How to censor a video and bleep out swear words
To censor a video, you bleep or mute each swear word in the sound, then star out or blur any that show on screen. Here's how to censor a video for free, on your device, how to bleep out words by hand in CapCut and Premiere Pro or on a phone, how long a bleep should be, and how to censor the captions too.

In short
- The quickest free way: open your video in the bleep censor. It transcribes the speech on your device, marks the swear words, and lets you click any word to bleep it or not. Choose a bleep or silence and download it.
- A bleep, silence and a sound effect all count as censoring. Pick by tone: a bleep for most videos, silence for serious ones, a sound effect when the censor is part of the joke.
- A bleep should cover the whole word, from just before its first sound to just after its last, with the word itself muted underneath.
- Censor what's on screen too: star the word out in the captions (f***) and blur any text that shows it.
- By hand: split the clip around the word, turn that piece's volume down and lay a beep over it, in CapCut on a computer or a phone. Premiere Pro's Censor tool does it from the transcript.

How to censor a video for free
The quickest way to censor a video is the free bleep censor. It finds the swear words and bleeps them in your browser, on your device: nothing is uploaded, there's no watermark and nothing to sign up for.
- Open your video or a sound file, up to 30 minutes long.
- Let it transcribe the speech. It does it on your device, with the same speech model as the free auto caption generator. The model downloads once.
- Check what it marked. It finds swear words from a built-in English list: the strong ones by default, and milder ones like “damn” or “hell” if you check that box too. Every word of the transcript is shown, so click any word to bleep it or not.
- Add your own words. A name, a brand, a place: add it and it's bleeped everywhere it's said, in any language the transcript is in.
- Choose a bleep (a beep tone) or silence, and play the video back with the bleeps.
- Download it. The picture is copied as it is, so it loses no quality; only the sound is re-encoded. A sound file comes back as an MP3.
It can also download the captions as an SRT file with the bleeped words starred out, so captions you add later match what viewers hear. That's further down, with the rest of what's on screen.
Automatic transcription can miss a word: one that's mumbled, said over someone else, or slang the list doesn't have. Play the whole video back once before you post, and click any word it missed.
Bleep, mute or a sound effect: which to use
There are four ways to take a word out of the sound, and any of them does the job for the platforms: YouTube's ad guidelines count a bleeped or muted word as “obscured profanity”, the kind that can still earn full ads (the rest of YouTube's rules are in can you swear on YouTube?). So the choice is about how the video sounds:
| Way | What viewers hear | Use it for | Watch out for |
|---|---|---|---|
| Bleep | A tone over the word: traditionally a 1,000 Hz (1 kHz) sine wave, the one TV and radio use | Most videos. Everyone knows what it means, and a joke usually survives it | A tone much louder than the voice is harsh, especially on headphones |
| Silence (mute) | A gap where the word was | Calm, serious or professional videos. Live broadcasts often mute rather than bleep | One short gap reads as censoring; long or frequent ones sound like the audio dropped out |
| A sound effect | A horn, a quack, a record scratch | Comedy, gaming and stream clips, where the censor is part of the joke | It pulls attention. Used on every other word, it's all people hear |
| Cutting the word out | Nothing: the sentence jumps ahead | Talking-head videos that already have jump cuts | The picture jumps too, and the sentence can end up saying something else |
Whichever you pick, keep it the same through a video, and ideally through a channel. A bleep in one clip and silence in the next sounds like a mistake rather than a choice.
How long a bleep should be
As long as the word, and a hair more. A bleep should start just before the word's first sound and end just after its last. Start late and the first letter slips out (“f-”); stop early and the end of the word does. Half-censored swears happen at the edges, and the start of a word is what gives it away.
- Mute the word under the bleep. A tone laid on top of the word only competes with it, and the word comes through underneath. In an editor, turn that stretch of the voice down to nothing first, then add the bleep.
- Match the voice's loudness. A bleep far louder than the speech makes people jump, and makes the swear more noticeable, not less. Set it about as loud as the voice around it.
- Bleep a run of swears as one. Three short bleeps in two seconds sound busier than one longer one over the whole phrase.
- Mind the lips. If the word is easy to lip-read, a bleep only does half the job. Broadcasters put a bar or a blur over the speaker's mouth when that matters; how to blur part of the picture is below.
- Listen to every one. Play each bleep back on headphones, listening for a sound at either edge.
How to bleep out words in CapCut and Premiere Pro
CapCut on a computer. You do it word by word, with the split tool, the volume and a beep from CapCut's sound effects:
- Move the playhead to just before the word and click Split in the toolbar (Ctrl+B, or Cmd+B on a Mac). Move it to just after the word and split again.
- Select the short piece in the middle and turn its volume all the way down in the Audio tab on the right. Don't delete it: the picture would jump and everything after it would move up.
- Open Audio in the left toolbar, then Sound effects, and search for “Beep”. Add one and move it on the timeline so it sits over the muted piece.
- Trim the beep to the length of the gap, set its volume, and export.
That's a minute or two a word, which is fine for one swear in a clip. Menu names move between CapCut versions, but the steps don't: split, mute the middle, lay a beep over it.
Premiere Pro. Premiere's Censor tool works from the transcript, in Text-Based Editing, so it finds every use of a word at once:
- Turn on Automatic transcript under Settings when you import the clip, so Premiere transcribes it.
- Open the Text-Based Editing workspace from the Window menu, put the clip on the timeline and find its transcript in the Text panel.
- Click the ellipsis (more options) button, open the censored words list, add your words one by one or import a list, and Save.
- Click Filter and choose Censored words to highlight them in the transcript.
- Click Apply Effect and choose the bleep, silence or a sound of your own, then Apply for the selected word or Apply to all.
Adobe says Premiere mutes the word with an Amplify effect and cuts the bleep in on a new track, so your own volume levels stay as they were. To bring a word back, remove that effect, or its keyframes, in Effect Controls. The tool first appeared in the Premiere Pro beta in August 2025 and is in the regular release from version 25.6: if you can't find the censored words list, update Premiere.
How to censor a video on your phone
CapCut's app does the same as the computer version, by touch:
- Start a new project with the video. Tap the clip, move the playhead to just before the word and tap Split. Split again just after it.
- Tap the piece in the middle, tap Volume and drag it to 0.
- Tap Audio, then Sound FX, search for “beep” and add one where the muted piece is. Drag its ends to fit the gap.
- Export.
On a small screen, landing a split exactly at the edge of a word takes some zooming in, so it's fine for a word or two and slow for more. A clip with a dozen swears is quicker on a computer, in the free bleep censor.
For the captions, there's no timeline to fiddle with if the clip came from Clyper: its clip editor works on phones, and you tap a caption word to change it or hide it (more below).
How to censor captions and text on screen
A bleep only censors the sound. If the clip has captions, every word is on screen too, so a bleeped clip with “f**k” in its captions isn't censored at all. YouTube's guidelines treat written words the same way: covering them with black bars, symbols or text added in post-production counts as obscuring them.
- Captions: star the word out. Write it as f*** or f**k, or leave it out. The bleep censor's SRT already has the bleeped words starred: open it with the bleeped video in the free add captions to video tool to burn the captions in, word by word, in the 5 styles clips use. Making captions from scratch? The auto caption generator lets you edit any word before you download an SRT or burn them in.
- Text in the picture: blur it. A swear on a sign, a shirt, a phone screen or a stream's chat needs covering too.
- In CapCut on a computer: copy the clip and paste it on a track above. Add Effect, Video effects, Blur to the original underneath. Select the copy on top, open Mask in the Video tab, choose a rectangle, drag it over the text and click Reverse, so only that spot shows the blurred clip below.
- In Premiere Pro: draw a mask over the text with the mask tools in the Toolbar, click Track selected mask forward and backward in Effect Controls so it follows the text, then add Gaussian Blur from the Effects panel.
- Already on YouTube: in YouTube Studio on a computer, open the video, then Editor, Blur and Custom blur. Drag the box over the text (Track object makes it follow something that moves) and Save. YouTube notes that since June 2025, changes saved in its editor can't be undone with Revert to original.
- The mouth, if it matters. The same blur or a plain bar over the speaker's lips stops people reading a word the bleep took out.
- Titles and thumbnails. They're where YouTube is strictest about swearing, and a bleep doesn't reach them. Write the word with stars there too.
Why creators and clippers censor swear words
- Ads. Swearing in a YouTube video doesn't cost it its ads on its own, but swearing in the title or thumbnail, or in most sentences, does, and a video built around swearing can be age-restricted. The full rules, with TikTok's and Instagram's, are in can you swear on YouTube?
- Brand deals and clipping campaigns. Brands decide what their name appears next to. Some campaigns want clean clips and some don't mind, so check the campaign's rules before you post, and bleep what they ask. Finding and reading a campaign brief is covered in how to find clipping campaigns.
- Clips that run as ads. If a brand puts your clip in an ad on Facebook or Instagram, Meta's ad standards apply, and they're stricter than its rules for posts: stars or symbols in place of letters still count as profanity in an ad, while bleeped or covered audio and fully blurred words are allowed, as long as they aren't used excessively.
- Where people watch. Clips play at work, in class, on a speaker in a room full of people. A bleep keeps the joke and loses the reason to scroll past.
- Someone asked. A guest who named a person they shouldn't have, or a brand you can't mention: that's what adding your own words in the bleep censor is for.
Censoring podcast and stream clips
Most swearing in short clips comes from podcasts and streams: hours of people talking off the cuff. Bleeping a clip takes a minute. The slow part is everything before it: finding the moments worth clipping in a three-hour episode or VOD, cutting each one cleanly, framing it vertically and captioning it.
That's the part Clyper does. Paste the YouTube link, or upload the episode (MP4, MOV, WebM or MKV, up to 4 GB), and it reads the transcript to find the moments that stand on their own, cuts each one on whole sentences, scores its hook, frames it 9:16 on whoever's talking (on a stream, the webcam over the game) and captions every word in one of 5 animated styles. More in podcast clips with Clyper, and the workflow in how to clip podcasts.
Clyper doesn't bleep the sound, so censoring is two steps. In its clip editor, tap any caption word to change it (to f***, say) or leave it empty to hide it: its timing stays, edits don't cost credits, and it works on a phone. Then download the clip and run it through the free bleep censor, which bleeps the sound and copies the picture, captions included, as it is. For how big and where the captions should sit, see how to caption short videos.
Questions
How do I bleep out swear words in a video for free?
Open the video in the free bleep censor. It transcribes the speech on your device, marks the swear words, and lets you click any word to bleep it or not; choose a bleep or silence, play it back and download. The picture is copied as it is.
What sound is used to bleep out swear words?
Traditionally a 1,000 Hz (1 kHz) sine tone, the bleep TV and radio use. Silence works too, and comedy and gaming clips often swap in a sound effect such as a horn or a quack.
How long should a bleep be?
As long as the word, plus a hair either side: start just before its first sound and end just after its last, with the word muted underneath. Starting late lets the first letter through, which is what gives a swear away.
How do I censor a swear word in captions?
Replace it with stars, as in f***, or leave it out. The free bleep censor downloads an SRT with the bleeped words already starred, which the add captions to video tool can burn in; in Clyper's clip editor, tap the word and change it.
How do I blur a word or text in a video?
In CapCut, put a sharp copy of the clip over a blurred one and mask a hole in it over the text. In Premiere Pro, track a mask over the text and add Gaussian Blur. For a video already on YouTube, use Blur, then Custom blur, in YouTube Studio's editor on a computer.
Can Clyper bleep swear words in clips?
Not the sound. Clyper finds, frames and captions the clips, and its clip editor lets you change or hide any caption word. To bleep the sound, run the downloaded clip through the free bleep censor, which copies the picture as it is.
