Question 1

Is my audio sent to a server?

Accepted Answer

No, conversion is done entirely locally using ffmpeg.wasm.

Question 2

Which input formats are supported?

Accepted Answer

MP3, WAV, OGG, M4A, and other formats recognized by FFmpeg are supported.

Question 3

Does the sound quality degrade?

Accepted Answer

Converting between lossy formats (MP3, OGG) may introduce a small quality loss; WAV keeps audio uncompressed.

Question 4

Why is the first conversion slower?

Accepted Answer

On first use, the browser downloads and initializes the FFmpeg engine, which is then cached.

Question 5

Is there a limit on audio length?

Accepted Answer

There's no hard limit, but very long files take longer to process and use more browser memory.
