PixelTools

Volume changer for audio and video

Make an audio or video file louder or quieter — free, instant, and private. Nothing leaves your device.

Drop an audio or video file here, or click to browse

MP3, WAV, M4A, OGG, FLAC, MP4, MOV, WebM, MKV, or AVI — up to 2GB

Everything you need to fix a file's volume

Boost or lower from 0% to 300%

One slider with clear presets. Mute a track, halve it, double it, or fine-tune in 5% steps.

Works on video and audio

The same tool handles MP3, WAV, M4A, OGG, FLAC, MP4, MOV, WebM, MKV, and AVI, so there is no need to hunt for a separate video volume changer.

Keeps your picture and format

Video is copied without re-encoding when its format allows, so the picture is untouched. Audio files come back in the format you uploaded.

No upload, no waiting

Processing starts the moment you press the button. There is no upload queue and no server processing time.

Private by design

Your files never leave your device. PixelTools runs entirely in your browser using ffmpeg.wasm.

Three steps to a louder or quieter file

  1. 1

    Upload your audio or video file

    Drag and drop a file onto the page, or click to browse. Supports MP3, WAV, M4A, OGG, FLAC, MP4, MOV, WebM, MKV, and AVI files up to 2GB.

  2. 2

    Set the new volume

    Drag the slider from 0% (muted) up to 300%, or tap a preset: Mute, Half, Reset, or Double. 100% leaves the volume as it is.

  3. 3

    Download the result

    The new volume is applied in your browser and saved in a matching format. A video keeps its picture untouched whenever its format allows. Nothing is uploaded to any server.

Built for quiet recordings and uneven files

Whether you're lifting a quiet phone video, evening out a voice memo, or turning down a track that's too loud, PixelTools changes the volume in your browser in seconds.

Quiet phone videos

Lift the sound on a clip you shot from across the room, or from a concert, so people can hear it without cranking their speakers.

Voice memos and recordings

Make an interview, lecture, or voice memo loud enough to follow on a laptop or phone speaker.

Uneven music files

Bring a track that sits quieter than the rest of your playlist up to a comparable level, or turn down one that is too loud.

Presentations and editing prep

Match the level of a clip to the rest of your project before you drop it into a video editor or slide deck.

Frequently asked questions

How do I make a video louder?

+

Upload the video, drag the volume slider above 100% (150% is a good starting point for a quiet recording), and download the result. The picture is copied untouched when its format allows, and only the sound is changed.

Can I boost an MP3's volume with this?

+

Yes. Drop in an MP3 (or WAV, M4A, OGG, or FLAC), raise the slider, and download a louder file in the same format. You can go up to 300% of the original level.

Will boosting the volume cause distortion?

+

It can. Boosting multiplies the signal, and a recording that is already near its loudest point will clip (crackle) when pushed higher. If the result sounds harsh, try a lower setting. Quiet recordings, such as phone videos and voice memos, usually take a 150% to 200% boost cleanly.

Can I lower the volume or mute a file?

+

Yes. Drag the slider below 100% to make a file quieter, or press Mute to silence the track completely. To remove the audio track from a video altogether, use the Remove Audio from Video tool instead.

Are my files uploaded to a server?

+

No. PixelTools changes the volume entirely in your browser using ffmpeg.wasm. Your files never leave your device, and nothing is stored anywhere.

Does changing the volume reduce video quality?

+

No. The video stream is copied as it is, so the picture is identical to the original. Only the audio track is re-encoded. If a file's video format cannot be copied into an MP4 or WebM, PixelTools re-encodes it at high quality instead.

What formats do I get back?

+

Audio files come back in the format you uploaded. Video files come back as MP4, except WebM files, which stay WebM.

Is it free?

+

Yes, completely free with no limits, no watermark, and no account required.
