, and line breaks. It is useful for moderation, screenshots, examples, and private notes.

How It Works

Use the tool in three simple steps:

Paste text - Add the text that contains words to censor.
List the words - Enter each word or phrase you want to hide.
Click Censor Words - Instantly replace the matches with a mask.

Basic Examples

Two hidden words

Input:
This draft contains a secret code and a hidden number.

Output:
This draft contains a ****** code and a ****** number.

Custom mask

Input:
Spoiler alert in this paragraph.

Output:
####### alert in this paragraph.

Real-World Usage Scenarios

GDPR Compliance - Redacting PII from Screenshots - Before sharing interface screenshots for support tickets or tutorials, use the tool to mask Personally Identifiable Information (PII) like names, emails, or phone numbers to ensure data privacy compliance.
Security Analysis - Log Sanitization - Clean sensitive API keys, session tokens, or internal IP addresses from server logs before uploading them to public debugging forums or sharing with external consultants.
Professional Documentation - Trade Secret Protection - Prepare internal drafts for external stakeholders by censoring proprietary project codenames or sensitive financial figures while maintaining the original sentence structure and context.
Content Moderation - Community Guidelines - Standardize community posts by replacing blacklisted terms or offensive language with neutral mask characters before publication on managed forums or social platforms.

Frequently Asked Questions

How does the 'Match whole words only' setting affect the output?

When enabled, the tool only censors the exact word. For example, censoring 'pin' will not affect 'shipping' or 'pinball'. Disabling this will mask the sequence of characters regardless of where they appear.

Can I use multiple mask characters for redaction?

The tool uses a single designated character, such as an asterisk (*) or pound sign (#), to replace every character in the target word. This preserves the visual length of the original text while hiding the content.

Is my sensitive data processed on a server?

No. Processing occurs within your browser environment. Your input text and the list of words to be censored are not transmitted to or stored on any external servers.

Does the tool support multi-word phrases?

Yes. You can enter specific phrases by separating them with commas or new lines. The tool will identify and mask the entire phrase as a single entity.
