Question 1

Which audio formats are supported?

Accepted Answer

You can convert between MP3, WAV, and OGG. The input can also be other common formats like M4A or FLAC — only the output format is limited to these three.

Question 2

Will converting reduce audio quality?

Accepted Answer

Converting from a lossy format (like MP3) to another lossy format (like OGG) won't recover lost quality, but converting to WAV is lossless — it just uncompresses the audio, so there's no additional quality loss versus the source.

Question 3

Why does the first conversion take longer than expected?

Accepted Answer

The first time you use any audio/video tool on this site, your browser downloads a ~30MB video-processing engine (ffmpeg compiled to WebAssembly). It's cached afterward, so later conversions start instantly.

Question 4

Is there a file size limit?

Accepted Answer

Yes, 200MB, since all processing happens in your browser tab rather than on a server.

Question 5

Is my audio file uploaded to a server?

Accepted Answer

No. Conversion happens entirely in your browser using WebAssembly — your file never leaves your device.
