Local audio utility

Compress audio. Keep it local.

Compression controls are not enabled yet. The current workbench converts supported local files to WAV and does not reduce file size. Your file never enters a server queue.

Output format

This route is mapped from the survey, but the browser export currently supports WAV only. MP3 and M4A encoders are not enabled yet.

Choose a file to unlock the conversion path.

Browser-native processing keeps the original on your device. Output quality depends on the decoder available in your browser.

Route intent from the supplied CSV: compress mp3 / compress audio mp3. The browser capability is explicit, so a limited decoder never looks like a completed upload.
