Convert audio format
Convert MP3, WAV, M4A, AAC, OGG, FLAC and WebM audio to M4A, OGG, WebM or WAV, with bitrate, sample rate and channels. Encoding uses the browser; MP3 output is not available yet.
Extract audio from video
Take the sound track out of MP4, MOV, MKV or WebM video, either unchanged in its own container or converted to M4A, OGG, WebM or WAV, optionally trimmed.
Trim audio
Cut a time range out of MP3, WAV, M4A, AAC, OGG, FLAC or WebM audio without re-encoding, so quality is unchanged.
Change audio volume
Make audio louder or quieter by a percentage, clipping at full scale, and save it as M4A, OGG, WebM or WAV.
Screen recorder
Record a screen, window or tab with its sound and your microphone if you like, and save MP4 or WebM.
Convert video format
Convert between MP4, WebM, MKV and MOV; MP4 and MOV get H.264 video and AAC sound so any player opens them, and other formats copy streams when they can. Scale down, remove the sound or trim at the same time. Encoding uses the browser.
