The video is processed by your device: allow a few seconds for a format change, longer for compression.
Many videos and recordings saved from the web are in WebM. Convert them to MP3 to keep only the audio and play it on any player, phone or car stereo. The Opus or Vorbis track is re-encoded to MP3.
How to convert WebM to MP3
- 1Drop your WebM files in the box, or click to pick them. You can add several at once.
- 2MP3 is already selected. Open the settings if you want to change the quality, the size or the background.
- 3Download each file, or everything at once as a .zip. Nothing was uploaded: the conversion happened on your device.
The formats
WebM
The web's open video format, in VP9 or AV1 with Opus audio. It is light and plays in Chrome, Firefox and Edge, but less well on iPhones, in editing software and on some social networks.
MP3
The universal audio format. It compresses with loss, almost inaudibly at 192 kbps, and plays on every device, player and app. It is the format to aim for when sharing audio.
Your files stay with you
The conversion runs in your browser, with your device's decoders. No file is uploaded, no copy is kept, and nobody but you sees your photos or videos. You can check it in the Network tab of your browser's developer tools: none of your files goes out.
Frequently asked questions
My WebM file only has audio, does it work?
Yes: an audio-only WebM converts the same way, straight to MP3.
Can I get the audio of an online video?
The tool converts files stored on your device. Only download videos whose audio you have the right to use.
Is the converter really free?
Yes, with no sign-up, no watermark and no limit on the number of files. The conversion runs on your device and costs us nothing, so there is nothing to charge you for.
Are my files sent anywhere?
No. They are read and converted in your browser, then saved straight to your device. No server receives them.
Is there a maximum size?
The limit is your device's memory. Photos and audio files go through without trouble; for a video of several gigabytes, a computer does better than a phone.
Does it work on a phone?
Yes, on iPhone and Android, in Safari, Chrome or Firefox. For video, an up-to-date browser is needed: it provides the decoders being used.
