The "Profanity Remover" tool is a free utility that finds offensive or vulgar words in any text and either masks them with a replacement character or deletes them entirely. Paste a paragraph, a comment thread, or a user-generated review, choose a mode, and the cleaned version appears instantly in the output field - ready to copy or download.

Unlike a simple word search, this tool recognizes the ways people disguise profanity. It normalizes text before matching, so it catches leetspeak ("sh1t"), letter repetitions ("shiiit"), character substitutions ("bullsh!t"), and mixed case. A whole-word mode (on by default) protects innocent words like "pass" or "class" from being mangled by a match on "ass".

Everything runs locally in your browser with JavaScript, so your text never leaves your device and nothing is uploaded or stored. The tool is free, needs no account, and works on any modern browser - handy for forum moderators, community managers, and anyone who needs to keep content family-friendly.

The tool scans your text and runs it against a built-in list of common English profanity, plus any custom words you add. In "Replace with character" mode, each detected word becomes a mask of your chosen symbol (the default is *), so "sh1t" becomes "****". In "Remove completely" mode, the offending word is deleted and any leftover double spaces are tidied into a single space.

Because the matcher normalizes the text before comparing, obfuscations that would beat a plain word search are caught too: leetspeak ("4ss" for "ass"), repeated letters ("fuckkk"), common substitutions ("a$$" or "bullsh!t"), and mixed casing. Matching is case-insensitive, so "Damn", "DAMN" and "damn" are all caught the same way. Turn off "Whole word only" to remove or mask a term even when it appears inside a longer word.

Moderate user comments, reviews, or forum posts before publishing them, so the conversation stays civil and family-friendly.

Sanitize community or live-chat content that must comply with a platform's community guidelines before it goes live.

Clean up student writing, workshop submissions, or name lists as an easy first pass - then review the output to confirm the tone is right.

Pre-check a draft for accidental strong language before it's shared where a slip of the tongue could be embarrassing.

FAQ 1: What is the difference between the two modes?
Answer: "Replace with character" masks each bad word with a symbol (the default is *) so the text keeps its original length and rhythm. "Remove completely" deletes the word and cleans up the leftover spaces, so the sentence reads more like natural speech.

FAQ 2: Does it really catch words like "sh1t" or "a$$"?
Answer: Yes. The matcher normalizes both the word list and the text, so common obfuscations - leetspeak like "4ss", letter substitutions like "a$$", repeated letters like "shiiit", and mixed casing - are all caught automatically.

FAQ 3: Why did my legitimate word get changed?
Answer: With "Whole word only" on (the default) this should not happen, because only complete words are matched. If a real word still gets flagged, it is likely a false positive on a term that shares letters with the built-in list - you can avoid it by keeping the filter in whole-word mode.

FAQ 4: How do I add my own words?
Answer: Type them in the "Custom bad words" box, separated by commas or one per line. They are added to the built-in list and checked with the same smart matching, so they catch disguised versions too.

FAQ 5: Does this tool change my original text?
Answer: No. The "Input" field is never modified; only the copy in the "Output" field reflects the filtered result and your chosen options.

FAQ 6: Is my text private?
Answer: Yes. The tool runs entirely in your browser with JavaScript. Your text is never uploaded to or stored on our servers.
