Free online audio tools for MP3 conversion, WAV conversion, extracting audio from video, audio merge, audio trim, audio compression, microphone recording, and audio-to-text transcription. Conversion, trimming, merging, compression, and recording export run locally in your browser, while transcription can load an open-source Whisper model in the browser.
Audio and video are processed locally in your browser first; FFmpeg WASM and transcription model files are downloaded only when needed.
