Adjust the Volume of a Video Online for Free

Make a video's sound louder or quieter without re-rendering a single frame. Set a volume level by hand — anywhere from silence to four times louder — or let the tool normalize it automatically, either to a peak level or to a proper loudness standard of the kind broadcasters and streaming platforms use. The picture is copied across untouched, so only the audio is written again and the video quality is exactly what you started with. No sign-up and no watermarks.

How to Make a Video Louder

  1. Click the upload area above or drag and drop your video (up to 10 MB).
  2. Choose Manual and set a level (0–400%), or choose Normalize and pick a target loudness.
  3. Apply and download your video.

Three Ways to Do It

  • Manual volume – a slider from 0% (silent) up to 400% (four times louder), with 100% leaving the audio exactly as it is. Use it when you know roughly how much you want and would rather decide yourself.
  • Normalize to peak – finds the loudest single moment in the video and lifts everything so that moment reaches your target. Predictable, and the right choice for a clip that is simply quiet throughout.
  • Normalize to loudness – measures how loud the audio actually sounds to a listener, rather than how high its tallest peak is, and adjusts to hit a loudness target. This is the EBU R128 standard that broadcasters and streaming platforms use, and it is the one to pick when peak normalizing has not helped.

Peak or Loudness? The Setting That Matters

These two options both make audio louder, but they do it in different ways.

Peak normalizing looks only at the loudest moment in the recording. For example, imagine a quiet interview with a sudden door slam. The door slam may already be close to the maximum level the audio can handle. Because of that one loud sound, the software cannot raise the whole recording very much. The result is that the person's speech may still sound too quiet, even after peak normalization.

Loudness normalizing looks at the overall loudness of the recording rather than just its single loudest moment. It can raise the level of quiet speech while keeping louder sounds, such as a door slam or cough, from becoming excessively loud.

For example, if an interview is mostly quiet but contains one loud bang, loudness normalization can make the interview easier to hear without simply making the bang much louder.

If your recording sounds too quiet and peak normalization doesn't make enough difference, try loudness normalization.

When You Might Need This

  • A video recorded too far from the microphone that you can barely hear
  • A clip that is fine on headphones but inaudible on a phone speaker
  • Footage that blasts out far louder than everything else in a playlist
  • Several clips at different levels that need to match before editing them together
  • A talk or lecture filmed from the back of a room
  • Video going to a platform with its own loudness rules, which you would rather meet yourself
  • A screen recording where the system sound came out too low
  • Audio that needs pulling down so a voiceover can sit on top of it

Frequently Asked Questions

For a clip that is simply too quiet, choose Normalize and the loudness option — it works out how much lift the audio needs and applies it, without you guessing at a number. If you would rather decide yourself, switch to Manual and push the slider above 100%: 200% is twice as loud, 400% is the maximum. Either way the picture is untouched, so there is no quality cost to trying it.

Switch from peak to loudness. Peak normalizing is limited by the single loudest moment in your video — if there is a bang, a cough or a bump anywhere in it, that instant is already near the ceiling and nothing else can be raised. Loudness normalizing measures how loud the clip actually sounds instead, so it lifts the speech properly and keeps the peaks in check. It is the fix for exactly this situation.

LUFS is the unit used to measure perceived loudness — how loud something seems to a listener, rather than how tall its waveform is. Two clips can have identical peaks and still sound nothing alike, which is why peak measurements are a poor guide to loudness. Broadcasters and streaming platforms all normalize to LUFS targets for this reason, and the loudness option here uses the same EBU R128 standard.

Not the picture. The video stream is copied across untouched rather than re-encoded, so every frame is bit-for-bit what you uploaded — this is the main advantage of doing it here rather than re-exporting from an editor. Only the audio is written again, as AAC at 192 kbps, which is a high setting. Boosting very quiet audio does raise any background hiss along with the voice, since the tool cannot lift one without the other.

You will get a clear message saying no audio stream was found, rather than a silent failure or a broken file. Some recordings genuinely have no audio track — screen captures made without system sound, or footage from a camera with the microphone disabled — and there is nothing to adjust in that case. Volume tools can only change sound that already exists; they cannot create it.

Very large boosts on already-loud audio can clip. If a manual boost sounds harsh, try a smaller increase or use Normalize, which targets a consistent level rather than just amplifying.

No. The video stream is copied as-is and only the audio is re-encoded, so the picture stays at its original quality.

To drop the sound completely, use our Mute Video tool, which removes the audio track.
