Will I lose audio quality converting WAV to MP3?

Some quality loss is inevitable because MP3 is lossy and WAV is lossless. However, at 192 kbps, the loss is inaudible on consumer headphones and speakers. Trained ears in professional listening environments may detect subtle differences, but for podcasts, voice, and shared music it's transparent.

Why is my WAV file so large?

WAV stores uncompressed PCM audio — every sample is saved exactly as recorded. A CD-quality (44.1 kHz, 16-bit, stereo) WAV is about 10MB per minute. This is great for editing, terrible for sharing.

Are my audio files uploaded to a server?

No. FFmpeg.wasm processes everything locally in your browser. Your recordings never leave your device.

What bitrate will the MP3 be?

192 kbps CBR (constant bit rate). This is the standard for podcast distribution and high-quality sharing. It's a good balance between file size and audio quality.

Can I convert WAV recordings from Audacity, GarageBand, or Logic?

Yes. WAV files exported from any DAW (Audacity, GarageBand, Logic Pro, Reaper, Pro Tools) are supported.

How much smaller will the MP3 be?

Typically 85–92% smaller. A 40MB WAV becomes approximately 3–5MB as a 192 kbps MP3.

Can I batch convert multiple WAV files?

Yes — up to 20 WAV files at once. They convert in parallel and you can download all as a ZIP.

What is the maximum WAV file size?

100MB per file. For WAV files larger than this (common in long recording sessions), use desktop FFmpeg for batch processing.
