Audio to MP3 — frequently asked questions
How do I convert WAV or FLAC to MP3 for free?
Drop your audio file into the tool above and click Convert. FFmpeg runs in your browser and outputs a standard MP3 that plays on every device and platform.
Is my audio uploaded to a server?
No. The conversion runs locally in your browser via WebAssembly — your recordings never leave your device unless you choose to share them.
Will converting to MP3 reduce quality?
MP3 is a lossy format, but at the bitrate this tool uses the difference from WAV or FLAC is inaudible for most listeners and use cases. Keep your originals if you need archival quality.
Why convert to MP3?
MP3 files are dramatically smaller than WAV/FLAC and play everywhere — email, messaging apps, car stereos, and every browser. It's the safest format to send to someone else.
