Question 1

What audio formats can I convert?

Accepted Answer

You can convert between WAV, OGG (Vorbis/Opus), WebM (Opus), AAC (MP4/M4A) and other formats supported by your browser. Output depends on browser support.

Question 2

Is my audio uploaded to a server?

Accepted Answer

No. All audio conversion happens entirely in your browser using the Web Audio API. Your files never leave your device.

Question 3

Can I adjust audio quality?

Accepted Answer

Yes. You can set the output sample rate (8000–48000 Hz) and bitrate for lossy formats. Higher settings produce better quality but larger files.

Question 4

Why are some formats not available?

Accepted Answer

Available output formats depend on your browser. Chrome supports WebM (Opus) and OGG (Vorbis), while Safari supports AAC (MP4). WAV is universally supported.
