Convert M4A, AAC and other audio files to MP3 at 64 to 320 kbps. The file is processed inside your browser and never uploaded to a server.
Shrink a heavy WAV into a compact AAC using the browser MediaRecorder. Support varies: if the codec is missing, the page says so instead of failing quietly.
Compress WAV into FLAC with no quality loss right in your browser: the file roughly halves while sample rate and bit depth stay exact. Nothing is uploaded.
Compress a WAV into an M4A file in the browser. Export relies on MediaRecorder, so availability depends on which browser you use.
Shrink a heavy PCM WAV into an MP3 without uploading it, turning a file too big to email into a normal attachment.
Convert sound between MP3, WAV, FLAC, AAC, M4A, OGG and WebM. Conversion runs in the browser and the track is never uploaded.
This subcategory holds paired audio converters. WAV acts as the intermediate format: compressed versions are built from it, and finished recordings are unpacked into it for editing. Every pair works both ways, so the reverse operation always sits nearby. The processing happens on your device.
