Frequently Asked Questions
What audio formats can I convert?+
You can convert between MP3, WAV, FLAC, OGG, M4A, OPUS, and AIFF. As input, most common audio files work too, including AAC, WMA, and audio tracks inside WebM containers.
Is my audio uploaded anywhere?+
No. All conversion happens locally in your browser using FFmpeg WebAssembly. Your audio files never leave your device, so it is safe for voice notes, recordings, and anything sensitive.
What is the difference between MP3 and FLAC?+
MP3 is a lossy format — it discards some detail to keep files small. FLAC is lossless — it preserves every detail but produces larger files. WAV and AIFF are uncompressed, which gives the largest files of all.
Which bitrate should I choose?+
For music, use High (256 kbps) or Best (320 kbps) for the best balance of size and quality. For podcasts and voice recordings, Low or Medium is usually indistinguishable from the source.
Can I convert without losing quality?+
Yes. Choose WAV, FLAC, or AIFF — all three are lossless formats that preserve the original audio quality exactly.
