Video and Audio Converter

Convert videos and audio without installing anything and without uploading your files: everything is processed in your own browser. Extract a video's audio as MP3, shrink videos for messaging or email, turn iPhone MOV videos into MP4, make GIFs, trim clips and convert audio between MP3, M4A, WAV and OGG, several files at a time.

A video converter that never uploads your files

Most online converters upload your video to a server. Here conversion runs in your browser with WebCodecs, using your own device's hardware acceleration, so there are no queues, watermarks or daily limits.

MP4 to MP3, compression, GIFs and trimming

Extract audio from music videos, lectures and podcasts; compress phone videos to 1080p, 720p or 480p H.264; convert MOV and WEBM to MP4; create GIFs up to 30 seconds; and trim clips without re-encoding whenever possible.

Frequently asked questions

Is it free?

Yes. The site is supported by ads, so you never pay or need to create an account.

Are my videos uploaded?

No. Conversion uses your browser's built-in video features (WebCodecs) and happens entirely on your device. Your files never leave it.

How do I convert MP4 to MP3?

Tap MP4 to MP3, pick a quality (128, 192 or 320 kbps) and add the video. 192 kbps is the best balance; 320 kbps is the highest MP3 quality.

How do I make a video smaller?

Use Compress video at the Recommended level (720p). Phone videos usually become 3 to 10 times smaller. Choose Strong (480p) for even smaller files.

Which formats are supported?

Video: MP4, MOV, M4V, WEBM, MKV and MPEG-TS. Audio: MP3, M4A/AAC, WAV, OGG, Opus and FLAC. Output: MP3, M4A, WAV, OGG, MP4, WEBM and GIF. AVI and WMV are not supported yet.

Does it work on mobile?

Yes. The page adapts to your screen and does not require installing any app.
