Audio & video tools

14 free media tools: convert, trim, join, split, normalize and change the speed of audio, visualize waveforms, edit metadata, compress and trim video, extract audio, convert subtitles, transcribe speech and trim silence.

Note: Everything runs in your browser — your media is never uploaded. Audio tools output standard 16-bit PCM WAV files. Video tools re-encode with the browser's MediaRecorder (WebM). Speech-to-Text uses the browser's built-in recognition and only works in Chrome, Edge and Safari.
